Microsoft and Qualcomm Collaborate To Bring Windows 10, x86 Emulation To Snapdragon Processors (anandtech.com)
An anonymous reader quotes a report from AnandTech: Today at Microsoft's WinHEC event in Shenzhen, China, the company announced that it's working with Qualcomm to bring the full Windows 10 experience to future devices powered by Snapdragon processors. These new Snapdragon-powered devices should support all things Microsoft, including Microsoft Office, Windows Hello, Windows Pen, and the Edge browser, alongside third-party Universal Windows Platform (UWP) apps and, most interestingly, x86 (32-bit) Win32 apps. They should even be able to play Crysis 2. This announcement fits nicely with Microsoft's "Windows Everywhere" doctrine and should come as no surprise. It's not even the first time we've seen Windows running on ARM processors. Microsoft's failed Windows RT operating system was a modified version of Windows 8 that targeted the ARMv7-A 32-bit architecture. It grew from Microsoft's MinWin effort to make Windows more modular by reorganizing the operating system and cleaning up API dependencies. The major change with today's announcement over Windows RT and UWP is that x86 apps will be able to run on Qualcomm's ARM-based SoCs, along with support for all of the peripherals that are already supported with Windows 10. This alone is a huge change from Windows RT, which would only work with a small subset of peripherals. Microsoft is also focusing on having these devices always connected through cellular, which is something that is not available for many PCs at the moment. Support will be available for eSIM to avoid having to find room in a cramped design to accommodate a physical SIM, and Microsoft is going so far as to call these "cellular PCs" meaning they are expecting broad support for this class of computer, rather than the handful available now with cellular connectivity. The ability to run x86 Win32 apps on ARM will come through emulation, and to demonstrate the performance Microsoft has released a video of an ARM PC running Photoshop. -
Intel Announces Atom E3900 Series - Goldmont for the Internet of Things (anandtech.com)
Intel has announced the Atom E3900 series. Based upon the company's latest generation Goldmont Atom CPU core, the E3900 series will be Intel's most serious and dedicated project yet for the IoT market. AnandTech adds: So what does an IoT-centric Atom look like? By and large, it's Broxton and more. At its core we're looking at 2 or 4 Goldmont CPU cores, paired with 12 or 18 EU configurations of Intel's Gen9 iGPU. However this is where the similarities stop. Once we get past the CPU and GPU, Intel has added new features specifically for IoT in some areas, and in other areas they've gone and reworked the design entirely to meet specific physical and technical needs of the IoT market. The big changes here are focused on security, determinism, and networking. Security is self-evident: Intel's customers need to be able to build devices that will go out into the field and be hardened against attackers. Bits and pieces of this are inerieted from Intel's existing Trusted Execution Technology, while other pieces, such as boot time measuring, are new. The latter is particularly interesting, as Intel is measuring the boot time of a system as a canary for if it's been compromised. If the boot time suddenly and unexpectedly changes, then there's a good chance the firmware and/or OS has been replaced. -
Samsung Announces 10nm SoC In Mass-Production (anandtech.com)
An anonymous reader quotes a report from AnandTech: Today Samsung announced mass production of a SoC built on its third-generation 10nm "10LPE" manufacturing node. It was only this January that Samsung announced mass production of its 14LPP process that ended up being used in the Exynos 8890 and the Snapdragon 820 powering up a large amount of flagship devices this year. There wasn't any specification as to what kind of SoC the mass production announcement is referring to, but it's very likely we're talking about S.LSI's next generation Exynos -- or maybe even Qualcomm's Snapdragon 820 successor, both of which we'll hopefully hear official announcements from in the coming months. The process promises some significant speed and power efficiency advantages over current generation designs so it's likely the next generation of devices will see a large boost, similarly to how the first 14/16 SoCs had large improvements over previous generation 20/28nm designs. Interestingly the new SoCs will have an edge on recent and upcoming designs still being released on 16nm manufacturing processes, such as Apple's A10 or other TSMC customers who have to wait till next year for 10FF. Samsung writes in its press release: "Samsung's new 10nm FinFET process (10LPE) adopts an advanced 3D transistor structure with additional enhancements in both process technology and design enablement compared to its 14nm predecessor, allowing up to 30-percent increase in area efficiency with 27-percent higher performance or 40-percent lower power consumption. In order to overcome scaling limitations, cutting edge techniques such as triple-patterning to allow bi-directional routing are also used to retain design and routing flexibility from prior nodes." -
USB-IF Publishes Audio Over USB Type-C Specifications (anandtech.com)
An anonymous reader quotes a report from AnandTech: The USB Implementers Forum this week published the USB Audio Device Class 3.0 (direct download) specification, which standardizes audio over USB Type-C interface. The new spec enables hardware makers to eliminate traditional 3.5mm mini-jacks from their devices and use USB-C ports to connect headsets and other audio equipment. Makers of peripherals can also build their audio solutions, which use USB-C instead of traditional analog connectors. Developers of the standard hope that elimination of mini-jacks will help to make devices slimmer, smarter and less power hungry. As reported, the USB Audio Device Class 3.0 specification supports both analog and digital audio. Analog audio is easy to implement and it does not impact data transfers and other functionality of USB-C cables since it uses the two secondary bus (SBU) pins. The USB ADC 3.0 defines minimum interoperability across analog and digital devices in order to avoid confusion of end-users because of incompatibility. In fact, all ADC 3.0-compliant hosts should support the so-called headset adapter devices, which allow to connect analog headsets to USB-C. However, digital audio is one of the primary reasons why companies like Intel wanted to develop the USB-C audio tech on the first place, hence, expect them to promote it. According to the USB ADC 3.0 standard, digital USB-C headphones will feature special multi-function processing units (MPUs), which will, to a large degree, define the feature set and quality of headsets. The MPUs will handle host and sink synchronization (this is a key challenge for digital USB audio), digital-to-analog conversion, low-latency active noise cancellation, acoustic echo canceling, equalization, microphone automatic gain control, volume control and others. Such chips will also contain programmable amplifiers and pre-amplifiers, which are currently located inside devices. Besides, USB ADC 3.0-compatible MPUs will also support USB Audio Type-III and Type-IV formats (the latest compressed formats), but will retain compatibility with formats supported by ADC 1.0 and 2.0. Finally, among the mandated things set to be supported by USB-C Audio devices are new Power Domains (allows devices to put certain domains in sleep mode when not in use) as well as BADD (basic audio device definition) 3.0 features for saving power and simplified discovery and management of various audio equipment (each type of devices has its own BADD profile). -
Qualcomm's New Snapdragon 821 Is 10 Percent Faster Than the 820 (theverge.com)
An anonymous reader shares a report on The Verge: Qualcomm has announced a new flagship mobile processor called the Snapdragon 821. The 821 is a slight update to the Snapdragon 820 that debuted in smartphones earlier this year and promises modest performance gains. The 820 has been found in virtually every high-end Android smartphone this year, including Samsung's Galaxy S7 and S7 Edge, the HTC 10, the LG G5, the OnePlus 3, and the Xiaomi Mi5. In our experience, we've found it to be quite a capable chip, with great performance and efficient power utilization. It's a far cry from last year's Snapdragon 810, which was plagued with performance and thermal issues. Qualcomm says the Snapdragon 821 builds upon the 820's features, but provides a 10 percent performance increase. Its quad-core CPU runs at 2.4GHz.AnandTech has more details. -
AMD RX 480 Offers Best-in-Class Performance For $199/$239
Reader Vigile writes: It's been a terribly long news cycle, but today is finally the day reviews and sales start of the new AMD Radeon RX 480 graphics card based on the company's latest Polaris architecture and built on 14nm FinFET process technology. With a starting price tag of $199 for the 4GB model and $239 for the 8GB, the RX 480 has some interesting performance characteristics. Compared to the GeForce GTX 970, currently selling for around $280, the RX 480 performs +/- 5-10% in DX11 games but PC Perspective found that the RX 480 was as much as 40% faster in DX12 titles like Gears of War, Hitman and Rise of the Tomb Raider. Compared to previous AMD products, the RX 480 is as fast as a Radeon R9 390 but uses just 150 watts compared to 275 watts for the previous generation. Chances are that NVIDIA will have a competing product based on Pascal available sometime in July, so AMD's advantage may be short-lived; but in the meantime, the Radeon RX 480 is clearly the best GPU for $200.AnandTech has more details. -
Razer Announces Open Source VR HDK2 Headset, And $5 Million Developer Fund (anandtech.com)
Razer has announced its second Open Source Virtual Reality (OSVR) headset. Dubbed HDK2, the new headset from the gaming-hardware company is priced at $400. As for the specifications, the HDK2 offers dual OLED display of screen resolution 2,160x1,200 pixels while retaining the 90hz low-latency refresh rate. The original HDK will continue to be available for purchase at $300. On the sidelines, the company announced a $5 million to studios working in this space. AnandTech reports: OSVR has an open framework so it will be able to work with a variety of controllers, and as more control mechanisms become available, it should be able to support them. The HDK system supports several content technologies, including SteamVR, and they plan to announce more content soon. On that note, OSVR is also announcing a $5 million developer fund. Their goal is to ensure unrestricted access of VR content on all hardware. If you are a VR content developer, you can apply to this fund. If approved by the fund, and OSVR support is added to the content, Razer, or other future contributors, will purchase game codes in bulk to help compensate developers for their integration time, and the fund will also assist with marketing and promotional support.Also at E3, Sony announced that its $399 PlayStation VR wil be available to purchase in the U.S. from October 13. -

Details of Microsoft's rumored new console have dropped ahead of the company's conference at E3 tradeshow Monday. It appears the long-anticipated smaller and more powerful variant of company's current console is real. According to a leaked press render, Microsoft will be announcing the Xbox One S (where S stands for Slim) at the gaming event. The Xbox One S will be 40 percent smaller than the Xbox One, and pack in more powerful processing and graphics muscle. According to the render, the Xbox One S will come with a 2TB hard drive, and feature support for 4K video playback and High Dynamic Range. According to separate reports, the Xbox One S is likely to be priced at $399 for the 2TB variant. Update: 06/13 16:58 GMT by M : Microsoft has officially taken the wraps off the product. It will be available for purchase starting August. AnandTech has more details.Also at its event, Microsoft announced Xbox Play Anywhere. The Verge reports: It lets you buy participating cross-platform games once, and own them on both platforms. If you buy a game on Xbox One it will simply appear in your Windows 10 library, and vice versa, and your saved games, achievements, and other information will carry over between the two versions.Microsoft also unveiled "Project Scorpio", a high-powered Xbox One launching next year that is capable of supporting 4K content as well as virtual reality headsets. "We are creating more choice in your gaming experience than ever before," said Xbox chief Phil Spencer to open Microsoft's E3 conference. No word on its pricing yet. -
NVIDIA Unveils GeForce GTX 1080, GTX 1070, Faster Than Titan X For a Lot Less (hothardware.com)
MojoKid writes (edited and condensed): NVIDIA has unveiled its next-generation Pascal-based GeForce graphics cards -- known as the GeForce GTX 1080 and GeForce GTX 1070. NVIDIA's Pascal architecture is based on 16nm FinFET technology, similar to that of NVIDIA's high-end data center Tesla P100 processing engine though the GeForce cards are targeted at the consumer gaming market. NVIDIA's GP104 GPU at the heart of the new GeForce cards is comprised of some 8 billion transistors and features a 256-bit memory interface with 8GB of Micron GDDR5X graphics memory on the GeForce GTX 1080. The GTX 1070, however, employs standard GDDR5. The core clock speed of the GeForce GTX 1080 hit 2.1GHz at one point during the demonstration, though GTX 1070 clocks were not disclosed. NVIDIA CEO Jen-Hsun Huang claimed the new GeForce GTX 1080 is faster than a pair of GeForce GTX 980 cards in SLI and faster than the company's very expensive Titan X graphics card but at half the price. The new GeForce GTX 1080 will be offered in two versions, a standard card with an MSRP of $599 or a highly-overclockable Founders Edition for $699. The standard GTX 1070 will arrive at $379, while a Founders Edition will be priced at $449. Availability for the GTX 1080 is slated for May 27th and the GTX 1070 for June 10. Anand Tech has more information. -
HP Says It Made the World's Thinnest Laptop (time.com)
An anonymous reader writes: HP claims that its Spectre laptop, unveiled April 5, is the world's thinnest laptop. It measures 10.4mm thick or 0.41 inches. That would mean that it's slimmer than the 12-inch MacBook (0.52), MacBook Air (0.68 inches) and Dell XPS 13 (0.59 inches) at their thickest points. It's also thinner than the 0.52-inch Razer Blade Stealth. The new notebook is equipped with an advertised nine-hour battery life, 13-inch HD 1920 x 1080 resolution display, and sixth generation Intel Core i5 or i7 processor. The Spectre will be available for pre-order on April 25 for $1,169.99 before it hits Best Buy stores on May 22 for $1,249.99. -
Apple's New Safari Technology Preview Browser Is Aimed At Web Developers
Sarah Perez reports for TechCrunch: Apple today announced it's expanding its efforts in the area of web development, with the launch of a new version of its Safari web browser, designed specifically for developers. Called Safari Technology Preview, the company says this browser will allow developers to get an early look at upcoming web technologies in OS X and iOS, including things like the latest layout technologies, visual effects, and other developer tools. The idea is to allow developers to more easily get their hands on these technologies and be able to experiment, then offer feedback to Apple earlier on so the company can make the necessary improvements. AnandTech's Brandon Chester elaborates: It's available from Apple's developer website, and updates will come every two weeks via the Mac App Store. This makes the list of changes and additions easily accessible with each update, and because the builds are signed by Apple there's full support for iCloud integration. [...] One important thing to note about the Safari Technology Preview is that, while the app is available from Apple's developer site, you don't need to be a registered developer paying the yearly iOS and OS X publishing fee to access it. Since the target audience consists mainly of programmers building websites and web applications, it doesn't make sense to limit it to developers building native apps for iOS and OS X. -
Intel Says It Will Move Away From 'Tick-Tock' Development Cycle
An anonymous reader writes: In its latest annual report, Intel says that it will be moving away from its decade-old "tick-tock" strategy (PDF) for developing new chips. From the company's 10-K filing, "We expect to lengthen the amount of time we will utilize our 14nm and our next generation 10nm process technologies, further optimizing our products and process technologies while meeting the yearly market cadence for product introductions." Anand Tech's Ian Cutress explains, "Intel's Tick-Tock strategy has been the bedrock of their microprocessor dominance of the last decade. Throughout the tenure, every other year Intel would upgrade their fabrication plants to be able to produce processors with a smaller feature set, improving die area, power consumption, and slight optimizations of the microarchitecture, and in the years between the upgrades would launch a new set of processors based on a wholly new (sometimes paradigm shifting) microarchitecture for large performance upgrades. However, due to the difficulty of implementing a 'tick', the ever decreasing process node size and complexity therein, as reported previously with 14nm and the introduction of Kaby Lake, Intel's latest filing would suggest that 10nm will follow a similar pattern as 14nm by introducing a third stage to the cadence." -

AMD's XConnect Brings Native Driver Support For Thunderbolt 3 Graphics Cards
AnandTech writes about AMD's XConnect technology: Last night AMD issued a driver update that brought support for a new technology, XConnect. In a nutshell, XConnect is AMD's trade name for running external video cards via Thunderbolt 3, a long-awaited development that Thunderbolt owner Intel is finally getting behind and allowing. [...] AMD is also laying out the technical requirements for supporting XConnect. Not just any laptop/desktop with Thunderbolt 3 can support an external GPU, as there are specific hardware and software requirements, which is why the Blade Stealth is the first qualified laptop. In particular, laptops need to support what is being called the Thunderbolt 3 external graphics standard, or eGFX for short. -
HAMR Hard Disk Drives Postponed To 2018 (anandtech.com)
An anonymous reader writes: Unfortunately the hard disk drive industry is not ready to go live with Heat-assisted Magnetic Recording (HAMR). The technology is yet not reliable enough for mass production. Over the years, producers of hard drives, platters and recording heads have revealed various possible timeframes for commercial availability of drives with HAMR technology. Their predictions were not accurate. The current goalpost is set to year 2018. While solid state disks based on Flash memory keep seeing rapid improvements as well, HDDs still kick butt in scenarios where high areal density is more important than ripping transfer speeds. The areal density of HAMR products is predicted to exceed 1.5 Tb per square inch. -
AMD's 'Crimson' Driver Software Released (anandtech.com)
An anonymous reader writes: Yesterday marked the launch of AMD's 'Crimson' driver software. It replaces the old Catalyst driver software, and represents a change in how AMD develops bug fixes, improves performance, and adds features. AnandTech took a detailed look at the new driver software. They say, "By focusing feature releases around the end of the year driver, AMD is able to cut down on what parts of the driver they change (and thereby can possibly break) at other times of the year, and try to knock out all of their feature-related bugs at once. At the same time it makes the annual driver release a significant event, as AMD releases a number of new features all at once. However on the other hand this means that AMD has few features launching any other time of the year, which can make it look like they're not heavily invested in feature development at those points." On a more positive note, the article adds, "Looking under the hood there's no single feature that's going to blow every Radeon user away at once, but overall there are a number of neat features here that should be welcomed by various user groups. ... Meanwhile AMD's radical overhaul of their control panel via the new Radeon Settings application will be quickly noticed by everyone." -
Microsoft Surface Pro 4 and Surface Book Reviews
An anonymous reader writes: Anandtech posted reviews of the Microsoft Surface Pro 4 and the Microsoft Surface Book today. They write: "After launching Surface Pro 3 with Haswell in 2014, Microsoft — like so many manufacturers — opted to skip the short-lived Broadwell generation of Intel CPUs in favor of making the larger jump to Skylake. Skylake brings with it notable increases in both CPU and GPU performance, particularly in the mobile space thanks to a series of optimizations and the use of Intel's leading 14nm manufacturing node," about the Pro 4 and with regards to the Book, "The basis of the Surface Book is that it is designed to be used as a laptop most of the time, but the display can be removed as a Clipboard for use with the pen. The Surface Book is certainly not the first device to do this, but it does some things in new ways that are pretty interesting." -

Intel Launches Onslaught of Skylake CPUs For Laptops, Hybrids and Compute Stick
MojoKid writes: Intel is following up on its Skylake launch bonanza by opening the floodgates on at least two dozen SKUs mostly covering the mobile sector. The company is divvying up the range into four distinct series. There's the Y-Series, which is dedicated to 2-in-1 convertibles, tablets, and Intel's new Compute Stick venture. Then there's the U-Series, which is aimed at thin and light notebooks and "portable" all-in-one machines. The H-Series is built for gaming notebooks and mobile workstations, while the S-Series is designated for desktops, all-in-one machines, and mini PCs. Also, the Y-Series that was previously known as simply the Core M, (the chip found in products like the 12-inch Apple MacBook and Asus Transformer Book Chi T300) is now expanding into a whole family of processors. There will be Core m3, Core m5, and Core m7 processors, similar to Intel's Core i3, Core i5, and Core i7 CPU models in other desktop and notebook chips. -
Ask Slashdot: Best Big Battery Phone?
An anonymous reader writes: Samsung's announcement today of the Galaxy Note 5 and Galaxy S6+ was a disappointment to a lot of power users. The phones both use a 3,000 mAh, non-removable battery. This is presumably part of Samsung's quest for thinner and thinner phones, but it's bad news for those who prize function over form — particularly from a phone line that is ostensibly made for power users. So, those of you who have the pulse of the mobile industry: what's my best bet for a high end phone that doesn't compromise on battery life? Are there any devices on the horizon that are likely to have big batteries? I'm also wondering if I should just get a cheap phone to tide me over to the next generation of flagships. My current device is old and doesn't have the fast/quick-charge tech that modern ones do — does that work as advertised? -
OpenGL ES 3.2 & New Extensions Unveiled
An anonymous reader writes: With kicking off ACM SIGGRAPH '15, The Khronos Group came out with several big announcements, including the release of OpenGL ES 3.2 (which incorporates Android AEP functionality), confirmation that Google will support Vulkan on Android (when released), new desktop OpenGL extensions, and updates to the existing OpenCL 2.0 specification. They stopped short of releasing the heavily anticipated Vulkan Graphics API and also refrained from releasing a new desktop OpenGL version. They hope to have the Vulkan specification and its implementations released before year's end. -
Intel's Skylake Architecture Reviewed
Vigile writes: The Intel Skylake architecture has been on our radar for quite a long time as Intel's next big step in CPU design. We know at least a handful of details: DDR4 memory support, 14nm process technology, modest IPC gains and impressive GPU improvements. But the details have remained a mystery on how the "tock" of Skylake on the 14nm process technology will differ from Broadwell and Haswell. That changes today with the official release of the "K" SKUs of Skylake — the unlocked, enthusiast class parts for DIY PC builders. PC Perspective has a full review of the Core i7-6700K with benchmarks as well as discrete GPU and gaming testing that shows Skylake is an impressive part. IPC gains on Skylake over Haswell are modest but noticeable, and IGP performance is as much as 50% higher than Devil's Canyon. Based on that discrete GPU testing, all those users still on Nehalem and Sandy Bridge might finally have a reason to upgrade to Skylake. Other reviews available at Anandtech, Hot Hardware, [H]ard|OCP, and TechSpot. -
Microsoft Edge Performance Evaluated
An anonymous reader writes: Now that Windows 10 is close to launch, Anandtech has put Microsoft's new browser, Edge, through a series of tests to see how it stacks up against other browsers. Edge has shown significant improvements since January. It handily beats Chrome and Firefox in Google's Octane 2.0 benchmark, and it managed the best score on the Sunspider benchmark as well. But Chrome and Firefox both still beat Edge in other tests, by small margins in the Kraken 1.1 and HTML5Test benchmarks, and larger ones in WebXPRT and Oort Online. The article says, "It is great to see Microsoft focusing on browser performance again, and especially not sitting idle since January, since the competition in this space has not been idle either." -
Intel's Tick-Tock Cycle Skips a Beat
New submitter Ramze writes: Several outlets are reporting on Intel's confirmation that it will make three generations of 14nm processors, delaying the switch to 10nm. The planned 14nm Kaby Lake processor marks the first time Intel has skipped the "tick" of a die shrink on its regular "tick/tock" cycle. Production of Cannonlake processors on 10nm has been pushed back to the second half of 2017 — likely due to manufacturing difficulties. Intel reported earlier this year that it may have to switch away from silicon to exotic materials such as indium gallium arsenide to make the next shrink to 7nm. -
Intel Releases Broadwell Desktop CPUs: Core i7-5775C and i5-5675C
edxwelch writes: Intel has finally released their Broadwell desktop processors. Featuring Iris Pro Graphics 6200, they take the integrated graphics crown from AMD (albeit costing three times as much). However, they are not as fast as current Haswell flagship processors and they will be soon superseded by Skylake, to be released later this year. Tom's Hardware and Anandtech have the first reviews of the Core i7-5775C and i5-5675C. -
Intel 'Compute Stick' PC-Over-HDMI Dongle Launched, Tested
MojoKid writes: Intel has officially announced the availability of their Compute Stick HDMI dongle, and has lifted the embargo on early tests with the device. The Compute Stick is essentially a fully-functional, low-power, Atom-based system with memory, storage, and an OS, crammed into a dongle about 10cm long. There will initially be two compute sticks made available: one running Windows (model STCK1A32WFC) and another running Ubuntu (model STCK1A8LFC). The Windows 8.1 version of the Compute Stick is packing an Intel Atom Z3735F processor, with a single-channel of 2GB of DDR3L-1333 RAM and 32GB of internal storage, though out of the box only 19.2GB is usable. The Ubuntu version of the Compute Stick has as a similar CPU, but is packing only 1GB of RAM and 8GB of internal storage. All sticks have USB and MicroSD expansion capability. It doesn't burn through any benchmarks, but for multi-media playback, basic computing tasks, web browsing, HD video, or remote access, the Compute Stick has enough muscle to get the job done, and it's cheap, too: $99 — $149. -
New Samsung SSD 840 EVO Read Performance Fix Coming Later This Month
An anonymous reader writes: The Samsung SSD 840 EVO read performance bug has been on the table for over six months now. Initially Samsung acknowledged the issue fairly quickly and provided a fix only a month after the news hit the mainstream tech media, but reports of read performance degradation surfaced again a few weeks after the fix had been released, making it clear that the first fix didn't solve the issue for all users. Two months ago Samsung announced that a new fix is in the works and last week Samsung sent out the new firmware along with Magician 4.6 for testing, which will be available to the public later this month. -
Intel's Core M Performance Is Erratic Between Devices
An anonymous reader writes: AnandTech noticed some odd performance disparities with Intel's Core M CPU, a chip designed to bring high-powered processing to thin, fan-less devices. After investigating, they found that how OEMs build their laptops and tablets has a far greater effect on Core M performance than it does for other chips. "When an OEM designs a device for Core M, or any SoC for that matter, they have to consider construction and industrial design as well as overriding performance. ... This, broadly speaking, gives the OEM control over several components that are out of the hands of the processor designers. Screen size, thickness, industrial design, and skin temperature all have their limits, and adjusting those knobs opens the door to slower or faster Core M units, depending on what the company decides to target.
In the Core M units that we have tested at AnandTech so far this year, we have seen a variety of implementations with and without fans and in a variety of form factors. But the critical point of all of this comes down to how the OEM defines the SoC/skin temperature limitations of the device, and this ends up being why the low-end Core M-5Y10 can beat the high-end Core M-5Y71, and is a poignant part of our tests. Simply put, if the system with 5Y10 has a higher SoC/skin temperature, it can stay in its turbo mode for longer and can end up outperforming a 5Y71, leading to some of the unusual results we've seen so far." -
NVIDIA's GeForce GTX TITAN X Becomes First 12GB Consumer Graphics Card
Deathspawner writes: When NVIDIA announced its GeForce GTX TITAN X at GTC, no one was surprised that it'd be faster than the company's previous top-end card, the GTX 980. But what did impress many is that the company said the card would sport a staggering 12GB of VRAM. As Techgage found, pushing that 12GB is an exercise in patience — you really have to go out of your way to come even close. Additional reviews available at PC Perspective and AnandTech. The latter notes, "...from a technical perspective, the GTX Titan X and GM200 GPU represent an interesting shift in high-end GPU design goals for NVIDIA, one whose ramifications I’m not sure we fully understand yet. By building what’s essentially a bigger version of GM204, heavy on graphics and light on FP64 compute, NVIDIA has been able to drive up performance without a GM204-like increase in die size. At 601mm2 GM200 is still NVIDIA’s largest GPU to date, but by producing their purist graphics GPU in quite some time, it has allowed NVIDIA to pack more graphics horsepower than ever before into a 28nm GPU. What remains to be seen then is whether this graphics/FP32-centric design is a one-off occurrence for 28nm, or if this is the start of a permanent shift in NVIDIA GPU design." -
New Seagate Shingled Hard Drive Teardown
New submitter Peter Desnoyers writes: Shingled Magnetic Recording (SMR) drives are starting to hit the market, promising larger drives without heroic (and expensive) measures such as helium fill, but at a cost — data can no longer be over-written in place, requiring SSD-like algorithms to handle random writes.
At the USENIX File and Storage Technologies conference in February, researchers from Northeastern University (disclaimer — I'm one of them) dissected shingled drive performance both figuratively and literally, using both micro-benchmarks and a window cut in the drive to uncover the secrets of Seagate's first line of publicly-available SMR drives.
TL;DR: It's a pretty good desktop drive — with write cache enabled (the default for non-server setups) and an intermittent workload it performs quite well, handling bursts of random writes (up to a few tens of GB total) far faster than a conventional drive — but only if it has long powered-on idle periods for garbage collection. Reads and large writes run at about the same speed as on a conventional drive, and at $280 it costs less than a pair of decent 4TB drives. For heavily-loaded server applications, though, you might want to wait for the next generation. Here are a couple videos (in 16x slow motion) showing the drive in action — sequential read after deliberately fragmenting the drive, and a few thousand random writes. -
AMD Unveils Carrizo APU With Excavator Core Architecture
MojoKid writes: AMD just unveiled new details about their upcoming Carrizo APU architecture. The company is claiming the processor, which is still built on Global Foundries' 28nm 28SHP node like its predecessor, will nonetheless deliver big advances in both performance and efficiency. When it was first announced, AMD detailed support for next generation Radeon Graphics (DX12, Mantle, and Dual Graphics support), H.265 decoding, full HSA 1.0 support, and ARM Trustzone compatibility. But perhaps one of the biggest advantages of Carrizo is the fact that the APU and Southbridge are now incorporated into the same die; not just two separates dies built into and MCM package.
This not only improves performance, but also allows the Southbridge to take advantage of the 28SHP process rather than older, more power-hungry 45nm or 65nm process nodes. In addition, the Excavator cores used in Carrizo have switched from a High Performance Library (HPL) to a High Density Library (HDL) design. This allows for a reduction in the die area taken up by the processing cores (23 percent, according to AMD). This allows Carrizo to pack in 29 percent more transistors (3.1 billion versus 2.3 billion in Kaveri) in a die size that is only marginally larger (250mm2 for Carrizo versus 245mm2 for Kaveri). When all is said and done, AMD is claiming a 5 percent IPC boost for Carrizo and a 40 percent overall reduction in power usage. -
Windows 10 IE With Spartan Engine Performance Vs. Chrome and Firefox
MojoKid writes: In Microsoft's latest Windows 10 preview build released last week, Cortana made an entrance, but the much-anticipated Spartan browser did not. However, little did we realize that some of Spartan made the cut, in the form of an experimental rendering engine hidden under IE's hood. Microsoft has separated its Trident rendering engine into two separate versions: one is for Spartan, called EdgeHTML, while the other remains under its legacy naming with Internet Explorer. The reason Microsoft doesn't simply forego the older version is due to compatibility concerns. If you're running the Windows 10 9926 build, chances are good that you're automatically taking advantage of the new EdgeHTML engine in IE. To check, you can type 'about:flags' into the address bar. "Automatic" means that the non-Spartan Trident engine will be called-upon only if needed. In all other cases, you'll be taking advantage of the future Spartan web rendering engine. Performance-wise, the results with IE are like night and day in certain spots. Some of the improvements are significant. IE's Sunspider result already outperforms the competition, but it has been further improved. And with Kraken, the latency with the Spartan-powered Trident engine dropped 40%. Similar results are seen with a boost in the Octane web browser test as well. -
AnandTech's Intro To Semiconductor Tech
An anonymous reader writes: Computer hardware site AnandTech has posted a detailed introduction to semiconductor technology. It's deep enough to be insightful for understanding the chips that run your devices and the industry that built them, but also short enough that your eyes won't start bleeding in the process. The article starts by explaining why silicon is so important, and how a board is set up, structurally. Then it walks through transistor design and construction, and the underpinnings of CMOS logic. Finally, the article describes the manufacturing steps, including wafer creation, photolithography, and how metal is added/shaped at the end. They then go into the physics behind improving these components. It's a geeky and informative read. -
Early iPhone 6 Benchmark Results Show Only Modest Gains For A8
MojoKid writes: Historically speaking, we typically see impressive performance gains each time Apple releases a new custom processor for its mobile products. Certainly that was true of the A7 SoC, the world's first 64-bit smartphone processor. So, can we expect the same kind of performance bump from the iPhone 6 and iPhone 6 Plus, both of which sport the new custom A8 SoC? Maybe not. The iPhone 6 recently surfaced in results for the Basemark X benchmark and armed with a dual-core 1.4GHz Cyclone CPU and A8 GPU, the iPhone 6 scored 21,204.26 and a earned a place at the top of the chart, though not by much. By comparison, the iPhone 5s scored 20,253.80 in the same benchmark. In other words, the iPhone 6 is currently less than 5 percent faster than the iPhone 5s, at least as far as the Basemark X benchmark is concerned. -
Dell Demos 5K Display
An anonymous reader writes: Even though 4k displays are just making their way into consumer affordability, manufacturers are already pushing beyond. Dell has previewed a computer monitor it calls a "5k" display. The resolution is 5120x2880, stuffing 14,745,600 pixels on a 27" screen. For comparison, that's more than seven times the amount of pixels in a 1920x1080 display. Pixel density is 218 PPI, roughly the same as a 15" Retina MacBook Pro. ExtremeTech suggests, "As far as we're aware, no one is actually making 5120×2880 panels, especially not at 27 inches diagonal – so what we're probably looking at is two 2560x2880 panels squished together as a 'tiled display.'" Unfortunately, it's pricy, expected to cost around $2,500. But hopefully it will help drive 4k display prices even further toward mainstream availability. -
Moto 360 Reviews Arrive
An anonymous reader writes: Reviews for the Moto 360 smartwatch have started to roll in. David Pierce at The Verge praises the design: the circular display is framed by an unadorned, stainless steel shell, and fastened to your wrist with a simple leather strap. At the same time, he criticized the battery life, saying the device averaged around 12 hours of use before it needed to be charged. Pierce adds, "The Moto 360's most impressive feature is that I stopped noticing it almost immediately. Whenever I wear the LG G Watch or the Samsung Gear Live, I'm constantly compelled to fidget with it; there's this unexplainable feeling of having something alien on my wrist that is there because I need to use it. The 360, on the other hand, just vanished into the spot left on my wrist by the Seiko watch that conveniently died this week." AnandTech takes a deeper dive into the device's hardware, noting that the TI OMAP 3 processor is built on a somewhat old 45nm process, which necessitates higher power consumption than newer, smaller processes. The Wall Street Journal says it's easy to get used to speaking into your watch for basic functions, but the software — and thus, the Moto 360 as a whole — still isn't quite ready for prime time. However, almost all the reviews agree that the smartwatch's time is coming. -
Anand Lal Shimpi Retires From AnandTech
An anonymous reader writes: If you've built a PC in the past 17.5 years, chances are you read some hardware reviews on AnandTech at some point. The site's creator, Anand Lal Shimpi, has announced that he is retiring from the tech writing business. He said, "AnandTech started as a site that primarily reviewed motherboards, then we added CPUs, video cards, cases, notebooks, Macs, smartphones, tablets and anything else that mattered. The site today is just as strong in coverage of new mobile devices as it is in our traditional PC component coverage ... To the millions of readers who have visited and supported me and the site over the past 17+ years, I owe you my deepest gratitude. You all enabled me to spend over half of my life learning more than I ever could have in any other position. The education I've received doing this job and the ability to serve you all with it is the most amazing gift anyone could ever ask for. You enabled me to get the education of a lifetime and I will never be able to repay you for that. Thank you." -
Intel's Haswell-E Desktop CPU Debuts With Eight Cores, DDR4 Memory
crookedvulture writes: Intel has updated its high-end desktop platform with a new CPU-and-chipset combo. The Haswell-E processor has up to eight cores, 20MB of cache, and 40 lanes of PCI Express 3.0. It also sports a quad-channel memory controller primed for next-gen DDR4 modules. The companion X99 chipset adds a boatload of I/O, including 10 SATA ports, native USB 3.0 support, and provisions for M.2 and SATA Express storage devices. Thanks to the extra CPU cores, performance is much improved in multithreaded applications. Legacy comparisons, which include dozens of CPUs dating back to 2011, provide some interesting context for just how fast the new Core i7-5960X really is. Intel had to dial back the chip's clock speeds to accommodate the extra cores, though, and that concession can translate to slower gaming performance than Haswell CPUs with fewer, faster cores. Haswell-E looks like a clear win for applications that can exploit its prodigious CPU horsepower and I/O bandwidth, but it's clearly not the best CPU for everything. Reviews also available from Hot Hardware, PC Perspective, AnandTech, Tom's Hardware, and HardOCP. -
AMD Designing All-New CPU Cores For ARMv8, X86
crookedvulture (1866146) writes "AMD just revealed that it has two all-new CPU cores in the works. One will be compatible with the 64-bit ARMv8 instruction set, while the other is meant as an x86 replacement for the Bulldozer architecture and its descendants. Both cores have been designed from the ground up by a team led by Jim Keller, the lead architect behind AMD's K8 architecture. Keller worked at Apple on the A4 and A4 before returning to AMD in 2012. The first chips based on the new AMD cores are due in 2016." -
NVIDIA Launches GTX 750 Ti With New Maxwell Architecture
Vigile writes "NVIDIA is launching the GeForce GTX 750 Ti today, which would normally just be a passing mention for a new $150 mainstream graphics card. But company is using this as the starting point for its Maxwell architecture, which is actually pretty interesting. With a new GPU design that reorganizes the compute structure into smaller blocks, Maxwell is able to provide 66% more CUDA cores with a die size that is just 25% bigger than the previous generation all while continuing to use the same 28nm process technology we have today. Power and area efficiency were the target design points for Maxwell as it will eventually be integrated into NVIDIA's Tegra line, too. As a result the GeForce GTX 750 Ti is able to outperform AMD's Radeon R7 260X by 5-10% while using 35 watts less power at the same time." -
Asus Announces Small Form Factor 'Chromebox' PCs
MojoKid writes "Asus stepped out this morning with something new for the Chrome OS powered hardware crowd, called a "Chromebox" small form factor PC. Just as Google has been evangelizing with its Chromebook notebook initiative, the pitch for these Chromebox systems is that they're capable of doing everything you need to do in today's connected world. While not everyone will totally agree with that marketing pitch — gaming, 3D modeling, and a host of specialized tasks are better suited for a PC with higher specs — there's certainly a market for these types of devices. They're low cost, fairly well equipped, and able to handle a wide variety of daily computing chores. There are two SKUs being released in the U.S. The first starts at $179 and sports an Intel Celeron 2955U processor, and the second features an Intel Core i3 4010U CPU (no mention of price just yet), both of which are based on Intel's 4th generation Haswell CPU architecture. Beyond the processor, these fan-less boxes come with two SO-DIMM memory slots with 2GB or 4GB of DDR3-1600 RAM, a 16GB SSD, a GbE LAN port, 802.11n Wi-Fi, Bluetooth 4.0, 2-in-1 memory card reader, four USB 3.0 ports, HDMI output, a DisplayPort, an audio jack, and a Kensington Lock. ASUS also includes a VESA mount kit with each Chromebox, and Google tosses in 100GB of Google Drive space free for two years." -
AMD's Kaveri APU Debuts With GCN-based Radeon Graphics
crookedvulture writes "AMD's next-generation Kaveri APU is now available, and the first reviews have hit the web. The chip combines updated Steamroller CPU cores with integrated graphics based on the latest Radeon graphics cards. It's also infused with a dedicated TrueAudio DSP, a faster memory interface, and several features that fall under AMD's Heterogeneous System Architecture for mixed-mode computing. As expected, the APU's graphics performance is excellent; even the entry level, $119 A8-6700 is capable of playing Battlefield 4 at 1080p with medium detail settings. But the powerful GPU doesn't always translate to superior performance in OpenCL-accelerated applications, where comparable Intel chips are very competitive. Intel still has an advantage in power efficiency and raw CPU performance, too. Kaveri's CPU cores are certainly an improvement over the previous generation of Richland chips, but they can't match the per-thread throughput of Intel's rival Haswell CPU. In the end, Kaveri's appeal largely rests on whether the integrated graphics are fast enough for your needs. Serious gamers are better off with discrete GPUs, but more casual players can benefit from the extra Radeon horsepower. Eventually, HSA-enabled applications may benefit, as well." -
AMD's Radeon R9 290 Delivers 290X Performance For $150 Less
crookedvulture writes "The back and forth battle for PC graphics supremacy is quite a thing to behold. Last week, Nvidia cut GeForce prices in response to the arrival of AMD's latest Radeons. That move caused AMD to rejigger its plans for the new Radeon R9 290, which debuted today with a higher default fan speed and faster performance than originally planned. This $400 card offers almost identical performance to AMD's flagship R9 290X for $150 less. Indeed, it's often faster than Nvidia's $1000 GeForce Titan. But the 290 also consumes a lot more power, and its fan spins up to 49 decibels under load. Fortunately, the acoustic profile isn't too grating. Radeon R9 290 isn't the only new graphics card due this week, either. Nvidia is scheduled to unveil its GeForce GTX 780 Ti on November 7, and that card could further upset the balance at the high end of the GPU market. As AMD and Nvidia trade blows, PC gamers seem to be the ones who benefit." Additional reviews available from AnandTech, PC Perspective, Hot Hardware, and Tom's Hardware. -
Surface Pro 2 Gets Significant Battery Boost
SmartAboutThings writes "The original Surface Pro didn't have quite a good battery life and that's why Microsoft tried to fix this with the Surface Pro. After the Surface Pro 2 has hit general availability, Microsoft has silently pushed out a firmware update which, according to some new battery benchmarks run by Anandtech, made significant improvements to the battery life of the Surface Pro 2. After the new web browsing battery life test it was discovered that the Surface Pro 2 now manages better battery life than the ARM Surface 2, which is pretty impressive. With the firmware update, Microsoft was targeting over 8 hours, and AnadTech's benchmarks show Microsoft has succeeded, registering a 25% increase in battery life over the no-firmware version. The unpatched Surface Pro 2 lasted for 6.68 hours while with the firmware update installed, its battery life increased to 8.33 hours. The video playback test involved playing a movie until the battery died, and here, albeit smaller, improvements with the battery life have also been noticed: 7.73 hours compared to 6.65 hours." -
Why Does Windows Have Terrible Battery Life?
An anonymous reader writes "Jeff Atwood at Coding Horror is trying to figure out why the battery life for devices running Windows is so much worse than similar (or identical) devices running other operating systems. For example, the Surface Pro 2 made great strides over the original Surface Pro, increasing web-browsing battery life by 42%, but it still lags far behind Android and iOS tablets. The deficit doesn't get any better when Windows is run on Apple hardware. Atwood says, 'Microsoft positions Windows 8 as an operating system that's great for tablets, which are designed for casual web browsing and light app use – but how can that possibly be true when Windows idle power management is so much worse than the competition's desktop operating system in OS X – much less their tablet and phone operating system, iOS?' Anand Lal Shimpi is perplexed, too. Atwood is now reaching out to the community for answers: 'None of the PC vendors he spoke to could justify it, or produce a Windows box that managed similar battery life to OS X. And that battery life gap is worse today – even when using Microsoft's own hardware, designed in Microsoft's labs, running Microsoft's latest operating system released this week. Microsoft can no longer hand wave this vast difference away based on vague references to "poorly optimized third party drivers." ... I just wish somebody could explain to me and Anand why Windows is so awful at managing idle power.'" -
AMD's New Radeons Revisit Old Silicon, Enable Dormant Features
crookedvulture writes "The first reviews of AMD's Radeon R7 and R9 graphics cards have hit the web, revealing cards based on the same GPU technology used in the existing HD 7000 series. The R9 280X is basically a tweaked variant of the Radeon HD 7970 GHz priced at $300 instead of $400, while the R9 270X is a revised version of the Radeon HD 7870 for $200. Thanks largely to lower prices, the R9 models compare favorably to rival GeForce offerings, even if there's nothing exciting going on at the chip level. There's more intrigue with the Radeon R7 260X, which shares the same GPU silicon as the HD 7790 for only $140. Turns out that graphics chip has some secret functionality that's been exposed by the R7 260X, including advanced shaders, simplified multimonitor support, and a TrueAudio DSP block dedicated to audio processing. AMD's current drivers support the shaders and multimonitor mojo in the 7790 right now, and a future update promises to unlock the DSP. The R7 260X isn't nearly as appealing as the R9 cards, though. It's slower overall than not only GeForce 650 Ti Boost cards from Nvidia, but also AMD's own Radeon HD 7850 1GB. We're still waiting on the Radeon R9 290X, which will be the first graphics card based on AMD's next-gen Hawaii GPU." More reviews available from AnandTech, Hexus, Hot Hardware, and PC Perspective. -
How Many Android OEMs Cheat Benchmark Scores? Pretty Much All of Them
An anonymous reader writes "After Samsung got caught out cheating on benchmarks (Note 3, Galaxy S4) AnandTech has done a detailed analysis of the state of benchmark cheating amongst Android OEMs. With the exception of Motorola, literally every single OEM they've looked at ships (or has shipped) at least one device that does benchmark-specific CPU optimizations. AnandTech also thinks it will get worse before it gets better. 'The hilarious part of all of this is we’re still talking about small gains in performance. The impact on our CPU tests is 0 - 5%, and somewhere south of 10% on our GPU benchmarks as far as we can tell. I can't stress enough that it would be far less painful for the OEMs to just stop this nonsense and instead demand better performance/power efficiency from their silicon vendors.'
