Overclocker Pushes Intel Core i7-7700K Past 7GHz Using Liquid Nitrogen (hothardware.com)
MojoKid writes from a report via HotHardware: If you've had any doubts of Intel's upcoming Kaby Lake processor's capabilities with respect to overclocking, don't fret. It's looking like even the most dedicated overclockers are going to have a blast with this series. Someone recently got a hold of an Intel Core i7-7700K chip and decided to take it for an overclocking spin. Interestingly, the motherboard used is not one of the upcoming series designed for Kaby Lake, but the chip was instead overclocked on a Z170 motherboard from ASRock (Z170M OC Formula). That bodes well for those planning to snag a Kaby Lake CPU and would rather not have to upgrade their motherboard as well. With liquid nitrogen cooling the processor, this particular chip peaked at just over 7GHz, which helped deliver a SuperPi 32M time of 4m 20s, and a wPrime 1024M time of 1m 33s. It's encouraging to see the chip breaking this clock speed, even with extreme methods, since it's a potential relative indicator of how much headroom will be available for overclocking with more standard cooling solutions. -
MSI and ASUS Accused of Sending Reviewers Overpowered Graphics Cards (theverge.com)
An anonymous reader writes from a report via The Verge: TechPowerUp discovered that the MSI GeForce GTX 1080 Gaming X card they were sent for review was running at faster GPU and memory clock speeds than the retail version. This was because the review card was set to operate in the OC (overclocking) mode out of the box, whereas the retail card runs in the more regular Gaming mode out of the box. This may result in an unobservant reviewer accidentally misrepresenting the OC performance numbers as the stock results from the card, lending MSI's product an unearned helping hand. The site found this was a recurring pattern with MSI stretching back for years. Fellow Taiwanese manufacturer ASUS, in spite of having better global name recognition and reputation, has also show itself guilty of preprogramming review cards with an extra overclocking boost. Needless to say, the only goal of such actions is to deceive -- both the consumer and the reviewer -- though perhaps some companies have felt compelled to follow suit after the trend was identified among competitors. The Verge notes that TechPowerUp revealed its finding on Thursday of last week, and has not received any official response from either MSI or ASUS. They did update their story to note that MSI addressed the matter, in a comment provided to HardOCP Editor-in-Chief Kyle Bennett, back in 2014. -
SSD Manufacturer OCZ Preparing For Bankruptcy
JDG1980 writes "OCZ, a manufacturer of solid-state drives, says it will file for bankruptcy. This move is being forced by Hercules Technology Growth Capital, which had lent $30 million to OCZ under terms that were later breached. The most likely outcome of this bankruptcy is that OCZ's assets (including the Indilinx controller IP) will be purchased by Toshiba. If this deal falls through, the company will be liquidated. No word yet on what a Toshiba purchase would mean in terms of warranty support for OCZ's notoriously unreliable drives." -
Toward An FSF-Endorsable Embedded Processor
lkcl writes about his effort to go further than others have, and actually have a processor designed for Free Software manufactured: "A new processor is being put together — one that is FSF Endorseable, contains no proprietary hardware engines, yet an 800MHz 8-core version would, at 38 GFLOPS, be powerful enough on raw GFLOPS performance figures to take on the 3ghz AMD Phenom II x4 940, the 3GHz Intel i7 920 and other respectable mid-range 100 Watt CPUs. The difference is: power consumption in 40nm for an 8-core version would be under 3 watts. The core design has been proven in 65nm, and is based on a hybrid approach, with its general-purpose instruction set being designed from the ground up to help accelerate 3D Graphics and Video Encode and Decode, an 8-core 800mhz version would be capable of 1080p30 H.264 decode, and have peak 3D rates of 320 million triangles/sec and a peak fill rate of 1600 million pixels/sec. The unusual step in the processor world is being taken to solicit input from the Free Software Community at large before going ahead with putting the chip together. So have at it: if given carte blanche, what interfaces and what features would you like an FSF-Endorseable mass-volume processor to have? (Please don't say 'DRM' or 'built-in spyware')." There's some discussion on arm-netbook. This is the guy behind the first EOMA-68 card (currently nearing production). As a heads ups, we'll be interviewing him in a live style similarly to Woz (although intentionally this time) next Tuesday. -
CPU Competition Heating Up In 2012?
jd writes "2012 promises to be a fun year for hardware geeks, with three new 'Aptiv-class' MIPS64 cores being circulated in soft form, a quad-core ARM A15, a Samsung ARM A9 variant, a seriously beefed-up 8-core Intel Itanium and AMD's mobile processors. There's a mix here of chips actually out, ready to be put on silicon, and in last stages of development. Obviously these are for different users (mobile CPUs don't generally fight for marketshare with Itanium dragsters) but it is still fascinating to see the differences in approach and the different visions of what is important in a modern CPU. Combine this with the news reported earlier on DDR4, and this promises to be a fun year with many new machines likely to appear that are radically different from the last generation. Which leaves just one question — which Linux architecture will be fully updated first?" -
AMD Downgrades Bulldozer Transistor Count By 800 Million
Robadob writes "It has come to light that AMD PR had originally reported that the new Bulldozer processor's transistor count was 2 billion. AMD PR are now asking reviewers to correct this count to 1.2 billion from the original amount they provided ~3 months ago." -
AMD Radeon HD 6950 Can Be Unlocked To HD 6970
An anonymous reader writes "AMD's new Radeon HD 6950 can be unlocked to a HD 6970 via BIOS mod. Performance of the unlocked card is identical to the full blown HD 6970!" -
ASUS Designs Monster Dual-GTX285 4GB Graphics Card
suraj.sun writes to mention that ASUS has just designed their own monster graphics card based on the GeForce GTX 295. While the card retains the GeForce GTX 295 name, same device ID, and remains compatible with existing NVIDIA drivers, ASUS has made a couple of modifications to call its own. "the company used two G200-350-B3 graphics processors, the same ones that make the GeForce GTX 285. The GPUs have all the 240 shader processors enabled, and also have the complete 512-bit GDDR3 memory interface enabled. This dual-PCB monstrosity holds 32 memory chips, and 4 GB of total memory (each GPU accesses 2 GB of it). Apart from these, each GPU system uses the same exact clock speeds as the GeForce GTX 285: 648/1476/2400 MHz (core/shader/memory)."
