A recent forum post at Beyond3D made an interesting claim: that the Samsung Galaxy S4's GPU ran at 532 MHz for certain whitelisted benchmark applications, and at 480 MHz for everything else. The folks at AnandTech decided to investigate and found out that the phone does indeed let its GPU run at a higher frequency when particular benchmark software is running. They found a similar oddity with the CPU — it wasn't restricted for other apps, but it was forced to run at max speed during benchmarks. Then they decided to look for direct evidence that this was intentional. "Poking around I came across the application changing the DVFS behavior to allow these frequency changes – TwDVFSApp.apk. Opening the file in a hex editor and looking at strings inside (or just running strings on the .odex file) pointed at what appeared to be hard coded profiles/exceptions for certain applications. The string 'BenchmarkBooster' is a particularly telling one. ... Quadrant standard, advanced, and professional, linpack (free, not paid), Benchmark Pi, and AnTuTu are all called out specifically. Nothing for GLBenchmark 2.5.1 though, despite its similar behavior."

edv writes "In a news posting dated 10th of September, Beyond3D is reporting of an article in a German publication in which id Software CEO Todd Hollenshead discusses the upcoming id title Rage and the engine it runs on, codenamed 'id Tech 5'. Amongst other things Todd mentions that no Linux version of the game is planned at the moment, and that it will run on Direct3D on Windows platform. OpenGL version is planned for the Mac however. If true, this would be a serious blow for Linux gaming (insert jokes here) as id and Carmack have been strong proponents of OpenGL and openness in the past."

GameDaily reports that the PlayStation Portable has an interesting restriction: its full processor power cannot be utilized at the same time as its WiFi functionality. Therefore, games that are played online cannot make use of the chip's 333mhz processor speed. The original finding from Beyond 3D was confirmed to GameDaily by Sony. Dave Karraker, Sr. Director, Corporate Communications: "The recent firmware upgrade (3.50) that removed the restriction on the PSP's CPU speed enables developers to utilize speeds either lower or higher than the default 222MHz, up to the full 333MHz clock speed. The article is correct that increased CPU speed cannot be used with the PSP's wireless feature." Though speculation is that this is a power-saving decision, there has been no official announcement as to the root cause.

Arun Demeure writes "Beyond3D has once again obtained new information on Intel's plans to compete against NVIDIA and AMD's graphics processors, in what the Chief Architect of the project presents as a 'battle for control of the computing platform.' He describes a new computing architecture based on the many-core paradigm with super-wide execution units, and the reasoning behind some of the design choices. Looks like computer scientists and software programmers everywhere will have to adapt to these new concepts, as there will be no silver bullet to achieve high efficiency on new and exotic architectures."

Arun Demeure writes "There have been rumors of Intel's re-entry into discrete graphics for months. Now Beyond3D reports that Intel has copped to the project on their own site. They describe it as a 'many-core' architecture aimed at 'high-end client platforms,' but also extending to other market segments in the future, with 'plans for accelerated CPU integration.' This might also encourage others to follow Intel's strategy of open-sourcing their Linux drivers. So, better watch out NVIDIA and AMD/ATI — there's new competition on the horizon."

Anyone Seen Thomas? writes "While Beyond3D's article on the ATI C1 (XENOS) graphics processor in the XBOX 360 gives you all you need to know about ATI's next generation hardware in terms of generating screen pixels, it also gives a big clue as to how it'll be useful for general purpose vector programming. XENOS is able to write data out of its unified memory architecture into system memory, and read it back again later. So with a large pool of powerful vector hardware available, does anyone fancy the idea of having a generalised , high-performance vector processor in their PC?. Read about that and the rest of XENOS." From the article: "Since XBOX 360's announcement and ATI's unleashing from the non disclosure agreements we've had the chance to not just chat with Robert Feldstein, VP of Engineering, but also Joe Cox, Director of Engineering overseeing the XBOX graphics design team, and two lead architects of the graphics processor, Clay Taylor and Mark Fowler. Here we hope to accurately impart a slightly deeper understanding of the XBOX 360 graphics processor, how it sits within the system, understand more about its operation as well as give some insights into the capabilities of the processor."

Duality writes "ATI has announced a new line of PCI Express 3D graphics boards dubbed the X850 Series. There are three new X850 cards being announced today, along with two new X800 cards. The X800 XL (16-pipelines) and X800 (12-pipelines) get a new core built on TSMC's .11 micron manufacturing process and don't require supplemental power. The flagship Radeon X850 XT Platinum Edition has been reviewed at HotHardware, and they've got more information on all of the other new Radeons as well. Prices for these new boards range from $249 all the way up to $549. (Other X850 Reviews: TR, Beyond3D, [H])"

Cryect writes "Earlier today it was announced by Creative that they would be adding in EAX 3D sound support to Doom 3, and that they had come to an 'agreement relating to Creative's patented shadowing technique [also known as Carmack's Reverse in some coding circles] and id's cutting-edge 3D graphics DOOM 3 engine.' This seemed somewhat suspicious, almost as if id was being pressured, and a quick email to John Carmack from Reverend @ Beyond3d got this reply: 'The patent situation well and truly sucks... It was tempting to take a stand and say that our products were never going to use any advanced Creative/3DLabs products because of their position on patenting gaming software algorithms, but that would only have hurt the users...' There's also some possible prior art [PPT link] to Creative Labs' patent, from a 1999 talk by Nvidia's Sim Dietrich."

An anonymous reader writes "Following the recent unveiling of Epic's Unreal Engine 3, Beyond3D has interviewed Tim Sweeney of Epic about the next-gen videogame engine. The discussion is mainly about the 3D requirements, but they also touch on other technologies that are used or required: 'Off-the-shelf 32-bit Windows can only tractably access 2GB of user RAM per process. UT2003, which shipped in 2002, installed more than 2GB of data for the game, though at that time it was never all loaded into memory at once. It doesn't exactly take a leap of faith to see scenarios in 2005-2006 where a single game level or visible scene will require >2GB RAM at full detail.'"

BudKnight writes "It looks like AMD is launching four new desktop processors, a new core, and a new socket infrastructure today. HotHardware has tested AMD's two new flagship processors, the Athlon 64 FX-53 and the Athlon 64 3800+. The new FX-53 no longer needs registered memory to function and the 3800+ has only 512K of cache, but it gets an upgraded 128-bit memory controller. The usual suspects also have reviews posted as well - TechReport, Hard|OCP, Beyond3D - more are sure to follow."

Dave Baumann writes "Beyond3D has put up an article based on Microsoft's games developers presentations given at Meltdown, looking at the future directions of MS's next generation DirectX - currently titled "DirectX Next" (DX10). With Pixel Shaders 2.0 and 3.0 already a part of DirectX9 this article gives a feel of what to expect from PS/VS4.0 and other DirectX features hardware developers will be expected to deliver with the likes of R500 and NV50."

Thanks to Blue's News for their post announcing that a playable demo of Remedy's PC third-person shooter Max Payne 2 has been released, with the 246 MB download featuring "the first three levels from the game, as well as a 'dead man walking' level that must be unlocked", and download sites including a BitTorrent link from 3DGamers. The well-received action title recently got a post-release interview over at Beyond3D, with project leader Markus Maki commenting on recent PC benchmarking controversy ("if a vendor can make the game run significantly faster with optimizations, without ruining the visual experience, I'm all for it"), and what they would have done with more time ("We're just scratching the surface of physics gameplay. With more development time, I'm sure our guys would've figured out a lot of cool stuff to do with them.")

cribb writes "3DMark 2003 is out, sparking an intense debate on how trustworthy its assessment of current graphics cards is, after some harsh words by nVidia and the reply from Futuremark. THG has an analysis of the current situation definately worth reading. The article exposes some problems with the new GeforceFX previously mentioned in a slashdot article on Doom3 and John Carmack. Alas, here seems to be no end to the troubles with the new nVidia flagship." If you've run the benchmark, post your scores here, and we'll all compare.
