AMD Withdraws From High-Density Server Business 123

Posted by samzenpus
from the stop-the-bleeding dept.
An anonymous reader sends word that AMD has pulled out of the market for high-density servers. "AMD has pulled out of the market for high-density servers, reversing a strategy it embarked on three years ago with its acquisition of SeaMicro. AMD delivered the news Thursday as it announced financial results for the quarter. Its revenue slumped 26 percent from this time last year to $1.03 billion, and its net loss increased to $180 million, the company said. AMD paid $334 million to buy SeaMicro, which developed a new type of high-density server aimed at large-scale cloud and Internet service providers."

itwbennett writes With AMD's fade out from the server market and the rapid decline of RISC systems, Intel has stood atop the server market all by itself. But now IBM, through its OpenPOWER Foundation, could give Intel and its server OEMs a real fight in China, which is a massive server market. As the investor group Motley Fool notes, OpenPOWER is a threat to Intel in the Chinese server market because the government has been actively pushing homegrown solutions over foreign technology, and many of the Foundation members, like Tyan, are from China.

Gaming On Linux With Newest AMD Catalyst Driver Remains Slow 178

Posted by samzenpus
from the molasses-in-the-winter dept.
An anonymous reader writes The AMD Catalyst binary graphics driver has made a lot of improvements over the years, but it seems that NVIDIA is still leading in the Linux game with their shared cross-platform driver. Tests done by Phoronix of the Catalyst 15.3 Linux Beta found on Ubuntu 15.04 shows that NVIDIA continues leading over AMD Catalyst with several different GPUs on BioShock Infinite, a game finally released for Linux last week. With BioShock Infinite on Linux, years old mid-range GeForce GPUs were clobbering the high-end Radeon R9 290 and other recent AMD GPUs tested. The poor showing wasn't limited to BS:I though as the Metro Redux games were re-tested too on the new drivers and found the NVIDIA graphics still ran significantly faster and certainly a different story than under Windows.

First AMD FreeSync Capable Gaming Displays and Drivers Launched, Tested 63

Posted by timothy
from the play-on-this dept.
MojoKid writes Soon after NVIDIA unveiled its G-SYNC technology, AMD announced that it would pursue an open standard, dubbed FreeSync, leveraging technologies already available in the DisplayPort specification to offer adaptive refresh rates to users of some discrete Radeon GPUs and AMD APUs. AMD's goal with FreeSync was to introduce a technology that offered similar end-user benefits to NVIDIA's G-SYNC, that didn't require monitor manufacturers to employ any proprietary add-ons, and that could be adopted by any GPU maker. Today, AMD released its first FreeSync capable set of drivers and this first look at the sleek ultra-widescreen LG 34UM67 showcases some of the benefits, based on an IPS panel with a native resolution of 2560x1080 and a max refresh rate of 75Hz. To fully appreciate how adaptive refresh rate technologies work, it's best to experience them in person. In short, the GPU scans a frame out to the monitor where it's drawn on-screen and the monitor doesn't update until a frame is done drawing. As soon as a frame is done, the monitor will update again as quickly as it can with the next frame, in lockstep with the GPU. This completely eliminates tearing and jitter issues that are common in PC gaming. Technologies like NVIDIA G-SYNC and AMD FreeSync aren't a panacea for all of PC gaming anomalies, but they do ultimately enhance the experience and are worthwhile upgrades in image quality and less eye strain.

AMD Enters Virtual Reality Fray With LiquidVR SDK At GDC 23

Posted by Soulskill
from the buzzword-ascending dept.
MojoKid writes: AMD jumped into the virtual reality arena today by announcing that its new LiquidVR SDK will help developers customize VR content for AMD hardware. "The upcoming LiquidVR SDK makes a number of technologies available which help address obstacles in content, comfort and compatibility that together take the industry a major step closer to true, life-like presence across all VR games, applications, and experiences," AMD representatives said in a statement. Oculus is one of the VR companies that will be working with AMD's LiquidVR SDK, and likes what it's seen so far. "Achieving presence in a virtual world continues to be one of the most important elements to delivering amazing VR," said Brendan Iribe, CEO of Oculus. "We're excited to have AMD working with us on their part of the latency equation, introducing support for new features like asynchronous timewarp and late latching, and compatibility improvements that ensure that Oculus' users have a great experience on AMD hardware."

AMD Unveils Carrizo APU With Excavator Core Architecture 114

Posted by Soulskill
from the trying-to-catch-up dept.
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.

New Encryption Method Fights Reverse Engineering 215

Posted by Soulskill
from the with-many-obfuscations,-all-bugs-are-deep dept.
New submitter Dharkfiber sends an article about the Hardened Anti-Reverse Engineering System (HARES), which is an encryption tool for software that doesn't allow the code to be decrypted until the last possible moment before it's executed. The purpose is to make applications as opaque as possible to malicious hackers trying to find vulnerabilities to exploit. It's likely to find work as an anti-piracy tool as well. To keep reverse engineering tools in the dark, HARES uses a hardware trick that’s possible with Intel and AMD chips called a Translation Lookaside Buffer (or TLB) Split. That TLB Split segregates the portion of a computer’s memory where a program stores its data from the portion where it stores its own code’s instructions. HARES keeps everything in that “instructions” portion of memory encrypted such that it can only be decrypted with a key that resides in the computer’s processor. (That means even sophisticated tricks like a “cold boot attack,” which literally freezes the data in a computer’s RAM, can’t pull the key out of memory.) When a common reverse engineering tool like IDA Pro reads the computer’s memory to find the program’s instructions, that TLB split redirects the reverse engineering tool to the section of memory that’s filled with encrypted, unreadable commands.

GeForce GTX 980 and 970 Cards From MSI, EVGA, and Zotac Reviewed 66

Posted by Soulskill
from the price-vs.-performance-vs.-really-loud-fans dept.
MojoKid writes: In all of its iterations, NVIDIA's Maxwell architecture has proven to be a good performing, power-efficient GPU thus far. At the high-end of the product stack is where some of the most interesting products reside, however. When NVIDIA launches a new high-end GPU, cards based on the company's reference design trickle out first, and then board partners follow up with custom solutions packing unique cooling hardware, higher clocks, and sometimes additional features. With the GeForce GTX 970 and GTX 980, NVIDIA's board partners were ready with custom solutions very quickly. These three custom GeForce cards, from enthusiast favorites EVGA, MSI, and Zotac represent optimization at the high-end of Maxwell. Two of the cards are GTX 980s: the MSI GTX 980 Gaming 4G and the Zotac GeForce GTX 980 AMP! Omgea, the third is a GTX 970 from EVGA, their GeForce GTX 970 FTW with ACX 2.0. Besides their crazy long names, all of these cards are custom solutions, that ship overclocked from the manufacturer. In testing, NVIDIA's GeForce GTX 980 was the fastest, single-GPU available. The custom, factory overclocked MSI and Zotac cards cemented that fact. Overall, thanks to a higher default GPU-clock, the MSI GTX 980 Gaming 4G was the best performing card. EVGA's GeForce GTX 970 FTW was also relatively strong, despite its alleged memory bug. Although, as expected, it couldn't quite catch the higher-end GeForce GTX 980s, but occasionally outpaced the AMD's top-end Radeon R9 290X.

Ask Slashdot: GPU of Choice For OpenCL On Linux? 110

Posted by timothy
from the discriminating-tastes dept.
Bram Stolk writes So, I am running GNU/Linux on a modern Haswell CPU, with an old Radeon HD5xxx from 2009. I'm pretty happy with the open source Gallium driver for 3D acceleration. But now I want to do some GPGPU development using OpenCL on this box, and the old GPU will no longer cut it. What do my fellow technophiles from Slashdot recommend as a replacement GPU? Go NVIDIA, go AMD, or just use the integrated Intel GPU instead? Bonus points for open sourced solutions. Performance not really important, but OpenCL driver maturity is.

GhostX9 writes: SLR Lounge just posted a first look at the Samsung NX1 28.1 MP interchangeable lens camera. They compare it to Canon and Sony full-frame sensors. Spoiler: The Samsung sensor seems to beat the Sony A7R sensor up to ISO 3200. They attribute this to Samsung's chip foundry. While Sony is using 180nm manufacturing (Intel Pentium III era) and Canon is still using 500nm process (AMD DX4 era), Samsung has gone with 65nm with copper interconnects (Intel Core 2 Duo — Conroe era). Furthermore, Samsung's premium lenses appear to be as sharp or sharper than Canon's L line and Sony's Zeiss line in the center, although the Canon 24-70/2.8L II is sharper at the edge of the frame.

AMD Catalyst Is the Broken Wheel For Linux Gaming 160

Posted by Soulskill
from the didn't-squeek-enough-to-get-the-grease dept.
An anonymous reader writes: Tests of the AMD Catalyst driver with the latest AAA Linux games/engines have shown what poor shape the proprietary Radeon driver currently is in for Linux gamers. Phoronix, which traditionally benchmarks with open-source OpenGL games and other long-standing tests, recently has taken specially interest in adapting some newer Steam-based titles for automated benchmarking. With last month's Linux release of Metro Last Light Redux and Metro 2033 Redux, NVIDIA's driver did great while AMD Catalyst was miserable. Catalyst 14.12 delivered extremely low performance and some major bottleneck with the Radeon R9 290 and other GPUs running slower than NVIDIA's midrange hardware. In Unreal Engine 4 Linux tests, the NVIDIA driver again was flawless but the same couldn't be said for AMD. Catalyst 14.12 wouldn't even run the Unreal Engine 4 demos on Linux with their latest generation hardware but only with the HD 6000 series. Tests last month also showed AMD's performance to be crippling for NVIDIA vs. AMD Civilization: Beyond Earth Linux benchmarks with the newest drivers.

AMD, Nvidia Reportedly Tripped Up On Process Shrinks 230

Posted by Soulskill
from the stupid-physics-getting-in-the-way dept.
itwbennett writes: In the fierce battle between CPU and GPU vendors, it's not just about speeds and feeds but also about process shrinks. Both Nvidia and AMD have had their move to 16nm and 20nm designs, respectively, hampered by the limited capacity of both nodes at manufacturer TSMC, according to the enthusiast site WCCFTech.com. While AMD's CPUs are produced by GlobalFoundaries, its GPUs are made at TSMC, as are Nvidia's chips. The problem is that TSMC only has so much capacity and Apple and Samsung have sucked up all that capacity. The only other manufacturer with 14nm capacity is Intel and there's no way Intel will sell them some capacity.

Phoronix Lauds AMD's Open Source Radeon Driver Progress For 2014 44

Posted by timothy
from the parity-looms dept.
Phoronix has taken an in-depth look at progress on AMD's open source Radeon driver, and declares 2014 to have been a good year. There are several pages with detailed benchmarks, but the upshot is overwhelmingly positive: Across the board there's huge performance improvements to find out of the open-source AMD Linux graphics driver when comparing the state at the end of 2013 to the current code at the end of this year. The performance improvements and new features presented (among them are OpenMAX / AMD video encode, UVD for older AMD GPUs, various new OpenGL extensions, continued work on OpenCL, power management improvements, and the start of open-source HSA) has been nothing short of incredible. Most of the new work benefits the Radeon HD 7000 series and newer (GCN) GPUs the most but these tests showed the Radeon HD 6000 series still improving too. ... Coming up before the end of the year will be a fresh comparison of these open-source Radeon driver results compared to the newest proprietary AMD Catalyst Linux graphics driver.

itwbennett writes According to a report in Korean IT Times, Samsung Electronics has begun production of the A9 processor, the next generation ARM-based CPU for iPhone and iPad. Korea IT Times says Samsung has production lines capable of FinFET process production (a cutting-edge design for semiconductors that many other manufacturers, including AMD, IBM and TSMC, are adopting) in Austin, Texas and Giheung, Korea, but production is only taking place in Austin. Samsung invested $3.9 billion in that plant specifically to make chips for Apple. So now Apple can say its CPU is "Made in America."

AMD Offers a Performance Boost, Over 20 New Features With Catalyst Omega Drivers 73

Posted by Soulskill
from the onward-and-upward dept.
MojoKid writes: AMD just dropped its new Catalyst Omega driver package that is the culmination of six months of development work. AMD Catalyst Omega reportedly brings over 20 new features and a wealth of bug fixes to the table, along with performance increases both on AMD Radeon GPUs and integrated AMD APUs. Some of the new functionality includes Virtual Super Resolution, or VSR. VSR is "game- and engine-agnostic" and renders content at up to 4K resolution, then displays it at a resolution that your monitor actually supports. AMD says VSR allows for increased image quality, similar in concept to Super Sampling Anti-Aliasing (SSAA). Another added perk of VSR is the ability to see more content on the screen at once. To take advantage of VSR, you'll need a Radeon R9 295X2, R9 290X, R9 290, or R9 285 discrete graphics card. Both single- and multi-GPU configurations are currently supported. VSR is essentially AMD's answer to NVIDIA's DSR, or Dynamic Super Resolution. In addition, AMD is claiming performance enhancements in a number of top titles with these these new drivers. Reportedly, as little as 6 percent improvement in performance in FIFA Online to as much as a 29 percent increase in Batman: Arkham Origins can be gained when using an AMD 7000-Series APU, for example. On discrete GPUs, an AMD Radeon R9 290X's performance increases ranged from 8 percent in Grid 2 to roughly 16 percent in Bioshock Infinity.

Dragon Age: Inquisition Reviewed and Benchmarked 91

Posted by samzenpus
from the to-play-or-not-to-play dept.
MojoKid writes To say that BioWare has something to prove with Dragon Age: Inquisition is an understatement. The first Dragon Age: Origins was a colossal, sprawling, unabashed throwback to classic RPGs. Conversely, Dragon Age: Inquisition doesn't just tell an epic story, it evolves in a way that leaves you, as the Inquisitor, leading an army. Creating that sense of scope required a fundamentally different approach to gameplay. Neither Dragon Origins or Dragon Age 2 had a true "open" world in the sense that Skyrim is an open world. Instead, players clicked on a location and auto-traveled across the map from Point A to Point B. Thus, a village might be contained within a single map, while a major city might have 10-12 different locations to explore. Inquisition keeps the concept of maps as opposed to a completely open world, but it blows those maps up to gargantuan sizes. Instead of simply consisting of a single town or a bit of wilderness, the new maps in Dragon Age: Inquisition are chock-full of areas to explore, side quests, crafting materials to gather, and caves, dungeons, mountain peaks, flowing rivers, and roving bands of monsters. And Inquisition doesn't forget the small stuff — the companion quests, the fleshed-out NPCs, or the rich storytelling — it just seeks to put those events in a much larger context across a broad geographical area. Dragon Age: Inquisition is one of the best RPGs to come along in a long time. Never has a game tried to straddle both the large-scale, 10,000-foot master plan and the small-scale, intimate adventure and hit both so well. In terms of graphics performance, you might be surprised to learn that a Radeon R9 290X has better frame delivery than a GeForce GTX 980, despite the similarity in the overall frame rate. The worst frame time for an Radeon R9 290X is just 38.5ms or 26 FPS while a GeForce GTX 980 is at 46.7ms or 21 FPS. AMD takes home an overall win in Dragon Age: Inquisition currently, though Mantle support isn't really ready for prime time. In related news, hypnosec sends word that Chinese hackers claim to have cracked Denuvo DRM, the anti-piracy solution for Dragon Age: Inquisition. A Chinese hacker group has claimed that they have managed to crack Denuvo DRM — the latest anti-piracy measure to protect PC games from piracy. Introduced for the first time in FIFA 15 for PC, the Denuvo anti-piracy solution managed to keep the FIFA 15 uncracked for 2 months and Dragon Age Inquisition for a month. However, Chinese hackers claim that they have managed to rip open the DRM after fifteen days of work. The hackers have uploaded a video to prove their accomplishment. A couple of things need to be pointed out here. First,the Chinese team has merely cracked the DRM and this doesn't necessarily mean that there are working cracks out there. Also, the crack only works with Windows 7 64-bit systems and won't work on Windows 8 or Windows 7 32-bit systems for now. The team is currently working to collect hardware data on processor identification codes.

An Applied Investigation Into Graphics Card Coil Whine 111

Posted by timothy
from the like-y'do dept.
jones_supa writes We all are aware of various chirping and whining sounds that electronics can produce. Modern graphics cards often suffer from these kind of problems in form of coil whine. But how widespread is it really? Hardware Canucks put 50 new graphics cards side-by-side to compare them solely from the perspective of subjective acoustic disturbance. NVIDIA's reference platforms tended to be quite well behaved, just like their board partners' custom designs. The same can't be said about AMD since their reference R9 290X and R9 290 should be avoided if you're at all concerned about squealing or any other odd noise a GPU can make. However the custom Radeon-branded SKUs should usually be a safe choice. While the amount and intensity of coil whine largely seems to boil down to luck of the draw, at least most board partners are quite friendly regarding their return policies concerning it.
