AMD's R9 Fury On Open-Source: Prepare for Disappointment, For Now 36

An anonymous reader writes: With Linux 4.3 AMD is adding the initial open-source driver for the R9 Fury graphics cards. Unfortunate for Linux gamers, the R9 Fury isn't yet in good shape on the open-source driver and it's not good with the Catalyst Linux driver either as previously discussed. With the initial code going into Linux 4.3, the $550 R9 Fury runs slower than graphics cards like the lower-cost and older R7 370 and HD 7950 GPUs, since AMD's open-source developers haven't yet found the time to implement power management / re-clocking support. The R9 Fury also only advertises OpenGL 3.0 support while the hardware is GL4.5-capable and the other open-source AMD GCN driver ships OpenGL 4.1. It doesn't look like AMD has any near-term R9 Fury Linux fix for either driver, but at least their older hardware is performing well with the open-source code.

AMD Unveils Radeon R9 Nano, Targets Mini ITX Gaming Systems With a New Fury 59

MojoKid writes: AMD today added a third card to its new Fury line that's arguably the most intriguing of the bunch, the Radeon R9 Nano. True to its name, the Nano is a very compact card, though don't be fooled by its diminutive stature. Lurking inside this 6-inch graphics card is a Fiji GPU core built on a 28nm manufacturing process paired with 4GB of High Bandwidth Memory (HBM). It's a full 1.5 inches shorter than the standard Fury X, and unlike its liquid cooled sibling, there's no radiator and fan assembly to mount. The Fury Nano sports 64 compute units with 64 stream processors each for a total of 4,096 stream processors, just like Fury X. It also has an engine clock of up to 1,000MHz and pushes 8.19 TFLOPs of compute performance. That's within striking distance of the Fury X, which features a 1,050MHz engine clock at 8.6 TFLOPs. Ars Technica, too, takes a look at the new Nano.

NVIDIA Launches $159 Mainstream Maxwell-Based GeForce GTX 950 85

MojoKid writes: NVIDIA is launching a new mainstream graphics card today, the GeForce GTX 950, based on the company's GM206 GPU. The GM206 debuted on the GeForce GTX 960, which launched a few months back. As the new card's name suggests though, the GM206 used on the GeForce GTX 950 isn't quite as powerful as the one used on the GTX 960. The company is targeting this card at MOBA (massive online battle arena) players, who don't necessarily need the most powerful GPUs on the market, but want smooth, consistent framerates at resolutions of 1080p or below. It's being positioned as a significant, yet affordable, upgrade over cards like the GeForce GTX 650 Ti, that are a couple of generations old. NVIDIA's reference specifications for the GeForce GTX 950 call for a base clock of 1024MHz and a Boost clock of 1188MHz. The GPU is packing 768 CUDA cores, 48 texture units, and 32 ROPs. The 2GB of video memory on GeForce GTX 950 cards is clocked at a 6.6GHz (effective GDDR5 data rate) and the memory links to the GPU via a 128-bit interface. At those clocks, the GeForce GTX 950 offers up a peak textured fillrate of 49.2 GTexels/s and 105.6 GB/s of memory bandwidth. At a $159 starting MSRP, in the benchmarks, the GeForce GTX 950 offers solid entry level or midrange performance at 1080p resolutions. It's a bit faster than AMD's Radeon R9 270X but comes in just behind a Radeon R9 285.

AMD Still Struggling With Linux Gaming 100

An anonymous reader writes: AMD's Linux gaming performance has been embarrassingly bad, and it doesn't look like there's any quick remedy. Virtual Programming just released Dirt: Showdown for Linux, and it's the latest example of AMD's Linux driver issues: AMD's GPU results are still far behind NVIDIA's, with even the Radeon R9 Fury running slower than NVIDIA's aging GTX 680 and GTX 760. If a racing game doesn't interest you, Feral Interactive confirmed they are releasing Company of Heroes 2 for Linux next week, but only NVIDIA and Intel graphics are supported.

DirectX 12 Performance Tested In Ashes of the Singularity 96

Vigile writes: The future of graphics APIs lies in DirectX 12 and Vulkan, both built to target GPU hardware at a lower level than previously available. The advantages are better performance, better efficiency on all hardware and more control for the developer that is willing to put in the time and effort to understand the hardware in question. Until today we have only heard or seen theoretical "peak" performance claims of DX12 compared to DX11. PC Perspective just posted an article that uses a pre-beta version of Ashes of the Singularity, an upcoming RTS utilizing the Oxide Games Nitrous engine, to evaluate and compare DX12's performance claims and gains against DX11. In the story we find five different processor platforms tested with two different GPUs and two different resolutions. Results are interesting and show that DX12 levels the playing field for AMD, with its R9 390X gaining enough ground in DX12 to overcome a significant performance deficit that exists using DX11 to the GTX 980.

Dual GPU Battle: GTX 980 Ti SLI vs. Radeon R9 Fury X Crossfire 51

jjslash writes: High-end GPU parts from Nvidia and AMD are plenty fast, these days. While top-end cards from both can provide playable performance at 4K, many games dip down to and below 30fps. Folks looking to achieve smooth 4K gameplay will undoubtedly be eyeing dual GTX 980 Ti or Fury X cards to realize their PC gaming machine's full potential. TechSpot puts both cards to the test in SLI and Crossfire modes, at stock and overclocked speeds in over 10 games to see who gets the bragging rights. As it turns out, AMD has a tiny advantage in average frame rates. The two split wins on frame time, but AMD won by bigger margins. When the cards get overclocked, Nvidia is the clear winner, and power consumption favors Nvidia as well.

On Linux, $550 Radeon R9 Fury Competes With $200~350 NVIDIA GPUs 83

An anonymous reader writes: Earlier this month AMD released the air-cooled Radeon R9 Fury graphics card with Fury X-like performance, but the big caveat is the bold performance is only to be found on Windows. Testing the R9 Fury X on Linux revealed the Catalyst driver delivers devastatingly low performance for this graphics card. With OpenGL Linux games, the R9 Fury performed between the speed of a GeForce GTX 960 and 970, with the GTX 960 retailing for around $200 while the GTX 970 is $350. The only workloads where the AMD R9 Fury performed as expected under Linux was the Unigine Valley tech demo and OpenCL compute tests. There also is not any open-source driver support yet for the AMD R9 Fury.

AMD Starts Rolling Out New Linux Driver Model, But Many Issues Remain 61

An anonymous reader writes: With the upcoming Linux 4.2 kernel will be the premiere of the new "AMDGPU" kernel driver to succeed the "Radeon" DRM kernel driver, which is part of AMD's long talked about new Linux driver architecture for supporting the very latest GPUs and all future GPUs. Unfortunately for AMD customers, there's still much waiting. The new open-source AMDGPU Linux code works for Tonga/Carrizo GPUs but it doesn't yet support the latest R9 Fury "Fiji" GPUs, lacks re-clocking/DPM for Tonga GPUs leading to low performance, and there are stability issues under high-load OpenGL apps/games. There's also the matter that current Linux users need to jump through hoops for now in getting the code into a working state with the latest kernel and forked versions of Mesa, libdrm, new proprietary microcode files, and the new xf86-video-amdgpu user-space driver.

AMD Forces a LibreOffice Speed Boost With GPU Acceleration 144

New submitter samtuke writes: AMD processors get rated and reviewed based on performance. It is in our self-interest to make things work really, really fast on AMD hardware. AMD engineers contribute to LibreOffice, for good reason. Think about what happens behind a spreadsheet calculation. There can be a huge amount of math. Writing software to take advantage of a Graphics Processing Unit (GPU) for general purpose computing is non-trivial. We know how to do it. AMD engineers wrote OpenCL kernels, and contributed them to the open source code base. Turning on the OpenCL option to enable GPU Compute resulted in a 500X+ speedup, about ¼ second vs. 2minutes, 21 seconds. Those measurements specifically come from the ground-water use sample from this set of Libre Office spreadsheets.

AMD Catalyst Linux Driver Performs Wildly Different Based On Program's Name 114

An anonymous reader writes: In past years the AMD Catalyst Linux driver has yielded better performance if naming the executable "doom3.x86" or "compiz" (among other choices), but these days this application profile concept is made more absurd with more games coming to Linux but AMD not maintaining well their Linux application profile database. The latest example is by getting ~40% better performance by renaming Counter-Strike: Global Offensive on Linux. If renaming the "csgo_linux" binary to "hl2_linux" for Half-Life 2 within Steam, the frame-rates suddenly increase across the board, this is with the latest Catalyst 15.7 Linux driver while CS:GO has been on Linux for nearly one year. Should driver developers re-evaluate their optimization practices for Linux?

Air-Cooled AMD Radeon R9 Fury Arrives For $100 Less With Fury X-Like Performance 77

MojoKid writes: When AMD launched the liquid-cooled Radeon Fury X, it was obvious the was company willing to commit to new architecture and bleeding edge technologies (Fiji and High-Bandwidth Memory, respectively). However, it fell shy of the mark that enthusiasts hoped it would achieve, unable to quite deliver a definitive victory against NVIDIA's GeForce GTX 980 Ti. However, AMD just launched their Radeon R9 Fury (no "X" and sometimes referred to as "Fury Air"), a graphics card that brings a more compelling value proposition to the table. It's the Fury release that should give AMD a competitive edge against NVIDIA in the $500+ graphics card bracket. AMD's Radeon R9 Fury's basic specs are mostly identical to the liquid-cooled flagship Fury X, except for two important distinctions. There's a 50MHz reduction in GPU clock speed to 1000MHz, and 512 fewer stream processors for a total of 3584, versus what Fury X has on board. Here's the interesting news which the benchmark results demonstrate: In price the Fury veers closer to the NVIDIA GeForce GTX 980, but in performance it sneaks in awfully close to the GTX 980 Ti.

AMD's Latest Server Compute GPU Packs In 32GB of Memory 46

Deathspawner writes: Following-up on the release of 12GB and 16GB FirePro compute cards last fall, AMD has just announced a brand-new top-end: the 32GB FirePro S9170. Targeted at DGEMM computation, the S9170 sets a new record for GPU memory on a single card, and does so without a dual-GPU design. Architecturally, the S9170 is similar to the S9150, but is clocked a bit faster, and is set to cost about the same as well, at between $3,000~$4,000. While AMD's recent desktop Radeon launch might have left a bit to be desired, the company has proven with its S9170 that it's still able to push boundaries.

AMD's Project Quantum Gaming PC Contains Intel CPU 138

nateman1352 links to an article at Tom's Hardware which makes the interesting point that chip-maker AMD will offer Intel -- rather than AMD -- CPUs in their upcoming high-end gaming PC. (High-end for being based on integrated components, at least.) From the article: Recently, AMD showed off its plans for its Fiji based graphics products, among which was Project Quantum – a small form factor PC that packs not one, but two Fiji graphics processors. Since the announcement, KitGuru picked up on something, noticing that the system packs an Intel Core i7-4790K "Devil's Canyon" CPU. We hardly need to point out that it is rather intriguing to see AMD use its largest competitor's CPU in its own product, when AMD is a CPU maker itself.

AMD Radeon R9 Fury X Launched, Independent Benchmarks, HBM Put To the Test 103

MojoKid writes: AMD officially launched the Radeon R9 Fury X based on their next generation Fiji GPU and HBM 3D stacked DRAM memory. Fiji is manufactured using TSMC's 28nm process. At its reference clocks of 1050MHz (GPU) and 500MHz (HBM), Fiji and the Radeon R9 Fury X offer peak compute performance of 8.6 TFLOPs, up to 268.8 GT/s of texture fill-rate, 67.2 GP/s of pixel fill-rate, and a whopping 512GB/s of memory bandwidth, thanks to HBM. Its compute performance, memory bandwidth, and textured fill-rate are huge upgrades over the previous generation AMD Hawaii GPU and even outpace NVIDIA's GM200, which powers the GeForce Titan X and 980 Ti. To keep the entire assembly cool, AMD strapped a close-loop liquid cooler onto the Fury X. There's a reason AMD went that route on this card, and it's not because they had to. There will be air-cooled Fury and Fury Nano cards coming in a few weeks that feature fully-functional Fiji GPUs. What the high-powered liquid-cooler on the Fury X does is allow the use of an ultra-quiet fan, with the side benefit of keeping the GPU very cool under both idle and load conditions(around 60C max under load and 30C at idle), which helps reduce overall power consumption by limiting leakage current. The AMD Radeon R9 Fury X performed very well in the benchmarks, and remained competitive with a similarly priced, reference NVIDIA GeForce GTX 980 Ti, but it wasn't a clear win. Generally speaking, the Fury X was the faster of the two cards at 2560x1440. With the resolution cranked up to 3840x2160, however, the Fury X and 980 Ti trade victories.

AMD Reveals Radeon R9 Fury X Specs and Preliminary Benchmark Performance Results 87

MojoKid writes: AMD announced new Radeon R9 and R7 300 series of graphics cards earlier this week, and while they are interesting, they're not nearly as impressive as AMD's upcoming flagship of AMD GPU, code named Fiji. Fiji will find its way into three products this summer: the Radeon R9 Nano, Radeon R9 Fury, and the range-topping (and water-cooled) Radeon R9 Fury X. Other upcoming variants like, AMD's dual-Fiji board, were teased at E3 but are still under wraps. However, while full reviews are still under embargo, the official specification of the Radeon R9 Fury X have been revealed, along with an array of benchmark scores comparing the GPU to NVIDIA's GeForce GTX 980 Ti. Should the numbers AMD has released jibe with independent testing, the Radeon R9 Fury X looks strong and possibly faster than Nvidia's GeForce GTX 980 Ti.

AMD Announces Fiji-based Radeon R9 Fury X, 'Project Quantum', Radeon 300 Series 76

MojoKid writes: Today AMD announced new graphics solutions ranging from the bottom to the top ($99 on up to $649). First up is the new range of R7 300 Series cards that is aimed squarely at gamers AMD says are typically running at 1080p. For gamers that want a little bit more power, there's the new R9 300 Series (think of them as R9 280s with higher clocks and 8GB of memory). Finally, AMD unveiled its Fiji graphics cards that feature onboard High Bandwidth Memory (HBM), offering 3x the performance-per-watt of GDDR5. Fiji has 1.5x the performance-per-watt of the R9 290X, and was built with a focus on 4K gaming. The chip itself features 4096 stream processors and is comprised of 8.9 billion transistors. It has a graphics core clock of 1050MHz and is rated at 8.6 TFLOPs. AMD says there will also be plenty of overhead for overclocking. Finally, AMD also took the opportunity to showcase its "Project Quantum," which is a small form-factor PC that manages to cram two Fiji GPUs inside. The processor, GPUs, and all other hardware are incorporated into the bottom of the chassis, while the cooling solution is built into the top of the case.

AMD Radeon Fury and Fury X Specs Leaked, HBM-Powered Graphics On the Way 66

MojoKid writes: A fresh alleged leak of next AMD Fiji graphics info has just hit the web and there's an abundance of supposedly confirmed specifications for what will be AMD's most powerful graphics card to date. Fiji will initially be available in both Pro and XT variants with the Fiji Pro dubbed "Fury" and Fiji XT being dubbed "Fury X." The garden variety Fury touts single-precision floating point (SPFP) performance of 7.2 TFLOPS compared to 5.6 TFLOPS for a bone stock Radeon R9 290X. That's a roughly 29-percent performance improvement. The Fury X with its 4096 stream processors, 64 compute units, and 256 texture mapping units manages to deliver 8.6 TFLOPS, or a 54-percent increase over a Radeon R9 290X. The star of the show, however, will be AMD's High Bandwidth Memory (HBM) interface. Unlike traditional GDDR5 memory, HBM is stacked vertically, decreasing the PCB footprint required. It's also integrated directly into the same package as the GPU/SoC, leading to further efficiencies, reduced latency and a blistering 100GB/sec of bandwidth per stack (4 stacks per card). On average HBM is said to deliver three times the performance-per-watt of GDDR5 memory. With that being said, the specs listed are by no means confirmed by AMD, yet. We shall find out soon enough during AMD's E3 press conference scheduled for June 16.

Xilinx and AMD: an Inevitable Match? 108

itwbennett writes: Steve Casselman at Seeking Alpha was among the first to suggest that Xilinx should buy AMD because, among other reasons, it 'would let Xilinx get in on the x86 + FPGA fabric tsunami.' The trouble with this, however, is that 'AMD's server position is minuscule.... While x86 has 73% of the server market, Intel owns virtually all of it,' writes Andy Patrizio. At the same time, 'once Intel is in possession of the Altera product line, it will be able to cheaply produce the chip and drop the price, drastically undercutting Xilinx,' says Patrizio. And, he adds, buying AMD wouldn't give Xilinx the same sort of advantage 'since AMD is fabless.'
