How OpenGL Graphics Card Performance Has Evolved Over 10 Years (phoronix.com) 115

An anonymous reader writes: A new report at Phoronix looks at the OpenGL performance of 27 graphics cards from the GeForce 8 through GeForce 900 series. Various Ubuntu OpenGL games were tested on these graphics cards dating back to 2006, focusing on raw performance and power efficiency. From oldest to newest, there was a 72x increase in performance-per-Watt, and a 100x increase in raw performance. The NVIDIA Linux results arrive after doing a similar AMD comparison from R600 graphics cards through the R9 Fury. However, that analysis found that for many of the older graphics cards, their open-source driver support regressed into an unworkable state. For the cards that did work, the performance gains were not nearly as significant over time.

AMD Rips 'Biased and Unreliable' Intel-Optimized SYSmark Benchmark (hothardware.com) 174

MojoKid writes: AMD is making a stink about SYSMark, a popular benchmarking program that's been around for many years, and one the chip designer says is not reliable. Rather than provide meaningful results and information, AMD claims SYSMark unfairly favors Intel products and puts too much emphasis on strict CPU performance above all else. John Hampton, director of AMD's client computing products, explained in a video why SYSMark itself is an unreliable metric of performance. He even brought up the "recent debacle" involving Volkswagen as proof that "information provided by even the most established organizations can be misleading." Salinas says SYSMark's focus on the CPU is so "excessive" that it's really only evaluating the processor, not the system as a whole. In comparison, PCMark 8 probes not only the CPU, but graphics and subsystems as well. In an attempt to drive the point home, AMD ran a set of custom scripts it developed based on Microsoft Office and timed how long it took each system to complete them. The Intel system took 61 seconds to finish the benchmark versus 64 seconds for the AMD platform, a difference of about 6-7 percent and in line with what PCMark 8 indicated, though Sysmark shows a stark delta of 50 percent in favor of Intel with comparable CPUs.

Open Source Could Help Bring Vulkan To More AMD GPUs (phoronix.com) 38

An anonymous reader writes: AMD has confirmed that their Vulkan Linux driver will only work with the new AMDGPU kernel driver, meaning that for right now on the desktop, Vulkan will just work on the Radeon R9 285, R9 380, R9 380X and R9 Fury series — not even the other Rx 200/300 series graphics cards. This limitation exists because the AMDGPU driver only works with GCN 1.2 and newer. In time, AMD may allow the driver to work on older GCN GPUs going back to the HD 7000 series. But wait: AMDGPU is open-source. AMD is welcoming community support to help bring AMDGPU (and thereby Vulkan) to these older GPUs. The work involved would be porting GCN 1.0/1.1 support from the existing open-source Radeon DRM driver over to the new AMDGPU DRM driver. The Vulkan code itself is said to already be compatible with all GCN GPUs going back to the HD 7xxx series.

Microsoft: Only the Latest Version of Windows Will Support New CPU Generations (windows.com) 458

Joe_Dragon sends news from Microsoft about how the company will support Windows now and in the future. The company says PCs built with Intel's Skylake chip, and other new architectures in the future, will require the latest version of Windows for support. This doesn't take effect right away; Windows 7 and 8.1 will be supported on older chips until their planned end-of-life dates, in 2020 and 2023 respectively. They'll also be supported on a list of current Skylake devices for the next 18 months. After that, only the latest version of Windows will support integration between the operating system and new CPU features. "For example, Windows 10 will be the only supported Windows platform on Intel's upcoming 'Kaby Lake' silicon, Qualcomm's upcoming '8996' silicon, and AMD's upcoming 'Bristol Ridge' silicon." Microsoft also mentioned that for new supported systems, the company will "ensure all drivers will be on Windows Update with published BIOS/UEFI upgrading tools." The submitter adds, "Putting BIOS/UEFI updates in to the Windows 10 auto- / forced-update system may open Microsoft to paying $600-$1,000+ to replace broken laptops. If Windows tries to update BIOS/UEFI at a bad/risky time (like during power instability in a big storm), it could lead to an update loop or worse."

AMD Unveils 64-Bit ARM-Based Opteron A1100 System On Chip With Integrated 10GbE (hothardware.com) 98

MojoKid writes: AMD is adding a new family of Opterons to its enterprise processor line-up today called the Opteron A1100 series. Unlike AMD's previous enterprise offerings, however, these new additions are packing ARM-based processor cores, not the X86 cores AMD has been producing for years. The Opteron A1100 series is designed for a variety of use cases and applications, including networking, storage, dense and power-efficient web serving, and 64-bit ARM software development. The new family was formerly codenamed "Seattle" and it represents the first 64-bit ARM Cortex-A57-based platform from AMD. AMD Opteron A1100 Series chips will pack up to eight 64-bit ARM Cortex-A57 cores with up to 4MB of shared Level 2 and 8MB of shared Level 3 cache. They offer two 64-bit DDR3/DDR4 memory channels supporting speeds up to 1866 MHz with ECC and capacities up to 128GB, dual integrated 10Gb Ethernet network connections, 8-lanes of PCI-Express Gen 3 connectivity, and 14 SATA III ports. AMD is shipping to a number of software and hardware partners now with development systems already available.

Mesa's Highlights Reel: An Impressive Year For Open Source 3-D Drivers 27

Michael Larabel at Phoronix has been assiduously reporting on some of the small advancements in open source 3-D graphics; in aggregate, those small advancements make for big improvements in hardware (and platform) support, as well as higher performance. Phoronix published today a year-end wrap-up highlighting some of the ways that Mesa has developed; it's quite a list. An excerpt: This time last year core Mesa and the drivers were still limited to OpenGL 3.3 compliance while in 2015 we've seen core Mesa reach up to OpenGL 4.2 support. The AMD RadeonSI and R600g drivers have raised up through OpenGL 4.1 (though R600g is limited in what supports GL4) and the Nouveau NVC0 driver is at OpenGL 4.1 as well. The Intel Mesa driver is still at OpenGL 3.3, but they are extremely close to OpenGL 4.2 and should hit that milestone in early 2016 after having been recently focusing up on OpenGL ES 3.1 support, which they did achieve this year. Besides tackling more GL4 support, Mesa this year has seen the new VirtIO GPU driver for 3D support in guest VMs, continued work on the new Raspberry Pi 3D driver (VC4), video encode/decode improvements, and other Gallium3D state tracker highlights.

AMD Goes Open Source, Announces GPUOpen Initiative, Linux Compiler, Drivers (hothardware.com) 89

MojoKid writes: AMD announced today that the company is releasing a slew of open-source software and tools to give game developers, heterogeneous applications, and HPC applications deeper access to the GPU and GPU resources. AMD and their Radeon Technologies Group (RTG) are looking for ways to ease game development, so developers can more easily re-use code and port their games from consoles over to the PC. With GPUOpen, game developers will have direct access to GPU hardware, as well as access to a large collection of open source effects, tools, libraries and SDKs, which are being made available on GitHub under an MIT open-source license. As part of the effort, the company is also releasing a new HCC C++ compiler which will be a tool in enabling developers to more easily leverage the resources of discrete GPU hardware in heterogeneous systems. The HCC complier also allows developers to convert CUDA code to portable C++. According to AMD, internal testing shows that in many cases 90 percent or more of CUDA code can be automatically converted into C++ with the final 10 percent converted manually in the widely popular C++ language. An early access program for the "Boltzmann Initiative" tools is planned for Q1 2016.

The Ups and Downs of AMD (hackaday.com) 225

szczys writes: In 2003 AMD was on top of the world. Now they're not, but they're also still in business. AMD continues to produce inexpensive, well-engineered semiconductors. The fall over the last 10 years is due to Intel, who used illegal practices and ethically questionable engineering decisions to knock AMD off their roost while still keeping them in business. The latter prevents the finger of antitrust from being pointed at Intel the way it was for Ma Bell.

Radeon Graphics Cards To Support HDR Displays and FreeSync Over HDMI In 2016 (hothardware.com) 37

MojoKid writes: AMD's Radeon Technologies Group has announced a couple of new features for Radeon graphics support in 2016. FreeSync over HDMI support will be coming to all Radeons that currently support FreeSync. FreeSync over HDMI, however, will require new displays. The HDMI specification doesn't currently have support for variable refresh rates, but it does allow for vendor specific extensions. Radeon Technologies Group is using these vendor specific extensions to enable the technology. A number of FreeSync over HDMI compatible displays are slated to arrive early next year from brands including LG, Acer, and Samsung. The first notebook with FreeSync has also launched. Lenovo's Y700 gaming notebook is the first with a validated, FreeSync-compatible panel. The Radeon Technologies Group also announced that support for DisplayPort 1.3, HDMI 2.0a and HDR displays was coming in the 2016 pipeline as well. With current 8-bit panels, the range of colors, contrast, and brightness presented to users is only a fraction of what the human eye can see. When source material is properly mapped to an HDR panel, colors are more accurately displayed representing more closely what the human eye would see in the real world.

Microsoft To Open Source Chakra, the JavaScript Engine In Its Edge Browser (windows.com) 114

An anonymous reader writes: Microsoft announced today that it will soon open source the "Chakra" JavaScript engine used inside its Edge browser and Internet Explorer. The company plans to publish the code on its GitHub page in January. "Microsoft is calling the version it's open sourcing ChakraCore. This is the complete JavaScript engine—the parser, the interpreter, the just-in-time compiler, and the garbage collector along with the API used to embed the engine into applications (as used in Edge). This will have the same performance and capabilities, including asm.js and SIMD support, as well as cutting-edge support for new ECMAScript 2015 language features like the version found in Microsoft's Windows 10 browser." While it'll be Windows-only code to start, they plan on taking it cross-platform just as they did with .NET. "Microsoft intends to run ChakraCore's development as a proper community project. The company says that Intel and AMD have already expressed interest in contributing, and others are sure to join them."

AMD's 'Crimson' Driver Software Released (anandtech.com) 50

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."

Windows 10 Fall Update Uninstalls Desktop Software Without Informing Users (ghacks.net) 360

ourlovecanlastforeve sends this report from Martin Brinkmann of gHacks: Microsoft's Windows 10 operating system may uninstall programs — desktop programs that is — from the computer after installation of the big Fall update that the company released earlier this month. I noticed the issue on one PC that I upgraded to Windows 10 Version 1511 but not on other machines. The affected PC had Speccy, a hardware information program, installed and Windows 10 notified me after the upgrade that the software had been removed from the system because of incompatibilities. There was no indication beforehand that something like this would happen, and what made this rather puzzling was the fact that a newly downloaded copy of Speccy would install and run fine on the upgraded system. An IT Director I know had this happen with ESET antivirus as well, on multiple computers. He says fixes have been rolled out for both TH2 and the antivirus software to prevent this from happening. Other reports mention CPU-Z, AMD's Catalyst Control Center, and CPUID as software that's being automatically uninstalled.

AMD Launches Radeon R9 380X, Fastest GPU Under $250 (hothardware.com) 110

MojoKid writes: Although AMD's mid-range GPU line-up has been relatively strong for a while now, the company is launching the new Radeon R9 380X today with the goal of taking down competing graphics cards like NVIDIA's popular GeForce GTX 960. The Radeon R9 380X has a fully-functional AMD Tonga GPU with all 32 compute units / 2048 shader processors enabled. AMD's reference specifications call for 970MHz+ engine clock with 4GB of 1425MHz GDDR5 memory (5.7 Gbps effective). Typical board power is 190W and cards require a pair of supplemental 6-pin power feeds. The vast majority of the Radeon R9 380X cards that will hit the market, however, will likely be custom models that are factory overlcocked and look nothing like AMD's reference design. The Radeon R9 380X, or more specifically the factory overclocked Sapphire Nitro R9 380X tested, performed significantly better than AMD's Radeon R9 285 or NVIDIA's GeForce GTX 960 across the board. The 380X, however, could not catch more powerful and more expensive cards like the GeForce GTX 970. Regardless, the Radeon R9 380X is easily the fastest graphics card on the market right now, under $250.

NVIDIA Jetson TX1 Performance Shines For GPU Computing (phoronix.com) 22

An anonymous reader writes: Following last week's announcement of the Jetson TX1 development board, NVIDIA is now allowing independent reports of performance for their $599 USD 64-bit ARM development board. Linux results published by Phoronix show very strong performance for the Jetson TX1 when looking at the Cortex-A57 speed relative to the Tegra K1 and older Tegra SoCs along with other ARM hardware like Calxeda and Raspberry Pi. The Jetson TX1 was generally multiple times faster than ARM hardware a few years old. The graphics performance was twice as fast as the year-old Jetson TK1 thanks to the Maxwell GPU. Compared to x86 hardware, in CPU-bound tasks the performance is comparable to an AMD Sempron/Phenom except when utilizing GPGPU computing where it's then faster than Intel Skylake and Xeon processors. The Jetson TX1 had a peak power consumption of 16 Watts and an average power use of under 10 Watts.

AMD Sued Over Allegedly Misleading Bulldozer Core Count 311

An anonymous reader writes: A class action suit accuses AMD of misleading buyers about the number of cores in its Bulldozer-based CPUs. The complaint claims that the chips effectively had only four cores, while AMD claims there are eight. According to Ars: "AMD's multi-core Bulldozer chips use a unique design that combines the functions of what would normally be two discrete cores into a single package, which the company calls a module. Each module is identified as two separate cores in Windows, but the cores share a single floating point unit and instruction and execution resources. This is different from Intel's cores, which feature independent FPUs. The suit claims that Bulldozer's design means its cores cannot work independently, and as a result, cannot perform eight instructions simultaneously and independently. This, the claim continues, results in performance degradation, and average consumers in the market for a CPU lack the technical expertise to understand the design of AMD's processors and trust the company to give accurate specifications regarding its CPUs."

AMD To Retire Catalyst Control Center Drivers, Rolling Out New Crimson Platform (hothardware.com) 113

MojoKid writes: AMD has gone through significant changes as a company over the last few months. Recently, we've seen them enter into a joint venture with Nantong Fujitsu for final assembly and test operations. They've also formed the new Radeon Technologies Group, led by longtime graphics guru Raja Koduri. Today, AMD is announcing another big change, and this one affects a piece of software that you may have running on your systems right now, if there's a Radeon graphics card on board. AMD is ditching Catalyst Control Center in favor of software dubbed Radeon Settings, which is a critical part of what AMD is calling the Radeon Software Crimson Edition. Radeon Software Crimson Edition is completely re-architected and is claimed to offer new features, improvements to stability and responsiveness, and performance improvements as well. The update will include a new Game Manager, video quality presets, social media integration, simplified EF setup, a system notifications tab, and more. It looks as though the first version of the software will be out this month.

Open-Source GPU Drivers Show Less Than Ideal Experience For SteamOS/Linux Gaming (phoronix.com) 109

An anonymous reader writes: Phoronix's recent 22-Way SteamOS Graphics Card Comparison showed that NVIDIA wins across the board when it comes to closed-source OpenGL driver performance. However, when it comes to the open-source driver performance for Steam Linux gaming, no one is really the winner. A new article, "Are The Open-Source Graphics Drivers Good Enough For Steam Linux Gaming?" answers that question with "heck no" by its author. While AMD is generally regarded as having better open-source support, their newer graphics cards still can't run at their rated clock frequencies due to lack of power management support, the lack of enough OpenGL 4.x support means many AAA Linux games simply cannot run yet, not enough QA means regressions are common, and other issues were noted when it comes to testing a number of modern graphics cards on the open-source drivers.
