Benchmarking Radeon Open Compute ROCm 1.4 OpenCL

Filed under
Graphics/Benchmarks

Last month with AMD/GPUOpen's ROCm 1.4 release they delivered on OpenCL support, albeit for this initial release all of the code is not yet open-source. I tried out ROCm 1.4 with the currently supported GPUs to see how the OpenCL performance compares to just using the AMDGPU-PRO OpenCL implementation.

RADV Improved

  • RADV Vulkan Driver Support For Multiple Devices

    Open-source driver developer Bas Nieuwenhuizen has posted a patch for allowing the open-source Radeon Mesa Vulkan driver (RADV) to support multiple devices.

  • The open source Vulkan driver for AMD 'radv' now supports using multiple GPUs

    A commit that just landed in Mesa-git allows for 'radv', the open source Vulkan driver for AMD GPUs to use multiple devices.

    This will likely be useful in future for people who have two (or maybe even more) GPUs to really push their games.

    Support for things like that on Linux should improve as Vulkan evolves and is adopted by more developers. Just how useful this will end up being is the real question.

A Look At The Huge Performance Boosts With Nouveau Mesa 17.0-devel On Maxwell

Filed under
Graphics/Benchmarks

Landing this week in Mesa 17.0-devel Git was OpenGL 4.3 for NVC0 Maxwell and a big performance boost as well for these GeForce GTX 750 / 900 series NVIDIA "Maxwell" graphics processors. Here are some before/after benchmarks of the performance improvements, which the patch cited as "1.5~3.5x better", when testing a GeForce GTX 750 Ti and GTX 980.

  • Etnaviv Gallium3D Driver Lands, Premiering With Mesa 17.0

    In time for this weekend's feature freeze of Mesa 17.0, the Etnaviv Gallium3D driver has landed in Mesa Git after years of work on this reverse-engineered, open-source driver stack.

  • Intel ANV Vulkan Driver Lands Last Minute HiZ Improvements

    Some more exciting last minute work landing in Mesa Git before this weekend's Mesa 17.0 branching are the potentially performance-improving HiZ work within the Intel Vulkan driver.

  • Google releases 'Draco' 3D graphics open source compression library on GitHub

    Google is a significant contributor to the open source community. This is notable, as the company is wildly successful and its products are used by many. It incorporates open source code in its offerings, and then contributes back too. The search giant's visibility lends credibility to open source ideology.

    Today, Google announces yet another open source project. Called "Draco," it is a compression library designed for 3D graphics. The project can dramatically reduce the size of 3D graphic files without significant visual impact to the person viewing.

  • Introducing Draco: compression for 3D graphics

    3D graphics are a fundamental part of many applications, including gaming, design and data visualization. As graphics processors and creation tools continue to improve, larger and more complex 3D models will become commonplace and help fuel new applications in immersive virtual reality (VR) and augmented reality (AR). Because of this increased model complexity, storage and bandwidth requirements are forced to keep pace with the explosion of 3D data.

  • Google Announces "Draco" For 3D Graphics Compression

    Google's Chrome Media team has developed Draco as an open-source compression library designed for 3D graphics.

  • Fedora 25 Switching Over To Using GLVND For Mesa, Happier NVIDIA Driver Installation

    A Mesa update coming down the pipe for Fedora 25 Linux users will see GLVND support enabled by default.

    GLVND, of course, being the OpenGL Vendor Neutral Dispatch library. This is the NVIDIA-led effort that was also supported by upstream Mesa/X.Org developers for in effect a "new OpenGL Linux ABI" for allowing multiple Linux OpenGL drivers to happily co-exist on the same system. This makes things much easier than having different drivers overwriting the libGL files, complications with driver installation/uninstall, etc. It was long overdue but finally was seeing upstream support in 2016.

  • Wayland 1.13 Planned For Release Next Month

    Wayland 1.13 has been in development since September while the plans today were firmed up for releasing it in February.

  • Tegra/Nouveau Render-Only Gallium3D Support
  • Building Mesa from source, a guide

    If you are using Mesa (FOSS OpenGL/Vulkan drivers on Linux), you can be in situation when it introduces some new features upstream, but it didn't make it into your distribution yet and it can take quite a long time for that to happen. Certain games can become playable with that change, or it can be a performance optimization that speeds up already working games, or may be you simply want to test the newest Mesa itself - either way, you might be interested in running the latest development version of Mesa for various reasons. At the same time you don't want to mess up your system with an unstable graphics stack.

At the end of December I posted a number of Linux workstation/server distribution benchmarks while this article has the results from the more desktop-focused (non-graphics) Linux distribution benchmarks. Up for benchmarking off a Skylake NUC in this article was Antergos, Fedora 25, Ubuntu 16.10, openSUSE Tumbleweed, Debian 9 Testing, and Intel's Clear Linux.

  • AMD Has Been Working On An Open-Source GPU Debug Tool, To Be Released Soon

    Yesterday we noted the new open-source AMD GPU debugging tool being developed by a Valve engineer as part of their work on the open-source RADV/RadeonSI/AMDGPU code. It turns out AMD has officially been working on a GPU debugging tool too.

    As noted in that article yesterday it was sad that AMD hadn't to date worked on a full-featured debug tool, especially considering how good Intel's intel-gpu-tools is for debugging and testing, and how many years already AMD has been working on their open-source driver stack without having some official and public open GPU debug tool. Fortunately, it turns out that AMD has been working on such a utility.

  • OpenGL 4.3 Lands For Maxwell With Nouveau Gallium3D, Plus 1.5~3.5x Performance Boost

    It should be a busy end of week for Mesa with the Mesa 17.0 feature freeze being this weekend. In addition to Haswell hitting OpenGL 4.2, Nouveau's NVC0 Gallium3D driver has enabled OpenGL 4.3 support for newer Maxwell and Pascal hardware.

  • OpenGL 4.3 now available in Mesa for nouveau (NVIDIA) for Maxwell and above

    Samuel Pitoiset (Valve developer) just put some fresh work into Mesa-git that enables OpenGL 4.3 with nouveau (NVIDIA) for Maxwell and above.

  • Haswell should now see OpenGL 4.2 thanks to recent work in Mesa

    Mesa is continuing to progress rapidly, as of today Haswell should now support OpenGL 4.2 ready for the next release of Mesa. Only a few days ago Haswell gained OpenGL4, so this progress is amazing.

    Mesa 17 should arrive soon, which means this will be in the next stable release. Mesa switched their versioning, so Mesa 13.1 is now Mesa 17 as they are using a year-based version model.

  • OpenGL 4.2 Now Exposed For Intel Haswell On Mesa 17.0

    Days ago we mentioned the patches were lining up to get Intel's Haswell to OpenGL 4.2 and this morning those patches have landed in Mesa Git ahead of the branching for the Mesa 17.0 release.

  • Updated AMD DC/DAL Patches For Polaris 12, 5K VSR

    Harry Wentland of AMD on Wednesday posted updated DC (DAL) display patches for the AMDGPU code-base.

    This is just the latest of long-running work on getting the DC display stack into shape for hopefully merging into the mainline Linux kernel later this year.
