NVIDIA Linux OpenCL Performance vs. Radeon ROCm / AMDGPU-PRO

Filed under
Graphics/Benchmarks

Earlier this week I posted some benchmarks of GPUOpen's new Radeon Open Compute ROCm OpenCL stack that premiered last month and they are working to make completely open-source. In those initial benchmarks I compared the ROCm 1.4 OpenCL performance to the existing AMDGPU-PRO OpenCL implementation on Linux. For those wondering how these two Radeon OpenCL stacks compare to NVIDIA, here are some fresh benchmarks.

Fedora vs. Ubuntu vs. openSUSE vs. Clear Linux For Intel Steam Gaming Performance

Filed under
Graphics/Benchmarks

With this week Clear Linux now being able to run Steam, I was excited to see how this performance-minded Linux distribution out of Intel's Open-Source Technology Center would compare to other more popular Linux distributions when it comes to Intel Linux gaming performance. Here are some benchmarks of this traditionally workstation/server-oriented Intel Linux distribution running some Steam Linux games.

For those that haven't read our past articles with Clear Linux benchmarks, it tends to perform very well for a variety of reasons. Delivering the best Linux performance possible on Intel hardware is one of their driving forces and include features like aggressive CFLAGS/CXXFLAGS by default, using CPUFreq over P-State for CPU frequency scaling, building software packages with function multi-versioning to support both older and newer processors, selectively choosing Clang vs. GCC compilers for each package based upon the performance, carrying some out-of-tree patches, and various other optimizations/tweaks as outlined at ClearLinux.org.

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

Filed under
Graphics/Benchmarks
  • 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.
