Radeon's Open-Source Linux GPU Driver Has Nearly Caught Up With Windows' Driver

Over the past few months we have seen some incredible progress made to the RadeonSI Gallium3D driver as well as AMDGPU (and the RADV Vulkan driver, though not the focus of today's article) as well as the Mesa 3D stack as a whole. The open-source Radeon Linux driver is much faster now than where it was last year and is becoming competitive with NVIDIA's Linux driver performance. For seeing how close the AMDGPU+RadeonSI stack is now to Windows, here are some fresh benchmarks.

NVIDIA vs. Radeon VDPAU Mesa 17.2 Video Decode Performance

In yesterday's GeForce GT 1030 Linux review, a $70 USD graphics card that's low-profile and passively-cooled, I featured a number of NVIDIA VDPAU video acceleration benchmarks. But a question came up about Radeon VDPAU performance, so here are some benchmarks on that front, but they are far from ideal.

RADV vs. AMDGPU-PRO Vulkan Performance vs. OpenGL In May 2017

With the open-source RADV Radeon Vulkan driver recently hitting the milestone of effectively being Vulkan 1.0 compliant, I figured this warranted a good time for running a fresh open-source Vulkan vs. AMDGPU-PRO Vulkan performance comparison on various graphics cards. For additional context, the RadeonSI and AMDGPU-PRO OpenGL numbers are also present to provide additional value.

Radeon RX 550: AMDGPU-PRO vs. DRM-Next + Mesa 17.2-dev

Earlier this week I posted a number of Radeon RX 550 Linux benchmarks making use of AMD's popular open-source driver stack. For those wondering how the open-source driver compares to the AMDGPU-PRO hybrid proprietary driver for this sub-$100 Polaris GPU, these benchmarks will interest you.

Nouveau Re-Clocked With DRM-Next Linux 4.12 + Mesa 17.2-dev vs. NVIDIA 381 Driver

A few days back I posted benchmarks of the initial GTX 1050/1060/1070/1080 Nouveau 3D support. As expected, the performance was rather abysmal with re-clocking not being available for Pascal (or Maxwell) GPUs on this open-source NVIDIA Linux kernel driver. For those trying to use Nouveau for Linux games or care about your GPU clock speeds, currently the GTX 600/700 "Kepler" series is still your best bet or the GTX 750 "Maxwell 1" is the last NVIDIA graphics processors not requiring signed firmware images and can properly -- but manually -- re-clock with the current Nouveau driver.

Radeon RX 580: AMDGPU-PRO vs. DRM-Next + Mesa 17.2-dev

Last week I posted initial Radeon RX 580 Linux benchmarks and even AMDGPU overclocking results. That initial testing of this "Polaris Evolved" hardware was done with the fully-open Radeon driver stack that most Linux enthusiasts/gamers use these days. The AMDGPU-PRO driver wasn't tested for those initial articles as it seems to have a diminishing user-base and largely focused for workstation users. But for those wondering how AMDGPU-PRO runs with the Radeon RX 580, here are some comparison results to DRM-Next code for Linux 4.12 and Mesa 17.2-dev.

AMDGPU-PRO 17.10 OpenCL vs. NVIDIA Shows Problems

Last week I began posting a number of AMD Radeon RX 580 Linux benchmarks but not covered so far has been the OpenCL compute performance considering the Clover-based compute stack isn't good enough for benchmarking and is basically unmaintained these days by AMD. Meanwhile, their ROCm stack is still being brought up and is not yet fully-opened nor optimized yet for performance. Thus for those with desktop cards looking for basic OpenCL support are left with the AMDGPU-PRO hybrid driver with its closed-source OpenCL driver. In this article are some fresh OpenCL benchmarks of AMDGPU-PRO on the RX 580 and other Radeon GPUs compared to NVIDIA with its Linux OpenCL driver.
