Radeon Linux 4.6 + Mesa 11.3 vs. NVIDIA Linux Performance & Perf-Per-Watt
Next up are some 4K results.
Counter-Strike: Global Offensive at 4K is much more competitive with the AMD Linux driver stack compared to when it was run at 1080p against NVIDIA. Here the open-source AMD performance is close to where it should be at relative to NVIDIA.
The performance-per-Watt also looks more appropriate with CS:GO at 4K rather than how it is when being bottlenecked by the driver in other tests.
But Unigine Valley at 4K is still showing the AMD Linux performance much lower than it should be, but alas the Radeon/AMDGPU DRM and RadeonSI Gallium3D in Mesa are constantly evolving.
