Windows 10 Radeon Software vs. AMDGPU On Ubuntu Linux

Lastly are the synthetic OpenGL test results of GpuTest. However, here, the tests failed to run under Windows so this is just a look at the two AMD drivers on Linux.

Overall, the AMDGPU PRO driver stack was certainly competitive with the Radeon Software driver on Windows 10. The pure open-source driver stack with AMDGPU and RadeonSI Gallium3D was competitive with these closed-source driver components in many of the OpenGL tests with the big exception being Unigine Heaven and Xonotic at the more intense visual settings. In the less demanding tests, the Radeon R9 285 and R9 Fury on the pure open-source Linux driver was very competitive with the PRO driver on Linux and Radeon Software on Windows. The advantage of the PRO driver stack though is OpenGL 4.5 (compared to OpenGL 4.1~4.3 on RadeonSI, depending upon your Mesa version) and OpenCL 2.0 support with PRO compared to barely working CL with Gallium3D Clover.
