Radeon Linux OpenGL Driver Continues Giving Its Best Against Windows 10

Tomb Raider at 1080p with ultra settings saw the Linux performance with the latest Radeon drivers at around 72% the speed of Windows 10 with Radeon Software. The minimum frame-rates on Windows remained close to the average frame-rates on Linux.

While running Tomb Raider at 4K with high quality settings, Linux was at under 70% the performance of Windows and the minimum frame-rates on Windows was now around the peak frame-rates on Linux.

Total War: WARHAMMER at 1080p saw the RX 580 deliver around the same performance on Windows and Linux. But with the RX Vega 64 on Ubuntu Linux it came in at about 81%.

When running WARHAMMER at 4K, both graphics cards on Linux were below the Windows performance.

That's where things stand today with the open-source AMDGPU+RadeonSI driver stack compared to the latest Radeon Software on Windows 10. As shown with the initial tests, the RadeonSI OpenGL performance can beat the OpenGL Windows performance with the Radeon Software driver when the software under test is of similar quality, but when comparing Direct3D games to their Linux OpenGL counterparts it's only around 60~80% the performance but with some exceptions. I'll be working on some new Vulkan cross-OS comparison tests soon. If you appreciate all of our Linux hardware benchmarking work at Phoronix, consider showing your support by joining Phoronix Premium.
