AMD Rembrandt: Windows 11 vs. Ubuntu Linux Performance

First up are a few graphics tests of comparable quality under both Windows and Linux, since after all the new RDNA2 Radeon 680M graphics is one of the most exciting aspects of Rembrandt in moving past Vega/GFX9.

With the demanding Unigine Heaven benchmark the Windows 11 Pro OpenGL performance was trailing Linux by a few frames... But as noted elsewhere, AMD is in preparing to introduce a revamped OpenGL driver for Windows so later this year it will be interesting to see if that gap is closed.

When running Unigine Heaven with its Direct3D 11 renderer, it was running at similar speed to the Linux OpenGL performance for this demanding test case.

Similarly, in open-source gaming tests using OpenGL the Linux RadeonSI Gallium3D driver was much faster than the current Radeon Software for Windows OpenGL driver.

With the yquake2 open-source, cross-platform game on both OpenGL and Vulkan the open-source Linux driver was showing much better performance.

With the ParaView workstation visualization software for data analysis and other use-cases, the Ubuntu Linux performance with its stock Mesa driver packages was much faster than the current AMD Radeon Software driver on Windows 11 except for the wavelet volume test was a rare upset.
