Open-Source AMD Radeon Linux Graphics In Great Shape For Workstations, Handily Beating Proprietary Driver

Right off that bat for SPECViewPerf 2020 v3.0 on Linux at 1080p, AMDGPU-PRO simply was in bad shape for SPECViewPerf 2020... Even the stock Ubuntu 20.04.4 HWE stack was running better than AMDGPU-PRO OpenGL while switching over to Mesa 22.1-dev provided a noticeable speed-up for the SNX-04 viewset.

The legacy proprietary OpenGL driver performed very poorly against RadeonSI for the CREO-03 viewset too... With the minimal difference for the PRO driver across the tested resolutions, it seems some big bottleneck is at play for that binary blob.

SPECViewPerf 2020 with the MAYA viewset was one of the rare cases where AMDGPU-PRO delivered better performance than the Ubuntu 20.04.4 stock driver, but that is no longer the case for RadeonSI with Mesa 22.1-dev.. With the newer RadeonSI/Mesa optimizations, Mesa 22.1-dev is much faster than the current OpenGL driver found in Radeon Software for Linux 21.50.
