For those wondering how AMD’s latest generation Radeon RX 6000 series now competes between the Linux driver options of AMD’s Radeon Software for Linux 21.30 “PRO” driver stack and the latest driver components Fully open source upstream of Mesa and the mainline Linux kernel, here’s a new comparison.
Radeon Software for Linux 21.30 remains the last public release of AMD’s packaged Linux driver, the benchmarking for this article being of their “PRO” driver stack option which includes their proprietary Vulkan and OpenGL driver components. On the upstream pure open source side, testing was done using Mesa 21.3-devel Git at time of testing, paired with Linux 5.15 Git kernel to show the current potential of OpenGL RadeonSI and Vulkan open source drivers. RADV.
The graphics cards used for this Linux driver comparison were the latest generations of Radeon RX 6600 XT and RX 6800 XT graphics cards (the most high-end AMD SKU I have available with still no access to the RX 6900 XT) as well as the previous generation of Radeon. RX 5700 XT for reference. No other changes were made to the system during testing other than swapping driver and GPU configurations when running an assortment of Linux gaming benchmarks.
