Radeon RX 6600/6700/6800 XT: RADV vs. PRO Vulkan Driver Performance

The Radeon Software for Linux "PRO" Vulkan driver does have the advantage of being the only viable option right now for Vulkan ray-tracing... Mesa's RADV is currently working towards supporting Vulkan RT extensions but at the moment its performance is very slow and not really usable for end-users. Though some developers have also criticized the PRO Vulkan driver's ray-tracing support as buggy, so for right now Linux gamers are best with NVIDIA graphics if serious about ray-tracing although there isn't much software yet on Linux that can make use of these extensions.

When taking the geometric mean of all the Vulkan benchmarks that were successfully tested on both drivers, the RX 6600 XT and RX 6700 XT were both around 4% faster on Mesa 21.3-dev's RADV than the Radeon Software for Linux 21.30 PRO packaged driver stack while the higher-end Radeon RX 6800 XT was 7% faster on RADV when tested on Ubuntu 20.04 LTS.
