Here is an up-to-date look at how the very latest Mesa 20.1 Git performance is for the Radeon "RADV" Vulkan driver both out-of-the-box and when enabling the Valve-backed ACO compiler back-end alternative to AMDGPU LLVM. Plus there are benchmarks of the latest AMDVLK open-source AMD Vulkan driver and also when using AMDGPU-PRO's Vulkan packages that still rely upon AMD's proprietary shader compiler.
