Radeon RADV "ACO" Performance On Mesa 19.3 Looking Good

Phoronix - Sun, 10/06/2019 - 08:17
With the ACO shader compiler back-end merged for Mesa 19.3 as of mid-September and more improvements merged since then, it's now very easy to try out this alternative to AMD's longstanding AMDGPU LLVM compiler back-end. ACO, which is developed by Valve and their contractors outside of AMD, is looking quite good not only for quicker shader compilation (more punctual game load times) but also helping the performance of some Vulkan-powered games. Here are our latest ACO benchmarks.

DAV1D vs. LIBGAV1 Performance - Benchmarking Google's New AV1 Video Decoder
