Last week Mesa 26.0-devel enabled the ACO back-end by default within the RadeonSI Gallium3D driver for all supported Radeon graphics cards by this open-source Linux driver. This move was done in the name of better performance, faster shader compilation times, and ACO being all-around better than the AMDGPU LLVM back-end these days for both OpenGL and Vulkan use. It was also noted that RadeonSI has "slightly better" viewperf performance with NIR+ACO than using the AMDGPU LLVM back-end. Curious about that SPECViewPerf impact, here are some benchmarks with the recently released AMD Radeon AI PRO R9700 graphics card...
