For some HPC apps like QuickSilver there were some nice gains observed when built under Clang 21 rather than Clang 20 on this AMD EPYC Zen 5 server.
👁 WebP Image Encode benchmark with settings of Encode Settings: Default. Clang 21.1 was the fastest.
When looking at the WebP image encoding performance, Clang 21 was having a slight advantage over the Clang 20 built binaries but a much more pronounced lead when it came to encoding at the highest quality (100) with highest compression where there was a 30% improvement observed out of the new compiler.
