One of the areas I've been meaning to run more benchmarks on this season has been for the recently released Clang 21 compiler. Back in September when LLVM Clang 21 was debuting I ran some initial benchmarks and found it to deliver some nice performance gains on AMD EPYC Zen 5 but then have been busy with other benchmarks/articles for expanding that testing. Recently with having some spare cycles and gratis access still to the Microsoft Azure HBv5 instance for AMD EPYC Zen 4 with HBM3, I ran some Clang 20 vs. Clang 21 performance benchmarks there for those wondering about any performance benefits of this new compiler release on Zen 4.
