With the recent stable releases of LLVM's Clang 16 and GCC 13 compilers there is now initial AMD Zen 4 "znver4" support in these open-source compilers. Curious about the performance difference between these two compilers on the very newest AMD 4th Gen EPYC "Genoa" server processors, I ran some LLVM Clang 16.0 and GCC 13.1 benchmarks on the flagship EPYC 9654 2P Linux server.
