LLVM Clang 16 vs. GCC 13 Compiler Performance On AMD 4th Gen EPYC "Genoa"

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.
