Initial Benchmarks Of The AMD AOCC 5.0 Compiler On 5th Gen EPYC

Last week when launching the AMD EPYC 9005 "Turin" processors, on the same day AOCC 5.0 was quietly released as the newest version of AMD's Zen-focused compiler derived from LLVM/Clang. With not only adding AMD Zen 5 "znver5" support but also additional vectorization improvements and other performance optimizations, I was eager to run some benchmarks of AOCC 5.0 against the open-source GCC and LLVM/Clang compilers. Here are those initial benchmarks using dual AMD EPYC 9755 128-core Zen 5 processors.
