AMD AOCC 3.2 vs. GCC vs. Clang Compiler Performance On Zen 3

Earlier this month AMD released AOCC 3.2 as the newest version of their LLVM/Clang-based compiler focused on delivering optimized Zen performance. With our initial AMD AOCC 3.2 benchmarks on Zen 3, there is nice incremental improvement compared to the prior 3.x releases. But how does this AMD-optimized compiler stack up against the upstream LLVM Clang and GCC compilers? Here is a look at the AMD AOCC performance against the current Clang and GCC C/C++ compilers.
