AMD AOCC 2.3 Squeezing Out Extra Performance For EPYC Over GCC 10, Clang 11

In total 89 different C/C++ benchmarks were tested across these three compilers on the AMD EPYC 7502 system running Ubuntu 20.10.

The AOCC 2.3 compiler came in first place for 69% of the tests whether it be a miniscule or dominating lead...

AOCC 2.3 was in last place for just 11% of the tests.

If taking the geometric mean of all 89 benchmarks, AOCC 2.3 was about 7% faster than GCC 10.2 or 5% faster than LLVM Clang 11 for which AOCC 2.3 is based.
