The Performance Impact To AMD Zen 2 Compiler Tuning On GCC 9 + Znver2

One of the areas that I always have "fun" benchmarking for new CPU launches is looking at the compiler performance. Following the recent Ryzen 3000 series launch I carried out some initial benchmarks looking at the current Zen 2 performance using the newest GCC 9 stable series with its "znver2" optimizations. Here is a look at how the Znver2 optimizations work out when running some benchmarks on the optimized binaries with a Ryzen 9 3900X running Ubuntu 18.04 LTS.
