GCC 10 vs. Clang 10 Compiler Performance On AMD Zen 2 + Intel Cascade Lake

We delivered many benchmarks of Clang 10.0 on various CPUs following that updated LLVM compiler stack release earlier this year. With GCC 10 released earlier this month, we have begun our benchmarking of this annual feature release to the GNU Compiler Collection. First up is a look at the GCC 9 vs. GCC 10 vs. LLVM Clang 10 compiler performance on AMD Zen 2 and Intel Cascade Lake systems.
