GCC 8 & LLVM Clang 6.0 Compiler Performance On AMD EPYC - November 2017

With the TSCP chess benchmark, Clang maintains a small lead that has widened by a bit with Clang 6 that is currently in development.

Clang still trails GCC in some OpenMP multi-threaded benchmarks.

In many of our common scientific benchmarks, the current GCC and Clang C/C++ code compilers yield binaries that perform neck-and-neck.
