GCC vs. LLVM Clang Compiler Performance On AMD's Ryzen
Clang continues to lead in delivering shorter compilation times.
But GCC is back on top with the C-Ray multi-threaded ray-tracer performance.
While the Stockfish chess performance is too close to call between Clang 3.9 and GCC 6.3, but this is yet another case where the newer compiler releases are slower than the current stable branches.
GCC 6.3 was leading in many of the Bullet Physics benchmarks.
