GCC 9 vs. Clang 8 C/C++ Compiler Performance On AMD Threadripper, Intel Core i9

The Threadripper 2990WX system saw a nice improvement with the SVT-HEVC H.265 video encoder when built under GCC 9.

The SVT-VP9 encoder meanwhile saw Clang producing the fastest encoder on the AMD system while the Core i9 7980XE was the fastest with GCC.

With Google's VP9 vpxenc encoder test, Clang again yielded the fastest binary on the Threadripper system.

Clang also had a slight lead with x264.
