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

GCC remains much faster than Clang for the C-Ray ray-tracing performance.

With other open-source renderers, the GCC vs. Clang performance tends to be quite comparable with C-Ray being one of the longtime exceptions.

GCC also still produces a faster LAME binary for MP3 encoding compared to Clang.
