The performance of Clang continues to be quite fascinating and has certainly matured a lot on x86_64 and ARM64 in recent years.

Coremark on the EPYC 7763 was delivering noticeably better performance with GCC.

GCC also still was showing the best results for the C-Ray ray-tracer.

GCC also was leading with the Ngspice circuit simulator software.

GCC started off faster for the Liquid-DSP digital signal processing library but at the higher thread counts the Clang-built binary came out ahead.
