GCC 13 vs. Clang 17 Compiler Benchmarks, Early Clang 18 & GCC 14 Development Benchmarks
GCC still had an advantage over Clang in Coremark on this Ryzen Threadripper 7995WX system.

Clang maintained an ever so slight lead in the avifenc AVIF image encode benchmarks.
The tables flipped with C-Ray where GCC continues to yield faster performance.
