GCC 13 vs. Clang 17 Compiler Benchmarks, Early Clang 18 & GCC 14 Development Benchmarks

The Clang-built binaries for the Kvazaar H.265 encoder tended to be slightly faster than GCC.

The different binaries were quite close with the SVT-AV1 open-source AV1 video encoder benchmarking.

Overall for the video encode benchmarks the results tend to be quite close due to most encoders relying on a lot of hand-tuned code.
