LLVM Clang 16 vs. GCC 13 Compiler Performance On Intel Raptor Lake
The JPEG-XL library applied slightly different build flags based on the underlying compiler detected but overall LLVM Clang was coming out noticeably faster than GCC on this Intel Raptor Lake system.
The TSCP chess program also saw more favorable performance when built with Clang.
The OpenMP Graphics-Magick performance was mixed based on the particular imaging operation whether GCC or Clang was faster on this Core i9 13900K Fedora Workstation setup.
The SVT video encoder performance results tended to be quite close between tested compilers, after all many video encoders rely on hand-tuned Assembly code.
The uvg266 open-source video encoder for H.266 was seeing better performance on Clang 16.
Clang 16 celebrated another win with VVenC, another H.266/VVC encoder.
