GCC 14 vs. LLVM Clang 18 Compiler Performance On Fedora 40
👁 John The Ripper benchmark with settings of Test: HMAC-SHA512. GCC 14.0.1 20240411 was the fastest.
Recently Clang has been picking up more performance wins at least on Linux x86_64.
👁 GraphicsMagick benchmark with settings of Operation: Sharpen. GCC 14.0.1 20240411 was the fastest.
Some workloads like GraphicsMagick have long yielded the best performance on the GNU Compiler Collection.
For workloads like video encoders that often rely on hand-tuned Assembly, there still can be some smaller performance differences between compiler builds.
