👁 C-Ray benchmark with settings of Resolution: 4K, Rays Per Pixel: 16. Clang 22 was the fastest.

👁 C-Ray benchmark with settings of Resolution: 5K, Rays Per Pixel: 16. Clang 22 was the fastest.

Clang 22 was producing much better performance for the C-Ray CPU-based ray-tracer than the GCC 16 built binaries.

👁 FLAC Audio Encoding benchmark with settings of WAV To FLAC. Clang 22 was the fastest.

👁 LAME MP3 Encoding benchmark with settings of WAV To MP3. GCC 16 was the fastest.

Clang 22 also yielded the fastest FLAC encoder while GCC 16 built the fastest LAME MP3 encoder.

👁 Liquid-DSP benchmark with settings of Threads: 32, Buffer Length: 256, Filter Length: 32. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 32, Buffer Length: 256, Filter Length: 57. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 64, Buffer Length: 256, Filter Length: 32. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 64, Buffer Length: 256, Filter Length: 57. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 128, Buffer Length: 256, Filter Length: 32. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 128, Buffer Length: 256, Filter Length: 57. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 32, Buffer Length: 256, Filter Length: 512. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 64, Buffer Length: 256, Filter Length: 512. Clang 22 was the fastest.

👁 Liquid-DSP benchmark with settings of Threads: 128, Buffer Length: 256, Filter Length: 512. Clang 22 was the fastest.

For the Liquid-DSP digital signal processing library there was some very strong wins for LLVM Clang 22 while GCC 16 was regressing compared to GCC 15.
