Stargate Digital Audio Workstation benchmark with settings of Sample Rate: 44100, Buffer Size: 1024. Clang 17.0.2 was the fastest.
Stargate Digital Audio Workstation benchmark with settings of Sample Rate: 192000, Buffer Size: 1024. Clang 17.0.2 was the fastest.

Meanwhile the Clang-built binaries had a measurable advantage for the Stargate digital audio workstation (DAW) open-source software.

libavif avifenc benchmark with settings of Encoder Speed: 2. Clang 18 23 Dec was the fastest.
libavif avifenc benchmark with settings of Encoder Speed: 6. Clang 17.0.2 was the fastest.
libavif avifenc benchmark with settings of Encoder Speed: 6, Lossless. Clang 17.0.2 was the fastest.

Clang maintained an ever so slight lead in the avifenc AVIF image encode benchmarks.

C-Ray benchmark with settings of Total Time, 4K, 16 Rays Per Pixel. GCC 14 23 Dec was the fastest.

The tables flipped with C-Ray where GCC continues to yield faster performance.
