ACES DGEMM benchmark with settings of Sustained Floating-Point Rate. CentOS Stream 9 was the fastest.

Occasionally there are some workloads where Clear Linux doesn't pay off, but when relaying the details to Intel software engineers they accept it as an ongoing challenge.

Intel Open Image Denoise benchmark with settings of Run: RT.hdr_alb_nrm.3840x2160, Device: CPU-Only. Clear Linux 41150 was the fastest.
Intel Open Image Denoise benchmark with settings of Run: RT.ldr_alb_nrm.3840x2160, Device: CPU-Only. Clear Linux 41150 was the fastest.
OpenVKL benchmark with settings of Benchmark: vklBenchmarkCPU ISPC. Clear Linux 41150 was the fastest.

Even in some cases like Open Image Denoise or the Open Volume Kernel Library of using the same official software binaries across distributions, Clear Linux could squeeze out greater performance than the rest.

7-Zip Compression benchmark with settings of Test: Compression Rating. Clear Linux 41150 was the fastest.
7-Zip Compression benchmark with settings of Test: Decompression Rating. Clear Linux 41150 was the fastest.

As shown in other Phoronix articles, many of the same Clear Linux performance optimizations can also help out with maximizing AMD x86_64 Linux performance too.
