Description
Hello,
I tried benchmark on 7950x cpu and performance is in some tests up to 2.3x faster but in other tests much slower (like 0.3x) compared to classical sorting. Is amd implementation of avx512 not so powerful (and your code is not suitable for zen4) or is it something else ?
Thanks,
Jan

Research direction
Start by reproducing the reported benchmarks on an AMD 7950X, comparing the SIMD sorting results with classical sorting across the affected tests. Read the benchmark setup and AVX512 implementation paths to identify why performance varies; done means documenting the cause and a clear next step for the implementation or benchmark.
