That's true on CPUs, but I think the parent was talking about GPUs. AFAIK (I have not been able to get very much detailed information on GPU performance characteristics), GPUs tend to do better at such things, in part due to the great width and lower clocks (eg trig functions in just a few clock cycles). AVX512 may not have killed the GPU market, but consider SIMD on CPUs for flavour: float FMA and add have identical throughput on intel.
