Feature request: Add AVX512 support and re-test AVX2 benchmarks on AMD platforms #79

Closed tuzz closed 1 year ago

tuzz commented 1 year ago

It would be great if the crate detected AVX512 support and used it if the CPU supports it.

Do you know if the AVX2 slow down for AMD platforms is still an issue on modern CPUs?

Thanks

Hi Chris,

thanks for your interest in.

I checked results one month ago approx. on :

Results unfortunately still confirms that performance is better when using SSE2 path rather than AVX2. However, the performance gap is just in all the yuv to rgb conversions (so just a subset of all the available conversions).

A deeper analysis reveal such conversions are still unoptimal so first task will be switch to an improved versions of such conversions which in turn may lead to remove the intentional fallback.

Regarding the use of AVX512 it should be first detected whether the conversions are memory or cpu bound, as if they result to be memory-bound AVX-512 adoption will be almost useless (unless there is some magic instruction in the set devoted to color conversion).

Here's the relevant data (conversions that results in a pessimization):
