Under Linux (or Windows?)
- On non-AVX load [1], max CPU ratio is the ratio I set.
- On AVX load, max CPU ratio is (the ratio - AVXOffset) [2]
Under macOS + Clover
- Max ratio is always (ratio - AVXOffset)
Does 'AVX offset' require OS support, or only BIOS support is sufficient?
If it is the latter case, does it mean Clover does a mistake at calculating the max ratio/freq?
-------------
[1] Prime 95 small FFT with 'CpuSupportsAVX=0'
[2] AVX makes more heat that normal instructions and is used for limited cases (e.g. video software encoding). IMHO it is a good idea to set a higher freq for normal cases, and use AVX Offset to reduce freq in AVX use cases.
