I thought that M1 Pro/Max single-core performance was roughly the same as M1, and it’s only the additional performance cores above the 4 in the M1 that allow HQP to do heavier lifting on the filter side of processing (assuming the 1st 4 performance cores are used for modulation). But maybe there are additional improvements in cross-core communication, etc. Still haven’t seen real-world results with M1 Max and HQP - have you?
If the Mac Pro M1 variations are just about additional cores I am unclear if it will be of benefit to HQP.
