Just speculating, but I'd imagine they will use the same M1 Pro/Max SoC setup the MacBook Pro has but perhaps with some added beefier options as they don't need to worry about the thermals so much in an all-in-one desktop. Obviously battery life doesn't need to be considered for a desktop...Do you guys think that the M1 Pro/Max will have a higher TDP when used in the iMac Pro than in the MBP?
I have a feeling the iMac Pro (or whatever they call it) will be firmly aimed at the "Pro" market so pricing will certainly be on the high-end.
