More cores is an obvious next step, but I'm curious to see how well Apple can scale the unified memory architecture. Can you put 32 cores (plus cache) and enough memory to keep them busy on a chip that retains the advantages of the M1?
Edit: answers to a similar question on the other thread suggest that it's NBD to move the memory off package.
