I am secretly hoping that at least for Desktop Mac, Apple could switch to AMD. They could leave the Mac Pro and iMac Pro for Xeon ( Or they could choose AMD and that will be EPYC ) But right now it is very hard to argue for purchasing Intel when AMD offer many more cores for lower price at the expense of ~20% peak single threaded performance.

Unless Intel offer Apple very good deal but I thought part of the Intel / AMD agreement was Intel can not use any tactics to undercut AMD with incentives or rebate or something similar.

At the same time Intel is like assembling old Apple alumni from CPU to GPU.
