This decision was made probably at least 3 years ago before the full extent of Intel's problems were clear. So why make this move? It's a long list. - Greater confidence in TSMC vs Intel to deliver process improvements - Leverage in house silicon design expertise - Leverage Apple's collaboration with TSMC - More modern CPU architecture - Single architecture across all products (so can run iPhone apps on Mac) - Ability to incorporate Apple's own IP (e.g. neural engine) in SoC - Cost savings - Full control of the hardware design I've not mentioned performance as this follows from the other factors. Only one of these benefits would be delivered by moving to AMD. So some short term transition pain but I think this would be pretty compelling from Apple's perspective when the decision was made.
