In fairness, they are in a much better situation. They could swap to AMD with no real arch changes but I imagine they also would prefer their own CPUs. The fact of the matter is that these CPUs are built on the same exact process as the A12 by the same fab. I would expect, at the scale they are working, a next Apple ARM cpu could be scaled to Rome core counts and have “close” performance at hilariously lower prices.
- cududa 7y agoThat’s not really true. Most of MacOS is optimized for intel processors. Things like branch prediction and media encoding/ deciding are extremely different at a low level on AMD/ Intel, and Apple would need to make an enormous investment to rewrite all their perf specific components for AMD.
