Arm Processors with Mac Pro Level Performance Possible Today

[chucker23n1]

Anything coming out of Apple or the Mac App Store goes through their Bitcode process, so it's compiled/customized for the right/current CPU, and they got fat binaries (containing code for multiple architectures) worked out pretty well last time.

Bitcode still isn't mandatory on the Mac App Store, though.

So it's much less of a hard either/or transition. They could come out with one new Mac using an ARM chip, like a revived MacBook, that would hugely benefit from the increased power savings, and then slowly work their way up the line over numerous years. By the time they got to the Mac Pro, Intel compatibility might be less vital. In that case, the current Mac Pro wouldn't be a stop-gap per se, it'd live a full life, and would be followed by an ARM replacement, likely using the same chassis and much of the same technology.

Yup.
