> What I expect we'll see are ARM chips that are power and performance competitive with x86 chips only for specific curated use cases.
Sorry but there is no justification for this. With the same thermal constraints there is every expectation that an Apple / Arm CPU would be more performant and efficient than a comparable x86. Why? Because aarch64 doesn't have the historical legacy that x86 has and Apple has already shown what they can do in the iPad etc. Sure they won't be triple digits but it will enough to be noticeable.
And, as you say, they will have the advantage of Apple's custom silicon for specific use cases. So best of both worlds.
