There is good reason to believe that’s not the case. Oh having access to TSMC 5nm to other designs would definitely help reduce the gap, but we can see from like-for-like node implementations of previous A series chips and other ARM designs that Apple has a significant lead in architecture too. M1 has some really impressive new architectural features of its own that it’s hard to imagine their competitors being able to replicate any time soon.

According to AMD you get >1.25 performance at 1/2 the power usage when chips go from 7nm to 5nm. Some of that might be architecture but when x86 gets to 5nm the difference in performance might be fairly negligible.

The competition isn’t other ARM players, it’s Intel and AMD. Both are on larger nodes for now.
