It's not a counter-point you think it is. ARM is not a primary reason why Apple's M series are so much better. If it is, other ARM should be able to match, but they don't. Simply put, Apple built a good microarchitecture and a pipeline - e.g. M1 has, e.g. 600 reorder buffer. Back then, this was 2x of most other CPUs, regardless of ISA. This is not something you can just throw more transistors at it - you need all the other parts of the processor optimized in order to make that useful, and Apple did. Simply, M-series are one of the best out-of-order pipelines ever built.
