Sure, the idea is it makes little sense to say and instructions set is itself and more efficient or faster. It is only the implementation that matters. It's equivalent to saying macos is faster than windows cause of how it looks. It's the implementation that matters.

On top of that, the specific argument they make "smaller, more optimized instructions" is doubly nonsense because all modern high-end cpus, whether x86 or arm, break instructions down into smaller subparts and run those.

When apple's M1 came out, a lot of tech media outlets struggled to come up with a explainable reason for why it was so good beyond "appel gud engineering" and one of the main things a lot of them coalesced around was ARM somehow just being a better, faster isa, meaning a lot of people who know little about chips go around saying it and it's pretty irritating. I'm no chip expert either, but I do know Qualcomm/apple aren't making more efficient chips because of the ARM isa.
