ISA doesn't imply performance characteristics.

It's like saying that programming language (syntax) has performance implication.

No, it doesn't. Everything is up to the compiler, runtime and standard library.

Of course there may be some feature that make compiler's life easier, but still things are way, way more complicated than "just take ARM ISA and you'll be king".

Also even if you assume that ARM has 1-2% better perf than x86, then how many people will risk transition over that? Some will, but majority will no.
