Mobile, desktop, laptop, edge, server. These are the domains of compute. 4 out of the 5 domains value power efficiency. Laptop that were once x86 are now coming round to Arm because it really does make a better product i.e battery life and thermals. For the server, savings in energy and cost of chip manufacturing, datacentres and users both benefit.

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"

It's more the fact that power efficiency is something Arm values quite lot in their philosophy since their products are used in mobile and edge devices.

So you're talking about Arm as CPU design, not as the ISA, yup?

Until the Windows developer community actually cares about ARM, they will continue to be nice to have laptops that most consumers won't care.

Microsoft isn't Apple or Google in this regard, dragging developers into new worlds, and it is quite telling that they had now to put up some kind of ARM advocacy action.
