Give some examples where all the software and everything is switching to ARM based CPU and doing well? As a example looking at
Huawei’s ARM-based desktop PC could leave you scratching your head.

First the ARM while speedy in a iPhone or iPad Pro when running MacOS 11 might not be that efficient as a desktop when you push it.
Interesting, so you’re saying Huawei has written their own desktop OS and designed and built their own custom ARM-based chips to run it on, and they didn’t get very good performance? I wasn’t aware of that. Do you have an more info on this?
Every time I see someone say, “oh, sure, ARM is fast enough for a phone, but not for a desktop”, I’m always a bit astonished. Apple has built the absolute fastest, highest performance phone chips on the planet, designed specifically to run in the extremely limited mobile environment - hiding behind the screen in a 1/4” thick machine with no airflow, no active cooling, and quite limited battery capacity. And they’ve invested huge amounts of time and money in developing a world class processor design team. Do you really think they’ll just take whatever their current phone chip is and drop it in a laptop or desktop system?
I fully expect that, several years ago, they told the chip design team, “these new A-series chips are fantastic - now, we’ve got a side project for you - we want you to design us two new chips: one for a system with more room, active cooling, and 5x the battery capacity available, and the other for a system with
much more cooling capacity and
unlimited 3.3V/5V DC available and no batteries (both with tons more RAM). Now, just how much CPU can you build for us in those two scenarios?” And I expect we’ll see the first answers to those challenges in the fall.
You’re making the mistake of comparing specific chips optimized to run in phones with chips optimized to run in desktop systems, and assuming that’s a fair comparison and representative of what Apple will ship. You haven’t yet seen what an ARM chip
designed for laptop/desktop use is capable of. The Intel/AMD x86_64 instruction set doesn’t have any inherent advantages over the ARM instruction set. But ARM chips tend to have
much higher performance per watt (this is why you don’t see phones running x86 chips, no matter how much Intel would like that). The latest iPhone/iPad chips beat a lot of laptop systems on performance already, and the chips they’ve
designed for laptop/desktop use are going to be even faster.
