There is no proof that these outperform traditional CPUs at all. That is the reason you don't see them being used anywhere other than niche use cases or for cost reasons.
By 2017 there were three times as many smartphones than PCs, all running ARM chips.
The top four supercomputers all use RISC, and the fastest uses ARM.
As for supercomputers, >90% of them are Intel/AMD.
Will there be Razor laptops that last less than an hour on battery that can beat them? Sure.
Will there be people who complain that the Mac isn't fast enough when plugged in? Already happening: the recent Macbook Pros have had complaints about thermal throttling, that obviously slightly larger Dell with a decent fan doesn't have.
But Apple will build performance laptops, using ARM chips, and they will be faster than the equivalent Intel Macbooks if only because they aren't throttled.
The person you replied to said:
> There is no proof that these outperform traditional CPUs at all.
To which you replied talking about embedded market share and supercomputer which have nothing to do with that.
Since now you mention Apple and MacBooks, which haven't been even mentioned, I think you are answering to the wrong thread/post.
