I am getting old. Back in my day, if you wanted top notch CPU performance, you had to go with a high-end x86 chip, or, if you had deeper pockets, you could get something exotic, like a PowerPC system. The industry’s dependence on x86 processors appeared to be increasing, not declining.
Ten years ago, Apple joined the x86 club, and this prompted many observers to conclude the era of non-x86 processors in the mass market was over. Just a few years later, they had to eat their words, and yet again, Apple had something to do with it. ARM servers are coming, and they could revitilise the server industry.
