You think because they are making millions off x86 consoles today, it will be like that in the future?
The trend is clear. x86 will get eclipsed but nobody is claiming it has already happened.
When diesel trains arrived, the makers of steam locomotives had their strongest sales and profits. And no doubt both Intel and AMD have many years ahead with strong profits, especially in data centers, gaming rigs and consoles.
But that doesn't change the inevitable.
The 90s was a completely different ball game. RISC of the 90s was low volume CPUs. That made them cheap. Intel beat them on volume and ability to run on lower nm.
Now that game is completely turned on its head. ARM is the one with volume, and the best manufacturing in terms of node density is not Intel anymore. In fact Intel has been slipping for years.
AMD is not offering the fastest cores or the most performance per watt. Long term that is what matters in terms of whom will be able to build the most powerful CPUs.
