Single core performance still worse than an iPhone.
The x86 folks lost the ball completely. For workstation/ mobile needs you go to arm. For matmul at scale you go to gpus.
I guess windows gaming with separate gpu is the only remaining market for them.
Unless Nvidia releases a motherboard with an arm cpu on top of their RTX cards, and then that market is gone too.
The IPhone runs on a battery, with no active cooling.
There is no chance the sustained single core perf is better than a 150=200+w ryzen with a big noctua cooler on it. The power draw alone would kill the battery in a few minutes(?), and the heat would make it catch fire. lol
