    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

        Sustained performance is usually based on cooling, not the chip. There is no reason the iPhone chip can't sustain its performance if you give it a small fan.

        So whatever your argument is, it doesn't make much sense.

        The M6 is based on A20 Pro and it sustains its performance in a Mac Mini indefinitely - likely longer than Ryzens.

          Yeah but we are talking about the IPhone not the mac mini!

          I can believe the core with active cooling can sustain good performance at least, but not in the IPhone.
