How did AMD Ryzen get 50% faster in two years?

    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

        I don't think you are correct for single-core performance.

        A20 Pro scores around 4725 at 8.9w. Geekerwan's review showed that the iPhone 18 pro could dissipate as much as 6.4w during long gaming tests. Cutting power by 50% likely still keeps around 80% of the clockspeed.

        As 9950x scores around 3400-3450 in geekbench, or around 28% slower.

        There's a very good chance that the iPhone single thread performance is genuinely faster even during sustained loads.
