From you link - Intel is topping the performance charts (alongside AMD in SC) - they probably tune power usage agressively to achieve these results. I would guess it's more to do with coming from desktop CPU design to mobile vs. phones to laptops.

>From you link - Intel is topping the performance charts (alongside AMD in SC) - they probably tune power usage agressively to achieve these results. Cinebench 2024 ST: * M3: 142 points * X Elite: 123 points * AMD HX 370: 116 points * AMD 8845HS: 102 points * Intel 155H: 108 points Amongst each company's best laptop ST SoCs, no, Intel and AMD are far behind in both ST scores and perf/watt. If you're referring to desktop speeds, then yes, Intel's 14900k does top the charts in ST Cinebench but it likely uses well over 100w. I mostly care about laptop SoCs. In the case of the M3, it doesn’t even have a fan.

  That's what I'm thinking - they make trade-offs to reach peak performance in desktop designs that don't translate optimally to laptops and when you start from mobile designs you probably made the opposite trade-offs - that would be my guess for the discrepancy.

    I'm pretty sure that M3 Max closely matches the 14900k in ST speeds but using something like 5 - 10% of the power.

      Not sure - they had power/thermal envelope in desktop parts and no difference in performance AFAIK.

    Laptops vastly outsell desktops, so this tradeoff means hurting the majority of your customers to please a small minority. Servers also care about perf/watt a LOT and they are the highest profit margin segment. Why would AMD choose a target that hurts the majority of their market unless there wasn't another good option available?

      The architecture started in desktop space and data center/mobile was an afterthought up until Intel shitting the bed repeatedly. If they redesigned from ground up they could probably get better instructions/watt but that would look terrible if it wasn't accompanied by a perf boost over previous generation. Just like Apple doesn't seem to scale well with more power.

        > Just like Apple doesn't seem to scale well with more power. How do you know this? When has Apple ever given 400w to the M3 Max like the 14900KS can get up to? PS. An M4 running at 7w is faster in ST than a 14900KS running in 250w+.
