But there isn't a 5nm version of those... And laptop battery life is vastly different between these two.

  Can you link a good test result that proves this? The 7nm Ryzen 5000 mobile chips are not very power hungry either.

      This doesn't contain any comparison graphs relevant to my question, and couldn't, because it's from November. The Ryzen 5000 mobile chips came out this year.

        Here’s the AMD benchmark and it’s using up to 3x the power of the M1. https://www.anandtech.com/show/16446/amd-ryzen-9-5980hs-cezanne-review-ryzen-5000-mobile-tested/4 https://www.anandtech.com/show/16446/amd-ryzen-9-5980hs-ceza...

          Isn't it 35W for the 5980hs vs. 26.8W for the M1, so up to 1.3x? https://www.anandtech.com/show/16252/mac-mini-apple-m1-tested https://www.anandtech.com/show/16252/mac-mini-apple-m1-teste...

          That’s not the right part, the 5800U is the low power Ryzen competitor.

            I don't see any reviews for laptops with that CPU. It's hard to compare against something no one can test.
            • CyberDildonics 6y ago
              Then why did you compare them?

    Is this relevant? https://www.youtube.com/watch?v=r5bAMoQt7EQ https://www.youtube.com/watch?v=r5bAMoQt7EQ

  The difference isn't that big: https://www.youtube.com/watch?v=WKN9nvXTGHE https://www.youtube.com/watch?v=WKN9nvXTGHE And for 5nm, I'm quite sure AMD already has contracts for that with TSMC. So the gap should be even smaller.
  • foldr 6y ago
    It has less battery life and less performance (judging by Cinebench, at least), so it is a fairly substantial difference. And it's quite possible that Apple will remain one TSMC process ahead of AMD for the next few years, even if AMD do put out 5nm chips in the near future.

      The surface laptop has a Ryzen 4000 CPU, not Ryzen 5000.
      • foldr 6y ago
        I assume the person I was responding to was talking about the laptop in the video that they linked to.
  • ianai 6y ago
    His “as tested” was 11 hours for AMD and 13 for M1. His “max time use” for AMD was 14.5 and 20 for M1. That’s a 38% greater time for the M1 in a best possible outcome and 18% on “average”. Substantial differences that users would perceive noticeably.

      I’m not so sure. I think it reaches a meaningful maximum. Can I do an entire days work on the laptop? Yes to both. Can it last an entire flight, even a long one? Yes to both. It’s not that it doesn’t matter at all, it’s just that it matters a lot less once you’ve checked boxes like that. The effective experience of both would be “you only need to charge it overnight”
