But not the battery life.

totalZero 6y ago
Power efficiency is indeed one of the benefits of smaller process nodes, so it has a direct impact on battery life.

That's not entirely true. My Ryzen 4900hs laptop gets great battery life with integrated graphics. Not as good as the m1, but it's a zen 2 chip and we have yet to see what zen 3 mobile will do. Apple clearly has a huge advantage here with a cutting edge process and for all practical purposes unlimited money to throw at this. Their cash on hand is more than AMD s full market cap.

  Can you clarify what you mean by "great" i.e. in hours. From all benchmarks the Apple M1 laptops are around 1.8-2x more battery life than anything from AMD/Intel.

    My friend sent me a screen shot from `powercfg /batteryreport` on his Asus Zephyrus G14 (Ryzen 9 4900HS) and it had consumed 16,704 Wh of battery in 1:47:27 of active use. That tracks to about 8.5 hours (capacity showed just under 80 Wh).

      I've been averaging about ~15 hours per charge on my 13" MacBook Pro M1 so far. That includes compiling/running tests/and not just web browsing/checking mail.

        Its such a hard comparision though. You are running the newest of the newest. My Lenovo Thinkpad X390 which i'm sitting on right now for a while, still has ~8h left to go. Chrome with 30 tabs, intellij etc. open and running. I do assume the M1 is doing a great job, don't get me wrong, but i would like to see a more objective comparison. Personally speaking, the most interesting thing for me to see is that Apple now put a very strong SoC on all its models. From Air to Pro, with a relative good price point (as long as you don't upgrade anything...)

        Going by TSMCs claim of 30% better power consumption at iso-speed would put the battery of the G14 at 11-12 hours. So that places the Apple system on a 25-36% better battery range, instead of 80-100%. And still, there are more catches: Apple is probably driving the screen at 60Hz instead of 120Hz for the G14, and the screen tends to be one of the main drivers of battery life. What I'm trying to say is that the talks revolve around the M1 vs x86 for battery consumption, but the big savings can probably come from other components in the system.

      mWh? Otherwise that's one hell of a battery.

        Oops I missed my edit window! That'd also be some insane power consumption! Let's pretend I'm not from the U.S.A. and the comma is used as a decimal.

Or the coolness (lack of heat). I bought a laptop with an AMD chip once, never again. Thing was a fire hazard.

  Gotta be more specific when you say AMD chip. Was it a newer Zen chip or one of the old ones pre-Ryzen?
