... while unplugged ... Nothing new here, this is just better 5nm process advantage (which M2 undoubtedly has).

“There are three kinds of lies: Lies, Damned Lies, and Statistics”. I really wish thermal throttling was the first major point of discussion for ALL laptop CPU's. One of my work laptops never reached full cpu speeds in the real world because it would get thermally throttled!

  And in the case of M1/M2 Airs it's quite contrary - you need to load them really hard to cause throttling. With Apple Silicon MBP I’m not sure what level of load should be to cause throttling with full-speed fans.

  I had the same experience, and it's incredibly frustrating -- both when you don't know about thermal throttling and when you do. I'd do something that caused high load, and it would be briefly fast then suddenly everything would get sluggish. I naively thought this was normal ("under load") until some time I was doing the same workload on a similar-spec desktop CPU and it didn't happen. In trying to discovery why is when I first learned about thermal throttling.

    At least with windows you can turn off turboboost and other such features that basically temporarily overclock the cpu beyond what the thermals are designed for evidently. I had a late model intel mac that was horrible for this. Games would become unplayable because you'd have 30 seconds of reasonable FPS followed by 5 seconds of terrible awful drops then right back to reasonable fps. My 2012 era mac was better in this sense because the thermal design allowed the CPU to go all out at room temp, no throttling at all and consistent fps from the game (albeit low because of integrated graphics, but consistent nonetheless which is at least playable).

  > I really wish thermal throttling was the first major point of discussion for ALL laptop CPU's. Exactly. Intel claims performance leadership based on their P series chips, which are always going to be throttled in a slim and light laptop. For instance, Lenovo's thin and light ThinkPad X1 Yoga has two fans but still throttles: >Unfortunately, the laptop got uncomfortably hot in its Best performance mode during testing, even with light workloads. https://arstechnica.com/gadgets/2022/07/review-lenovos-thinkpad-x1-yoga-gen-7-looks-good-but-feels-warm/5/#h2 https://arstechnica.com/gadgets/2022/07/review-lenovos-think... Or the Dell XPS 13 Plus: >the XPS 13 Plus’ fan was really struggling here because, boy oh boy, did this thing get hot. After a few hours of regular use (which, in my case, is a dozen or so Chrome tabs with Slack running over top), this laptop was boiling. I was getting uncomfortable keeping my hands on the palm rests and typing on the keyboard. Putting it on my lap was off the table. https://www.theverge.com/23284276/dell-xps-13-plus-intel-2022-review https://www.theverge.com/23284276/dell-xps-13-plus-intel-202...

  My old work laptop was an i7 XPS-13. On bootup, it would spam the console with messages about the processor cores thermal throttling (partly due to cpu load from disk encryption)-- this was within a few seconds of power on in a too cold air conditioned office.

It's going to be partially this, but with AMD launching Ryzen 7000 mobile on 5nm we can see how close we get in performance per watt. I don't believe it will be enough to catch up. Also remember this is running in a VM (guaranteed overhead) and Windows for ARM (this is the red head step child of Microsoft). Even if they closed the gap, this is still impressive.
