Adding to all the usecases listed by other commenters.
Having a higher performance per watt numbers also implies less heat from M1's perspective. This means that even if someone isn't doing CPU/GPU heavy tasks, they are still getting better battery life since power isn't being wasted on cooling by spinning up the fans.
For some perspective, My current 2019, 16inch i7 MBP gets warm even if I leave it idling for 20 - 30 mins and I can barely get ~4hrs of battery life. My wife's M1 macbook air stays cool despite being fanless, and lasts the whole day with similar usage.
The point is performance per watt matters a lot in a portable device, regardless of its capabilities.
Try disable turbo and search around there is an utility that keep no turbo and using hours still 50 degree.
I am not associated with that guy. In fact I bought one for even my macmini. Get my m1 macmini to avoid all these hot air.
If you run biotcamp windows has registry to disable that and also system setting to limit to 99% (but seem still hot) for my playing with Vr and fs2020 using external egpu.
