It has to be 3x faster to match M1's efficiency given the TDP is 30 vs 105.

I could care less about efficiency, it's still 2x faster for 2/3x less expensive. Isn't the m1 max tdp between 60 and 90w?

Well yes but ones a laptop chip with a 17 hour life and the other I’ve got under my desk heating my entire condo lol

If you could conceivably run a chip at a much higher TDP before hitting thermal limits you could get significantly more performance. Not that you can (probably) OC these chips at all but it suggests there may be more rabbits in the bag.

You're comparing a single CPU with a complete machine

If you're plugged in all the time, lower TDP is nice but not critical. And if you live in a cold country, you have to heat up the house six months per year, TDP is just heating with a computing side effect.

Except it is still direct electrical heating which is atrociously inefficient.

This winter I'm going to experiment with having a Raspberry Pi act as a thermostat that starts/stops containers running on a server in our basement. That, combined with the laptop we just got for gaming that has a 3070 in it, should do nicely to supplement our heating system.

As someone who lives in south-east Queensland, Australia, lower TDPs and thermal output is always welcome, at least for me. I adore my Ryzen 5600X/3060 Ti mini-ITX desktop, but mining on it makes my room annoyingly warm, and it's not even summer yet.

Was semi-useful in winter though, all 6 weeks of it...

"If you're plugged in all the time" then try the Mac Pro version when it comes out.

This is about performance in laptop models, where it IS critical.

A hot laptop can have significant impacts on fertility in men. And in the summer you have to dissipate that heat. A heat pump is more efficient for heating, to boot.
