> M1 is particularly spectacular when compared to other chips with similar thermal characteristics. i7-3770K has TDP of 77 W, without a GPU, so it has 7-8 times the power budget of M1 for the CPU.
Performance doesn't scale linearly with TDP, and that's always been the case. Take any laptop vs desktop CPU, and you'd see the same ratios at play.

Nonetheless, the M1 will most definitely be drawing much less power, its essentially an Atom processor after all. Its just gonna be hard to really put a number on it - even if you could read out the consumption from the BIOS, as they're doing things differently (integrated GPU and SSD controller for the apple silicone chips etc)
- dijit 4y ago> intel targets ~65°C are you certain you arent swapping these? Intel CPUs are famously running up to 100C before stopping their boost clock. One need only watch a single episode of Linus Tech Tips. people have reported barely any cooling requirements on the M1 and M2s comparitively.
- 411111111111111 4y agoYes, i'm sure. It would've taken you about 20 seconds to find it out yourself too, as the Intel 3770K has a published spreadsheet which clearly states the working temperature. The M1 doesn't, but there are enough unofficial sources to confirm the 100°C too. Including LTTs own video. Its a quiet old model, and consumer CPUs of that generation where generally targeting ~60-70°C. Nowadays they're all going for 95-100°C, wherever its Intel, AMD or Apple
- brigade 4y agoTcase is different than Tjunction. Tjunction has been around 100 since like Yonah at least.
- 411111111111111 4y agoBoth of your statements are true, but Tjunction isn't the target operating temperature. Tjunction is the maximum operating temperature after which damage of the chip becomes likely.
- brigade 4y agoIntel doesn't publish or even have a "target operating temperature" or "working temperature"; I have no clue what you're pulling that out of.
