Nope. Anandtech measured 27W peak on M1 CPU workloads with the average closer to 20W+[1]. The Ryzen 4800U and i7-1165G7 also have comparable GPUs (and TPU+ISP for the i7) within the same ~15-25W TDP. The Intel i7-1165G7 average TDP might be closer to ~30W because of it's 4.7Ghz boost clock, but it's still comparable to the M1. The i7-1165G7 and 4800U have a few laptop designs with soldered RAM. You can get 17hrs+ of video out of a 4800U laptop with a 60Wh battery[2]. Also comparable with i7-1065G7/i7-1165G7 at 15hrs+/50Wh.

Wasn’t 27W for the whole Mac Mini machine using a meter at the wall plug? So that includes losses in the power supply and ssd and everything else outside the chip that uses a bit of juice whereas the AMD tdp is just the chip. I thought Anandtech said there was currently no reliable way to do an ‘apples to apples’ tdp comparison? Edit: quote from anandtech: “As we had access to the Mac mini rather than a Macbook, it meant that power measurement was rather simple on the device as we can just hook up a meter to the AC input of the device. It’s to be noted with a huge disclaimer that because we are measuring AC wall power here, the power figures aren’t directly comparable to that of battery-powered devices, as the Mac mini’s power supply will incur a efficiency loss greater than that of other mobile SoCs, as well as TDP figures contemporary vendors such as Intel or AMD publish.”

The M1 doesn’t use 24W, it uses 12-16 watts. https://www.anandtech.com/show/16252/mac-mini-apple-m1-tested/3 https://www.anandtech.com/show/16252/mac-mini-apple-m1-teste... (CPU, GPU + DRAM combined)
