(This is not to undermine the fact that the M1 is a /great/ chip, but the 10W figure is a marketing number.)
>It’s especially important to keep in mind that the figure of what we usually recall as TDP in processors is actually only a subset of the figures presented here, as beyond just the SoC we’re also measuring DRAM and voltage regulation overhead, something which is not included in TDP figures nor your typical package power readout on a laptop.

Running those tests on the XPS 13 would typically cause the fan to turn on after a minute or two if I remember correctly.
As I said, the M1 is a /great/ CPU. But the numbers are marketing numbers & should be treated as such. The same goes for the CPU in your XPS. It was sold with an advertised TDP, was probably configured by the manufacturer to a /different/ TDP target subject to the thermal constraints of the laptop & as an end-user you can shift the set-points of thermals vs power consumption yourself if you want to. None of this is new & Apple is no exception. If Intel hadn’t completely failed to deliver their last 2 fab shrinks, you’d be sat here raving about how amazing your passively cooled Intel Mac was I imagine.
