Nothing to do with NPUs, as far as I know, it’s down to the dedicated video stream acceleration that ARM chips have carried for a while.
In practical terms, Windows Hello unlocks noticeably faster, just like a phone with facial recognition does. It also disproportionately handles video playback more efficiently, given the relative overall performance. Nothing new, either, it’s all stuff Apple got out of their own ARM transition, but way underrated in how much of a moment-to-moment difference it makes, particularly for stuff like the Surface Pro and other hybrids, where you want to handle it on battery and use it more like a tablet sometimes.
Yeah, no, I get the spirit of the thing. I’m just saying that… well, for one that it wouldn’t be a bad idea if it worked, it just doesn’t at the moment. But more importantly that regulations don’t work like that. You can’t just make rules that go “hey you guys specifically have to run this software on a server specifically”. You can already run assistants locally using a whole bunch of downloadable models, it’d be a huge overreach to tell people and companies that they CAN make the software and run it, but only remotely. That’s just… not how rules and regulations are put together.
