Power draw 4.41W 10.4W
second is touchscreen, what 'power draw' is is not specified (it is actually just a made up number as shown later), how many lamps and what kind of illumination panels have not specified.

didn't watch the videos, watched this reddit link. it literally actually proves the opposite of what you think. 4K has x3.54 more pixes than HD+, nikob would say "gpu does 3.54 times more work" but power consumption is only 45% higher. or it would seem so, because we are not done.
let's see these two laptops in actual controlled review, not someone's "opinion"

same cpu, same gpu, same battery size, 4K
has touchscreenreal battery life difference 12%, for screen with x3.54 more pixels and touch suppot
another proof that "4 more pixels = 4 times more work = 4 times more power consumption" isn't a thing
and keep in mind, it's a bad iris plus gpu that is maybe times weaker than modern igpus, for which desktop compositing is a free task nowaday. there's a recent video from Alex Ziskind that shows MBP GPU not giving a single f*** about up to 7 displays (only 4 or which are native), with 8K video running on two of then. It was even crunching AI bit faster with 7 displays, than it was with 1.
