I don’t think “painting vs photographing a painting” is a terrible analogy.

A PC just PLAYING a 4/8K video (media file) would produce similar levels of heat and… with some work (because it’s different tech and the PC has all sorts of other things to worry about) could probably be happily passively cooled.

When the PC is “processing” 4/8K (as in, on a game), it’s not just showing a picture that moves a lot, it’s doing all the work behind drawing that picture to start with. Generally at 60 to 200 times a second.
