gpu's use more power depending on the resolution

[GoodEnough]

i was just curious to why gpu's use so much more power when running in 4k instead of 1080p

 

normally my gpu's tdp is 150w but whenever i run something in 4k my gpu gets thirsty af and eats up 230w, i just thought that this seems fairly out of the ordinary for an rx 580.

Higher resolution means more pixels, each of which need to get rendered.

More pixels=more calculations=more power used.

i understand that, but for that much of an increase in wattage?

The graphics card has to push about 4 times as many pixels for 4k.

well yes, but actually no, as i am using vsr.

 

i wouldnt push the resolution so high if i didnt have to but games like destiny 2 and ark look like actual cancer at 1080p.

It's been awhile since I've looked into VSR, but if I remember correctly it renders the game at the higher resolution, then rescales it down to the resolution of your monitor. In this case the game would still be rendered in 4k, just scaled down to 1080p.

my computer is weird and does whatever it wants, i set it to 4k but then my computer goes "no" and sets it to some weird funky resolution close to 4k, so we can just pretend its 4k. im just that one person that does things with hardware that he really shouldnt try to do, like letting a ryzen 2600 hit a temp of 110c.

 

i have even had a bluescreen bluescreen on me before.
