Can a monitor's resolution affect GPU benchmarks?

For example, testing 1440p performance on a 4k monitor. Even though the gpu is rendering at a lower resolution it still has to send information to the same number of pixels, right? Been wondering about this for a while now.

it would be so insignificant, it likely doesn't matter, if you want to try, turn your monitor itself to different resolutions and test how they affect scores.

I wish I had a way of testing it but I don't. There's tons of videos on youtube comparing performance at difference resolutions but I expect they're just using a 4k monitor and lowering the in-game resolution for each test, so it would be nice to know just how accurate that is vs using a monitor with that actual resolution.

Results should be identical. If you're running at 640x480 full screen, the video card isn't doing the upscaling. The monitor is.

Now in some circumstances, like on AMD cards (I don't think Nvidia can do this), the video card will do what's called integer scaling. That means if I drop the resolution down in the game, it will only use the center portion of the monitor. This is great for old stuff that's designed for a 3:4 or 4:5 ratio monitor. Looks nice and crisp, and it's the correct aspect ratio, despite being slightly small on the monitor

For example, on one of the greatest games ever made (fight me):

Isn't everything on the shoulders of the gpu? I'd expect that running in windowed mode would give identical results but that's not the question I'm asking. If a gpu is rendering a game at 1920x1080 but is being displayed on a 4k monitor, the gpu still has to send information to every one of the 8,294,400 pixels. I expect it's very little load on the gpu but would nevertheless be interesting to know how much, if any. Just want to know how it all works.

Nope. Plug your monitor into an old 1080p Blu-Ray player, it'll upscale the output to fill the whole screen. GPU just needs to output the set resolution you've made in the driver.
