[SOLVED] Performance difference between 1080p vs 1440p vs 4K

[Gintama69]

Just googled "fps difference between 1080p and 1440p" and the first answer that pops up(from Linus Tech, April 2017):
"1440p is 1.77 times as many pixels, so the FPS will be roughly 1/1.77 as much compared to 1080p (around 56%). Plus or minus some margin of error. The 1080 Ti will get more than double the FPS of the 970, so that should boost you up to a little higher than what you get right now "

So according to Linus Tech, performance difference between 1080p and 1440p is around 56%.
But according to my test, that's totally incorrect.. cos I get:
9.2% - 22.6% performance difference(depends on quality setting) between 1080p and 1440p on CoD MP.
33.3% performance difference(at highest quality) between 1080p and 1440p on Borderlands 3 benchmark.

My Results (i9 9900KS, MSI RTX2080Ti Gaming X, 32GB DDR4 4000 RAM, NVidia 441.66 driver - everything at stock speed)
CoD MP (Average FPS using MSI Afterburner & Rivatuner Statistics Server after 5 consecutive MP match at selected resolution/settings)
133fps - 1440p highest(rtx on) -

Difference in performance percentages will depend on the hardware involved.

I saw the thread you mean. It's just an estimate number. Between the system in question over there and yours, there is a huge difference. Think you're reading into it a little too literal don't you think?

You are assuming the only limiting factor is the gpu and everything will scale accordingly. With a 2080Ti at 1080p I would strongly expect you are cpu limited. The relatively small difference in COD with low settings at 1080p and 1440p supports my theory.

Ok, I understand your point.. but it's not like I'm running on 5+ year old out dated CPU, I've upgraded from i9 9900K to 9900KS recently. i.e. fastest gaming CPU money can buy.
And the two games I tested so far are also latest AAA title games, so Linus Tech's 56% difference sounds like a total bs, unless I'm supposed to test it on 7+ year old game with sad graphics like CS GO for accurate results.

Anyway answer happen to know the answer to my simple question?
Performace(average fps) difference between 1080p vs 1440p vs 4K? (at least roughly)
Thanks

Look at Techspot reviews for your card. You'll get an idea.

Linus’ video is a theory based on pure numbers not taking into account other factors. It’s just to illustrate a point on how demand on the gpu increases assuming no other limitations.

It is largely accepted that at 1080p a 2080Ti is just overkill whereby even the best CPU’s will be a limiting factor long before the gpu.

Use your new found numbers and calculate it yourself.
