@bold If you look up benchmarks, it's actually mostly 2-3x for 1080p to 4K UHD, depending on engine, API and GPU architecture.

Here's some of the latest for 1660Ti (link is for Metro Exodus, there are others games in review as well):

As you can see in the other part I bolded I clarified that. Yes in the real world you wont need 4x the actual physical total TF rating of a GPU to go from 1080p to 4k because the whole of the GPU isnt being used for the rez to begin with. But what of it is will usually scale directly t the chosen rez.

And if you look at that link you sent me and do the math... the only thing they changed was the resolution, the 2080 ran the game at ultra preset in 1080p at 76fps. When they switched it to 4k that dropped to 50fps. Thats about a 34% drop in performance. That doesn tell us what the part of the GPU that focuses on rez is actually using.

It's actually 79@4K and 39@1080p for 2080...so 2x drop

That's about what I would expect as a whole to be the difference in next gen going from 1080 to 4K...even AMD's offerings seem to hover around 2x in latest titles, which is pleasant surpise given that they used to drop around 3x when going to 4K.
