AMD vs nVidia Colors - Concrete proof of differences

[XoR_]

For those seeking more infos on this subject, just google “NVIDIA vs AMD Color Quality” and “NVIDIA vs AMD Image Quality”. Read every threads, forums, websites, and comments you’re able to find.

After reading every thread and comment nothing else to do than take old trusty shotgun and shoot oneself in the...

To truly put an end to this 30-years old doubt/argument once and for all, we’re gonna need side-by-side comparison videos and screenshots between RTX 4090 & 7900 XTX on a modern 4K OLED monitor with same DP/HDMI cable, same monitor, same monitor settings, same driver, same driver settings, same game, same in-game settings. Let’s see if there’s still any noticeable visual differences after all.

I'd take proper measurement using color probe. It is possible to show without showing pictures that eg. one GPU shows things differently than the other eg. has banding with settings where other GPU still looks fine, or that gamut/gamma is the same, etc.

Only thing which cannot be proven is existence or quality of any additional filters like sharpening - though no one is fortunately claiming anyone uses such filters so such comparisons are not needed.

I don't have a colorimeter/calibration device nor an AMD card with me to conduct tests. Did you find any difference from testing both vendors (same settings) on your monitor?


Tech Yes City did a comparison years ago and he didn't find much noticeable difference, only one game.

What about the QD-LED displays these days?

That's basically Apple's version of QD-OLED. Would need colorimeter/spectrophotometer to measure color-contrast outputs between GeForce and Radeon on such display.

Games can have different optimizations or paths in code for different GPUs which can introduce differences. This is all digital, all math and logic -> the calculations per pixel should be the same. If AMD or Nvidia compression methods for like color are not loose less then some errors can be introduced. In addition where mipmaps, LOD can also be different for the different resolution textures.

In a nutshell -> very doubtful and at most insignificant. Since I cannot tell, even on an OLED, that is if I can get perfect gamma, color saturation, brightness/contrast which can also be slightly different. Now what I can tell is Nvidia does VRR on my Sony TV and AMD does not which is a significant gaming experience difference.

Which AMD card?

That is extremely odd that Nvidia can do VRR and AMD cannot. Are you speaking of VRR only, no Gsync or Freesync on that TV?

Which AMD card?

XFX MERC 6900XT. Works fine on the LG C2, have not tried it on the Samsung.

Yes, Sony only supports VRR and not GSync or Freesync officially. I and others at the AMD forums had this same issue. Nvidia just works in this case.

I know you are right but, AMD does support VRR as well, just not on that TV, apparently.
