First I've heard of this but a quick search and this video title kind of answers the question on it's own. https://www.youtube.com/watch?v=xkct2HBpgNY Also not sure if still the case but just over a year ago Nvidia became my choice because AMD cards were way to high power consumption but that may not be the case anymore. I'm talking 2 or 3 times the consumption of same spec nvidia cards and I was limited since utilities are included in my rent and when 300 watts is listed as power consumption and the nvidia is around a 100 watts running straight out then the purchase is already chosen when looking for a card that does 4k right. Admittedly I was a moron using linux that should have gone Intel with onboard uhd graphics which are far superior in compatibility overall for linux. But this is for graphics upscaling on an image then get a copy of GIMP and then GMIC plugin also free and use the upscale and repair area filters to get amazing results rivaling photoshops paid plugins. Most do 4k but your questions seems more like 8k related. Also if for video make sure the FPS are right. My nvidia 1650 does 4k but only at 30 FPS so there is that for consideration also. Good luck.
