I realize its apples to oranges and not applicable to the title of the topic, but back in 2020 I purchased a Radeon Pro W5500 for my new workstation and I can confirm that a) it uses no temporal dithering by default and b) It's a usable system under Linux with a good monitor, no noisy output.
Be warned. This is not a blanket recommendation for all AMD cards, and while I do not have any empirical data. I suspect something similar could be going on with recent Nvidia cards.
At least its encouraging that there are theoretically more "safer" cards than the usual picks here that can handle higher framerate applications and higher resolution monitors.
