I would take 1080p, 1440p & 4k, medium, high & ultra settings where applicable (as that is generally where most people seem to game)
Use 3 different cards from each vendor so Vega 56/Vega 64/Vega VII & 980, 1080, 2080 and just see what they do.
Then do both out box RAM as they have and profiles to suit so 3600 C16 or something realistic.
That gives what real world performance is for gamers at their resolution and graphic settings.
The 720p tests are waste of time because we just don't game at that and I don't care about theoretical, I care about what it actually does at what I game at.
If the CPU is then showing that the FPS are within 5% then I am not worried.
