The comparisons Digital Foundry have done lately has been to show games looking their best on the PC while at 4K (minus running games with mods etc). By doing this they've been able to show how the consoles compare against each other and the PC at it's best.
IIRC they haven't attempted to match the Xbox One X's graphical settings with a system equipped with an RX 480/580 8GB outside of testing Killer Instinct before the Xbox One X launched.
What features do you mean?
I mean I would love for them to do a comparison with 480/580 and 1060/70/80, although I am oversimplifying it cause i suspect it depends on the game engine and developers, just so people who are not tech savvy with PC like myself can know the strengths and weaknesses per game again I'm simplifying it but is it stronger than a 480/580, 1060,70,80 etc and why vs that game or basically do a benchmarks vs those cards, I don't like misinformation, there is a lot of fanboy stuff about the X some for and against vs pc and is like to see for myself, so far I have been very impressed with my X with my 4k HDR tv
