Scorpio wont do native 4K in most AAA games, its basic math

[Ruler]

PS4 Pro = 4.2TF

Xbox Scorpio = 6TF  (42% more powerfull)

 

PS4 Pro 1440p = 4,953,600 pixels

4K = 8,294,400 pixels (67% more pixels)

Now of course people argue its just the GPU and the Xbox One has more ram and better CPU but so does the PS4 Pro with 2.1 ghz CPU, all what Xbox Scorpio has is more ram from 8Gb to 12GB. But i doubt this is enough to give true for 4K, GPU is mostly important to get a higher resolution, the Xbox One will probably hit 7 million pixels maybe 7.5 million pixels but this is still not enough to get true 4K which is 8.3 million

Meanwhile you have all these people and sites going around saying that the Scoripio will do 4K 60fps, it wont even do native 4K
