The debate of 4K resolutions in gaming and when they will become standardized has been at the forefront of our industry for some time now.
With the advent of the PS4 Pro and the even more powerful Xbox One X, the answer to that question has looked to be “pretty soon” more and more every day.
However, apparently even the two “enhanced” systems don’t have enough specs to be able to support proper 4K specifications.
While speaking with gaming magazine Edge (July 2018, Issue 320), AMD’s Timothy Lottes mentioned that to achieve 4K resolutions for a game that looks like a regular PS4 title, at a frame rate of 30 FPS, a game needs about 7.4 teraflops per second.
Interestingly enough, though, both the PS4 Pro and the Xbox One X fall short of this requirement, with the PS4 Pro coming in at 4.2 teraflops, and the Xbox One X at 6 teraflops (which is likely why it’s able to squeeze out native 4K resolutions anyway, being closer to the expected requirements).

Personal note: that's not far off from what Cerny said to Eurogamer ages ago (8TF for native 4K, that's without bells and whistles BTW).
