Is it possible a game @4K on Xbox One/Ps4?

Well, I want to know if is it possible to see games running at 4K on Xbox One or PS4.

If the answer is yes, what kind of games could be seen? Very simple games? PS2 level?

It runs at native 1080p at 60 frames per second - but that's just the beginning of the story. Frozenbyte's impressive Trine 2 has migrated to PlayStation 4 in fine form - not only does it combine the optimal mix of resolution and frame-rate, but it's the only game to support stereoscopic 3D, running internally at an effective 1080p120 in the process. Indeed, according to the developer, Trine 2 could even hit 4K at 30fps should Sony ever unlock the output of the PS4 to support ultra-HD resolution.

Thanks!

Then, a game like trine 2, with "Xbox 360/Ps3" graphics, could run @ 4K on PS4.

Can the tile rendering techniques "allow" higher resolutions in a tiled based engine?
 
Of course it is. Just depends on how far you want to dial down the graphics...

Probably it would be something like the equivalent of 1080P games this gen, just a very select few. If anything, less supported. We had some 1080P games at the beginning of last gen, no 4K console games today...

4K TV adoption is well behind where 1080P adoption was in 2005 as well.

Tiling was necessary for high resolutions on the 360 because Xenos was required to render into a 10MB eDRAM pool. You had to break large framebuffers into small chunks, because the entire buffer wouldn't fit into 10MB.

The pool that the PS4's GPU renders into is the console's main GDDR5, which is over 800 times larger than the 360's eDRAM.

The Xbox One would have a little more trouble, because the eSRAM is only half the size of even a wimpy 64bpp buffering scheme at 4K. Though according to what Microsoft has said, you can render out to the DDR3 (and even share a buffer between the two pols), so strictly speaking tiling would be unnecessary (though the DDR3 bandwidth could potentially hurt performance relative to PS4).
 
Unless there's HDMI 2.0 support magically waiting to be unlocked, nothing is going to get higher than 30Hz sent to the TV. And I'd say 1080p w/ AA would look better than native 4K, since you aren't using as much memory bandwidth.

Yes. That should be fairly self evident. If the hardware is 10x faster, but the game is the same as ten times slower hardware, there'll be plenty of room to up the resolution.

Tile rendering can save on bandwidth in some renderers. It doesn't address any of the other problems with targeting higher resolutions, which is why it isn't a de-facto standard for games - if it was a 'magic bullet', everyone would be using it.

The way to get any resolution from any hardware is to only supply it with whatever workloads it can render at that resolution. You also have the option to render less or simpler graphics. So 4k is possible - it'll just require graphics somewhere between Pong and current-gen, and common sense would tell us last-gen graphics at 4k would be a natural fit (potentially slightly better given better GPU architectures) or 2D graphics.

Given a complete lack of market for 4k, it's questionable whether anyone would want to target that resolution, so the most likely situation will be simple 2D games that aren't stressing the consoles having a 4k output. And that's only if 4k is supported in the display-out of the console.
