No 1080p on Xbox One Due To Memory Bandwidth/ESRAM/RAM

I don't think 1080p will magically become nothing on the xb1, except on games with simple graphics... because of the eSram size, you just can't fit that much in there. While on the PS4 it's already pretty much a given, since the release of the console we only had two (Battlefield 4 and Watch_Dogs... 3 if you want to nit pick and count the multi-player portion of Killzone:SF... that's it!) XB1 on the other hand it's hit and miss, about 50% of the games are sub 1080p, exclusives or no, I would not expect it to change much.

I wouldn't even count KZ multiplayer because the frame still is 1080p, just combining a partial new frame with an old one. BF4 was a broken mess and WD has terrible optimization on any platform, so in the end the console can handle it if the game isn't simply a bad version.

About X1, there is the tiling update to the SDK that will allow to divide a 1080p frame in parts and send one at time to the ESRAM. Anyway, how much of a performance impact it will have is unknown, but it certainly won't be a free lunch. Our infos says that PS4 has 50% more raw power and that is pretty on part with 1080p X 900p since you have 50% more pixels and the amount of power needed to increase resolution is close to the actual pixel increase (since most demanding graphical operations are done per-pixel: lightning, AA, etc).

If the tiling thing solves the issue, I'm counting on more 1080p games but with simpler visuals compared to PS4 (less AA, less light sources, less texture filtering, etc) or with worse framerate, but time will tell what will happen in this case.
