They showed the Unreal Engine 4 Elemental engine running on the Tegra X1 during its unveiling. This is the same demo used for PS4/X1 (not PS3, PS3 can't run that). At 10 watts (versus 100+ watts for the XBox One). 

They've also demoed games running on the Tegra X1 at 1080p, 60 fps. Not sure if the Wii U could run the same thing. I think the Tegra X1 is more powerful than the Wii U. 

To be honest I think if XBox 360 had double the horsepower it could run a lot of the X1/PS4 games ... at 540p. It's able to run things like Destiny and other PS4 ports reasonably OK. 


PS3 and 360 just can't run the themo because it uses DX11 resources, while they are DX9. You would just have to remove the DX11 specific resources and it would be fine.

Running a game at 1080p @ 60 doesn't mean much. They did it with Doom 3 BFG a port of a 2004 game that already runs at 60 fps on PS360. It isn't the same thing than doing that with a modern game.

Again, just decreasing the resolution won't magically make any game run. You can be bottlenecked in several areas. Destiny is more of a PS360 port than a PS4 port since it doesn't uses basically none advanced rendering technic. A better view would be Metro Last Light. The PS4 version is at 1080p @ 60 while the PS3 version is at 720p @ 60 and had basically all visual effects removed to the point it doesn't look the same game. From what we know, the PS4 GPU probably outperforms the one in the 360 by around 10 to 15 times, with 16 times more memory and more than 15 times more memory bandwidth, with a stronger CPU. Running a game with last gen tech and running something like The Order, Ryse or Shadow Fall us a completely different beast. You can't aim to the last gen ports, because in a year they will be done and everything will be new gen tech. If "by a lot" means running the games that are on PS360 too, it's correct. If it means games created with 8th gen techs in mind, wait for more 3 to 5 Tegra iterations.

About Tegra X1 specs, you can't take conclusions with what NVidia showed, because they only showed specs that are good for them. Floating point performance is a useless metric (or else a R9 295X2 with 11 TFPS would slaughter a Titan Z with its "meager" 8 TFPS). They didn't talked about bandwitdh, simply because that would make it look worse than 360 because both have the same bandwidth but 360 has ESRAM. The "octa-core" CPU is actually a quad-core one with a big.LITTLE configuration. It's memory is lower clocked than the one on PS360 too, using a low wattage version of DDR4 to power it.

About the Wii U, Tegra X1 has more memory bandwidth (as PS360 have too). The CPU battle is probably uo to grabs, but that's because Wii U uses a tri-core version of the Wii's CPU (that's a improved GC CPU by the way). The Wii U GPU is significantly stronger, tough. The biggest issue with the Wii U is that Nintendo didn't used scaled down current tech, but used older parts and after that managed to put ridiculous memory and CPU bottlenecks that should have made them fire their hardware design team.


I believe they ran Crysis 3 on the Shield. Resident Evil 5, Borderlands 2, and MGS Revengance is also apparently slated to be able to run natively on the TX1. If any of these games run at 1080p that's beyond what the Wii U is capable of IMO.
