solid rumor: Nintendo Switch will be using Tegra X2

Tegra X2 would at least pull the memory bandwidth closer to X1, 50 GB/s vs 68 GB/s. X1 has the much faster esram to help out yet main memory would be more comparable.

It's just speculation anyway. Tegra x2 is 0.75 tflops, better than x1 at 0.5 tflops. Funny the Tegra X2 now also has Int8 compute, 3 dltops!

Drive PX2 can do 6 tflops / 20 dltops! (at 80 watts, 2x tegra x2 + 2x Pascal MXM GPU)

Anyway forget close to xb1 performance, the WiiU uses 34 watts total while gaming. The Switch also needs to power the screen and won't even use half that, doubt it can even power the x2 on battery mode. Maybe x2 has a low power mode for mobile?

What I can give Nintendo credit for is the very low power consumption. Where back in the day the PS3 and Xbox 360 used 160-180 Watts, the Wii only did 30 Watts and the Wii U like you said 34 Watts.

The PS4 is currently around 135 Watts and the Xbox One about 115 watts.

What power consumption the NS will have is only to be rumored. Both in handheld mode and home console mode.
