"Switch is performance wise between Wii U and Xbox One"
I mean I guess thats true... even if its much closer to Wii U, than Xbox One.
Wii U - 176 Gflops.
Switch - 393 Gflops (docked)
Xbox One - 1300 Gflops.
Xbox One Slim - 1400 Gflops
Playstation 4 (&slim) - 1840 Gflops
We "know" how many Gflops the Switch is now btw.
Its confirmed to have a normal Tegra X1 chip in it, and its gpu is running 768mhz.
This isnt a guess, its a fact.
Switch is 393 Gflops.
Here is a gif of a Switch chip cut open (die shot) vs a Tegra X1: http://i.imgur.com/ogCFzAz.gif
Its a Tegra X1. Theres no debateing that.
