I imagine it has to be 352 GFLOPs, would it even be able to run Black Ops 2 on two screens (albeit one is the lower res tablet screen) at 170-ish GFLOPs? That's below the 360.
Still Nintendo should've just said "screw this" and made a proper 60 watt system (still plenty power efficient and could be reduced down to 33 watts over time) and blown the doors off the 360/PS3.
They made the mistake of making the system far too close to the cheaper 360/PS3.
