Here's a question - what part of the system handles the Gamepad's screen?

I ask for two reasons - one, I'd think there'd at least be some part of the GPU designed specifically for the graphics of the Gamepad, due to issues like latency. Two, the Gamepad has a resolution matching that of the Wii... could it actually be using the same parts of the chip that handle the Wii Mode of the Wii U?

Anyway, just a thought.
