Some quotes about the gamepad effecting performance.
I said streaming an image to the gamepad is free, streaming a copy of what is on the tv is free (as confirmed by dev's)
Of course rendering a completely separate image is going to take additional resources, having a HUD in a game technically takes up additional resources but those things would have already been rendered in one form or another. For example, rendering a map on the gamepad should not take up more resources than rendering it on screen. However, a completely interactive 3d camera would obviously constitute a performance hit because it's rendering another 3d image, it should similar to the hit that 360 or ps3 games experience in split screen multiplayer.
I'm sorry if my previous comment was worded in a way that could be misconstrued but I was referring to the act of streaming an image being free (not rendering an interactive 3d camera or an animated overlay). there is apparently a dedicated memory pool on the chip for the gamepad's framebuffer so it is literally free.
The people on neogaf that did the GPU teardown have been postulating that there is hardware on the chip whose sole purpose is render and push out images to the gamepad. If this is true then the rendering of the gamepad image does not take up any more resources than it would take to render the same image on the TV screen. The entire gamepad framebuffer is free even though it's pushing out a 480p image. No resources would be freed up if you turn the gamepad off because the hardware that pushes out the image would just not be used.
Essentially there is dedicated hardware that handles the framebuffer seperately meaning that putting an image on the gamepad does not take up additional resources, unless you are pushing something that would not normally be rendered to the screen (like a second camera).
