What would worry me is if Apple came out with something like this Android device
CPU doesn't push pixels or really have much impact with gaming. A good CPU only come in handy with heavy physics calculations, advanced AI and tons of enemies onscreen. It can
try to take over some of the rendering load if the GPU becomes overburdened, but in that case it tends to overheat and doesn't do a very good job.
I think, with retina taken into account, the vita and iPad 4 are about equal. But the iPad doesn't necessarily have to push full 1536p...
