I can tell you it is most definitely not as good. It does not display retina apps at full resolution as on the iphone4, and it also still does not display HD movies/video. So no, not as good. To me, it is the exact same as my iPad 1, probably because it is. Haha.
Now the video processor on the otherhand, that is better, which does help the overall look of things. But resolution, no different.
