The one I've personally benchmarked is an unreleased application by a group of people I know, however it's very far along and (IMO) could be released today. The iPad 3 performs more poorly compared to the other platforms across several metrics.
Do say if the app is sloppy programmed or really needs the faster CPU to do the work. We're programmers here, well, most of us. Anyway note that up to recently you needed two graphic cards and in the desktop and the two monitor cables just to be able to connect the screen with the resolution of the iPad 3. http://youtu.be/KpUNA2nutbk
