With now available for both the iPad 2 and iPhone 4, I tested to see how performance differed between the two devices. (Dadly, the original iPad isn't supported by iMovie.)

In this test, I opened a new iMovie project and imported a 76-second clip from my iPhoto library. I applied fade in and fade out transitions and added some music. I then exported the new iMovie project to the Camera Roll. The iPhone 4 took 87 seconds, while the iPad 2 took 56 seconds, which is 36 percent faster than the iPhone 4.

I ran four 2.0.3 tests on the iPad 2, iPhone 4, and the original iPad. The tests use two different scenes, one named Egypt, and the other named Pro that uses a prehistoric 3D setting. I ran the tests using full screen anti-aliasing turned on and again with full screen anti-aliasing off.

In these tests, the iPad 2's graphics screamed past the older iOS devices. The iPad 2 posted frame rates of over 45 frames per second in the Egypt tests and 57 fps in the Pro tests. By comparison, the original iPad was only able to eke out 8.1 fps in the Egypt test with full screen anti-aliasing off, and 6.4 fps with full screen anti-aliasing on. The original iPad fared a little better in the Pro tests, scoring 17.6 with full screen anti-aliasing off, and 13.6 with full screen anti-aliasing on, but the iPad 2 still was three times faster than the original iPad in the full screen anti-aliasing off tests and four times faster with full screen anti-aliasing on.
