Benchmark information from AppAdvice.com
If the results of benchmarks run by Tim Chaten at AppAdvice are any indication, anyone looking for a good, fast iMovie workstation for doing editing in the field should take a close look at the app running on an iPad 2.
Chaten wanted to see how iMovie for iOS running on the dual-core A5 iPad 2 would stack up to the Mac OS X edition of the app running on a variety of Macs, so he took a set of files to an Apple Store to run three tests on all of the stock Macs in the store with the exception of the Mac mini. The results were astonishing.
In the first test, copying a two-minute test video shot on a fourth-generation iPod touch to an iPad or Mac, the iPad 2 was the hands-down winner. It copied the files in just 25.5 seconds compared to 56.5 seconds on the fastest Mac -- a Mac Pro.
The second benchmark encoded an unedited movie to 720p. Once again, the iPad 2 bested the rest of the Apple family by speedily encoding the file in 1 minute and 56 seconds. The fastest Mac in the bunch (hardly a portable machine) was a Mac Pro at 2 minutes and 15 seconds, while the fastest laptop was the 17" MacBook Pro; it timed in at 2 minutes and 20 seconds.
