iPad 2 Benchmarks (with comparisons)
Just incase anyone was interested, I ran benchmarks against the iPad 2.
Geekbench seems like the only legitimate benchmarking suite for iOS, so it was used to get these numbers. Numbers don't really mean too much, but in app performance and launch times of traditionally heavy apps like X-Plane seem to be much quicker.
These numbers are after clearing all background processes and doing a full reboot.
iPad 1 (AT&T/64 GB/4.2.1): 420
iPad 2 (Verizon/64 GB/4.3.0): 748
EDIT: Seems like I can't link to the full benchmark result pages because I just joined this forum, but you can find the links to the full results (broken down by test) on Twitter user richrhee.
Since this is a cross-platform/hardware benchmark here are some numbers I got with some other systems for reference:
iPhone 3GS (32 GB/4.2.1): 278
iPod Touch 4 (8 GB/4.2.1): 375
11" Macbook Air (1.6 Ghz/4 GB): 2521
Windows 7 PC (i7-2600k/8 GB): 9312
Linux CentOS 5.5 (i7-930 Overclocked @ 3.83 GHz): 11413
