The Geekbench 2 app for iOS has been updated with multi-core processor support.
Geekbench provides a comprehensive set of benchmarks engineered to quickly and accurately measure processor and memory performance. Designed to make benchmarks easy to run and easy to understand, Geekbench takes the guesswork out of producing robust and reliable benchmark results.

You can purchase Geekbench 2 from the App Store for $0.99.
