As we inch our way towards the public release of iOS 7, we are treated to a rather interesting benchmarking video courtesy of YouTube user adrianisen. The clip showcases two different benchmark tools running on iOS 7 Beta 3 on both the iPhone 4 and iPhone 5. It's not clear why the tester chose the standard iPhone 4 as opposed to the more powerful 4S, but it certainly makes the performance difference between the two handsets remarkably apparent.
An interesting note: Using Geekbench 2, the iPhone 5 used in the test scores a 1,672 with iOS 7 Beta 3, while my own iPhone 5 running iOS 6.1.4 tops out at 1,664 consistently. It's a small increase, sure, but a promising result regardless. The iPhone 4, on the other hand, doesn't even break the 400-point barrier.
