The iPhone 4S isn’t even available to the masses yet, although a massive number of pre-orders have made this smartphone a record breaker in its own right. As for the select few who somehow have managed to get hold of the iPhone 4S, they have performed benchmarks on it obviously. In the presentation, Tim Cook mentioned that the iPhone 4S will boast the iPad 2’s A5 processor, sporting up to 7 times the graphical speed of its predecessor, so how does it fare in benchmark tests?Nothing out of expectations actually, where Javascript performance has finally caught up with Tegra 2-based Honeycomb devices, although it goes without saying that general CPU performance compared to the iPhone 4 is way higher, and with Google’s Ice Cream Sandwich update looming over the horizon, it ought to be able to do its part in bridging the Android smartphone gap. Also, don’t forget that a large part of the performance jump in Honeycomb comes from the Javascript optimization in the OS. The same thing is probably true for iOS 5 as well.
Despite having the same processor as the iPad 2, it is most probably lower-clocked after relying on the results of integer and fp tests that were published. This is not unnatural either, since the iPhone 4S comes with a far smaller 5.25 Whr battery and lower thermal dissipation capabilities.
