iPhone 4S A5 Chip Clocked at 800Mhz, Trumps the iPhone 4 and Competing Android Smartphones in Overall Performance

As you all know, Apple's iPhone 4S is currently one hot topic among the tech industry. The iPhone 4S is a significantly souped-up version of the iPhone 4 boasting a Dual-core A5 chip, highly improved camera and video, longer battery life and many other improvements. But in terms of performance, how well does iPhone 4S stacks up against the iPhone 4 and all other competing smartphones in the market? To answer your question, here are a couple of iPhone 4S preliminary benchmark numbers.

iPhone 4S A5 Chip
The said benchmark was done by AnandTech, a website dedicated to hardware coverage and is known for their in-depth reviews, to which they posted a report that discussed many different benchmark scores of the iPhone 4S and how it stacks up with the iPhone 4 and other smartphones in the market including Android devices such as the Samsung Galaxy S II and Motorola Droid Bionic.

There were no doubts that the iPhone 4S would perform admirably in terms of overall performance but if these benchmarks are of any indication, Apple's latest iPhone is actually better than most major smartphones that are out in the market, topping almost every benchmarks that was performed. Check out the benchmarks below:
iPhone 4S Benchmark Javascript
iPhone 4S Benchmark BrowserMark
From AnandTech:

The results are pretty much as expected. Javascript performance finally catches up to Tegra 2 based Honeycomb devices, while general CPU performance is significantly higher than the iPhone 4. I suspect Ice Cream Sandwich will bridge the Android smartphone gap (the Honeycomb equipped Gtab 8.9 is here to give you an idea of where a more modern Android browser ends up).

AnandTech advises that the tests that was performed measures the performance of the software along with the hardware. For the web browser tests, it depends on how well browser optimization is which is the reason why there is a good number of differences between similar hardware that runs different browser versions. AnandTech also noted that the results were run using stock hardware and specs together with stock browsers on each devices.

Another interesting thing to note on these tests is that according to the results from Geekbench, it was found out that the iPhone 4S's A5 chip was actually underclocked to 800Mhz. So based on the tests, the iPhone 4S is slower than the iPad 2 which in comparison has 900Mhz. This is quite obvious and understandable since the iPhone 4S packs a smaller battery than the iPad 2. So Apple was thinking along the lines of preserving battery life rather than going for all-out performance. Definitely a smart move for Apple.

But despite being underclocked, the iPhone 4S was actually able to beat the competition by a considerable margin. And in some cases, it has even managed to be comparable with the Samsung Galaxy Tab. Yes, the iPhone 4S is going toe-to-toe with a tablet device.

iPhone 4S Benchmark GLBenchmark_2
As for the graphics test, the iPhone 4S manages to come out on top as well using GLBenchmark 2.1, just lagging behind the iPad 2 which is again can be attributed to the difference in clock speed. Also worth noting is just how the iPhone 4S manages to dwarf the current iPhone 4 both in terms of graphics and overall performance.

To be fair, AnandTech did point out that the current gap between the iPhone 4S and the Android devices such as the Galaxy S II may be bridged once Google's upcoming Ice Cream Sandwich is released. Expect to see more benchmark tests once the iPhone 4S becomes officially available this coming October 14th.
