AnandTech publishes the first SunSpider Javascript benchmarks for the iPhone 5. SunSpider measures Javascript performance which runs in web browsers.

Smaller numbers are better, so the final score of 914.7ms is better than all of the other devices on the chart and is the fastest SunSpider test they've ever recorded for a smartphone. The iPhone 5 is two and a half times as fast as the iPhone 4S (2250ms) and notably faster than the Samsung Galaxy S III (1442.9-1824.9ms).

Javascript is used as a measure of web browser performance, but the final score can be impacted by both the processor as well as the particular Javascript implementation on the device. Javascript is a common area of optimization due to its common usage on websites and may have been improved in iOS 6 which ships with the iPhone 5. AnandTech notes that the superior performance is likely a reflection of the Apple A6's improved memory subsystem.

Between this and the geekbench scores. This is gonna be a FAST phone. My iPhone 4 has been good to me, but this thing is going to leave it in the dust.

So all the spec whores will choose the iPhone 5 over the S Galaxy III right? Because they are spec-whores right?

How much of this is a result of the improved browser in iOS6? Engadget shows an iPhone 4s with a significantly higher score:
"1,748ms, versus 2,266 on iOS 5"

Big LOL at Android fanboys who say everything about specs and nothing about actual performance.

Just hope that my iPhone 5 gets here Friday instead of Monday!

It would be interesting to see if you under-clocked to to match the performance of the 4S what kind of battery life you would get then.

Planet earth.
Benchmarks dont make it or break it, especially since the last article Macrumors wrote got debunked by users posting higher benchmarks than Macrumors posted in the Samsung SIII comparison, thereby beating the iPhone 5.

Wake me up when Apple has a clue about customization and then I'll consider using an iOS based device.

Now what happen if they put four cores in ? they would put their competitor ashamed to the side. Kind from Apple to use only two core :D

Do they have scores for laptops to get a feel for how fast mobile phones are?
