iPhone 5 Javascript Benchmarks Over Twice as Fast

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

sunspider
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.

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

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

wake me up when fandroids will stop wasting their time in a forum called macrumors.

You do realize that its individuals like YOURSELF that instigate these kinds of 'brand wars' in the forums? Do you find meaning in life by being having an Apple logo or other attached to your character?

most of us don't worship apple, we just like their products, and this is a forum to discuss stuff. It's pretty crazy that you have an account to talk about products you loathe. I'm not sure what it says about your mental well being.

So, you'd rather turn a blind eye at the fact that Apple purposely limits even the slightest bit of customization? Do you oppose CHOICE?

I would consider "slightest bit of customization" to wallpapers. which we have. I know its "widgets" that your referring too but I mean......I can click on the weather app if I need to see the weather. I don't need it on my home screen.

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!
