iPhone 5 benchmarks reveal outstanding JavaScript performance

iPhone 5 benchmarks reveal outstanding JavaScript performance
That the iPhone 5 is faster than its predecessors is certainly true, given the fact that it has been equipped with a brand new Apple A6 SoC and 1GB of RAM. With its help, Apple claims that its new smartphone has twice the performance of the iPhone 4S. But in case you need a more solid evidence before buying into Apple's words, here is a benchmark score measuring the iPhone 5 JavaScript performance. Turns out that the iPhone 5 handles JavaScript not only better than the 4S, but also better than any other smartphone that has been tested using the SunSpider benchmark. Note that the impressive result was not only thanks to the smartphone's speedy A6 chip as iOS 6 plays an important role with its zippier JavaScript engine. 

What does all that mean? Well, some users might notice a performance boost when browsing the web thanks to the newer software and powerful hardware. Casual users might find the experience as smooth as it was with the iPhone 4S, since the predecessor delivers seamless web browsing performance as well. Chances are that we'll know for sure sooner than later, the moment we get our hands on an iPhone 5 and give it the review treatment.

i think sunspider is single-threaded so it won't benefit from more cores.

I have to say, this is highly impressive.

Agreed, I'm officially impressed! It may be only a Javascript benchmark, but it seriously seems that the new A6 cores are more performing than the Krait ones.

Its likely because the A6 uses true A15 cores instead of the rip-off that Krait uses.

You're actually wrong. The A6 doesn't even use an ARM reference core design, it's a custom Apple design that runs on a modified ARM v7 architecture to support a few custom instructions. Krait is like Cortex A15 but the pipeline isn't as deep because Qualcomm wanted to keep power consumption down. Krait v3 should give more performance though.

There is no true A15 out as of right now. Hell A6 isn't even like A15 chipsets.http://www.anandtech.com/show/6292/iphone-5-a6-not-a15-custom-core

A6 is not Cortex-A15. Phonearena confirmed earlier post

If you notice, every phone that beat the iPhone 4S in this benchmark test, came out AFTER the 4S was released, except for the Galaxy S II. So, it seems like once Apple releases a phone, it surely comes out near the top. It's their once a year release schedule that hurts them. If they were to make an iPhone every 6 months, they wouldn't have to be playing catch up. Wait and see how within the next year we'll see an army of new phones beating the iPhone 5 in this test. Happens every year.

If you notice, the iphone came out AFTER all those phones listed in the benchmark. If the S3 was to be released now, it would probably be running a quadcore exynos 5.

Well, if you don't mind me saying so: apple hit the spot again!

No sony in the benchmark? b**ch please!!

thats a darn nice score. What I find more interesting isnt that. Look down at the "Tmobile SGS3, SGS2, and ATT SGS3" The SGS2 mentioned uses the crappy old S3 crapdragon chip. And it outperforms the Crap Krait chip in the US SGS3 ATT and keep up with the Tmobile SGS3 which uses the same Krait chip. Wow.. all that "A15 equivilant" BS advertising and it cant even get past its old S3 chip which was the worst A9 dual core chip of the last generation. No thanks.

EDIT: Sorry, I thought it was the US sgs2 mentioned, its not, so its safe to say thats the international SGS2 which is Exynos 3 series based. It still proves the same point though. All that fluster and hub-ub from Qualcomm about how the Krait is "A15 Equivalent" (never believe a salesman) and it cant even get a real edge on a 45nm dual core chip from the previous generation. Yea.. no thanks.

Yeah the same crap krait chip is present in the HTC one S which is just below the score of the "international" Galaxy SIII ... Oh did we mention that it is a crap chip ??? its a pretty good one ..

28. Hunt3rj2

If you can't tell, you're being downvoted because the SGS2 mentioned is the international version with Exynos 4 dual and you're picking the wires for the worst possible score that Krait can get, because the Evo LTE is obviously 200 ms faster than the Exynos 4 dual in Sunspider. If anything, this just goes to show that browser optimization for SoCs is most important. The iPhone 5 likely has an architecture extremely similar to Krait, and yet it manages to blow by even Intel's SoC to take the Javascript crown.

yeh but as impressive as this figure is it dont tell the whole story, and that story is that overall the iphone 5 scored lower than the galaxy s3 which we all know was released months ago, its still impressive on apples behalf considering the clock speeds blah blah blah but its still not the full story sorry to say.

yup the GSIII was released sooo long ago, its unfair. Weren't companies comparing their devices to the 4S all the way up until the iPhone 5 was released. When the Galaxy S4 is released, its going to still be compared to the iPhone 5.
