iPhone 4S Beating Galaxy S II in CPU Performance? Think Again

Today there has been a lot of misinformation going around the Internet. It all started with the otherwise reputable Anandtech tech reviews website, which actually may be a bit at fault too here for starting all this, but most of the blame should really go to everyone who has read this information ALL WRONG.

Here's what happened. Anandtech did the Sun Javascript benchmark to compare the "CPU performance" of the 2 phones, the iPhone 4S and Galaxy S II. But one thing he forgot to mention is that benchmark usually depends a lot more on the software than it does on the hardware. So when everyone saw the benchmark above, they thought that a dual core 800 Mhz A5 CPU can be almost twice as fast as the dual core 1.2 Ghz Exynos, which would be completely wrong.

The browser in Android 2.3 hasn't changed much at all since when it arrived in Android 2.2 with the new V8 Javascript engine. It wasn't until Honeycomb when they changed it with an improved one. And surprise surprise, Honeycomb's browser scores about the same with an even weaker CPU than Exynos. So why then is everyone, not only Apple fans but also Android website authors who are promoting this information over and over again on the Internet, instead of debunking it?

If you take a look at this site right here, you'll see that Galaxy S II should in fact be significantly faster than the iPhone 4S when it uses a more current browser like Firefox or Opera Mobile. You can expect the upcoming "stock" browser in Android 4.0 ICS (possibly the Chrome browser) to be even faster than that, making Android's browser perhaps twice as fast on a GS II than on an iPhone 4S.

Besides the older browser and older JS engine, one other reason why the Android browser may not be as fast is because it apparently doesn't use both cores, which is unfortunate, and it's a shame that Google didn't enable that since Android 2.3 (Opera and Firefox seem to use both).

So iPhone 4S may get to have some bragging rights for a couple of weeks (undeserved), but once Nexus Prime arrives with Android 4.0, and all future ICS phones, should be significantly faster than iPhone 4S, and that's a long time to wait until July-October next year.
