The only thing which we officially know about the processor inside the iPhone 5 is that it is, according to Apple, much faster (up to twice) than the previous chip which was featured in the iPhone 4S. According to the alleged benchmark result above, an iPhone 5 purportedly scored a whopping 1,601, which is more than twice the score of the iPhone 4S (with one word of note: it appears that no iOS device has ever scored more than 800 in Geekbench).
We’re advising you to treat this with a usual dose of skepticism but, if the above results are indeed legit, Apple’s new A6 chip (about which we’ve recently learned that it is a completely custom SoC) outscores, as far as this particular benchmark application is concerned, flagship Android devices like the Samsung Galaxy S III (which scored 1560*, though the Jelly Bean update should push it back on top) or the Asus-made Google Nexus 7 (and its 1,591* score). The benchmark also seems to confirm the fact that the new iPhone has 1GB of RAM.
Update: Our own, global (quad-core) Galaxy S III outscored the one reported by 9to5mac. We got 1747, so keep that in mind for the context above (also, thanks ehismanj in the comments for his results). Our Nexus 7 scored 1380 and out global HTC One X scored 1447.
