Original Geekbench benchmarks had revealed that Apple's new iPhone 5 is powered by a 1.02 GHz ARMv7 processor with 1GB RAM.
But it looks like iPhone 5's A6 chip is much more powerful as it has been clocked at 1.3GHz by a new version of Geekbench 2 - an iOS benchmarking app, that hit the App Store today.
Primate Labs John Poole told Engadget that the new version of Geekbench 2 app "features a dramatically improved processor frequency detection algorithm, which consistently reports the A6's frequency as 1.3GHz."
He said: "Earlier versions of Geekbench had trouble determining the A6's frequency, which lead to people claiming the A6's frequency as 1.0GHz as it was the most common value Geekbench reported."
Teardown of iPhone 5's A6 chip has revealed that it is powered by a dual-core CPU and triple-core graphics processing unit (GPU).
Performance tests carried out on Apple's dual-core A6 chip with triple-core graphics has validated Apple's claim that iPhone 5's A6 chip is twice as fast as iPhone 4S's A5 chip. The benchmarks have also determined that iPhone 5 is the world's fastest smartphone currently.
Performance benchmark results have also shown that iPhone 5's A6 chip runs at variable frequency, ranging from 800MH to 1.3GHz. Our iPhone 5 unit regularly displays 1.29GHz (it reported 1.10GHz initially), but as you can see above, a screenshot from an Engadget reader displays 1.30GHz.
