The iPhone 5 is Actually Clocked at 1.3GHz
Primate Labs' John Poole has released a new version of Geekbench for iPhone that features a dramatically improved processor frequency detection algorithm, reports Engadget.
The new algorithm "consistently reports the A6's frequency as 1.3GHz." Poole confirmed to Engadget that "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."
The site asked him if the A6 chip was capable of dynamically overclocking to which Poole answered, "I don't believe the A6 has any form of processor boost. In our testing, we found the 1.3GHz was constant regardless of whether one core or both cores were busy."
