Apple's handmade A6 processor in the iPhone 5 clocked at 1.3GHz, updated benchmark reveals
Apple's handmade A6 processor that we find in the iPhone 5 is a fast little thing, but that speed might be the result of a higher core frequency than reported by the Prime Labs' Geekbench benchmark before, pushing up its cores from 1 GHz to 1.3 GHz now.
This was revealed by an updated Geekbench 2.3.6 result, with the new version coming yesterday to account for more granular processor frequency detection.
Prime Labs' John Poole commented: "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 1.3 GHz discovery prompted speculation yesterday whether the iPhone 5 goes into temporary overclock under peak loads, but Poole disagrees: "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."
