They say the A6 processor has some cool tricks up its sleeve.
They A6 processor doesn’t have sleeves, but it does have some interesting performance variations. No sleeves, though.
Per The Unofficial Apple Weblog, one possible reason the iPhone 5 has such great battery life is the clever way the A6 changes its clock speed. While originally thought to be clocked at 1GHz, the chip has been clocked at 1.1GHz as well as 1.3GHz by Current Editorials.
While 9to5Mac saw the chip’s speed drop as low as 550MHz, this seemed to do more with an as-yet-updated Geekbench app testing the chip (which also resulted in the 1GHz assumption). A Geekbench update seems to paint a different picture now. By all accounts it appears the chip can change “speeds,” however, resulting in better battery life and dynamically tuning itself to the demand for CPU.
Nifty stuff…now if Apple could just release a much-improved iOS 6 Maps app, most of its problems would be over and it could sit and relax with a margarita this Friday.
