When Apple announced the iPhone 5, the only details they revealed about the new processor was that it was called the A6 and that it was twice as fast as the older one in GPU as well as the GPU. Rumors started circulating shortly afterwards that Apple was seemingly using the brand new ARM Cortex A15 cores for the CPU, being the first in the industry to do so. Turns out, that's not the case after all.
Thanks to some super sleuthing by AnandTech, it has now been revealed that Apple is neither using the new A15 nor the older A9.
