Editor's note: After conducting a full teardown analysis of Apple Inc.'s iPad mini and iPad 4 tablets shortly after the devices hit the street Nov. 2, engineers from UBM TechInsights put the Apple A6X processoravailable for the first time in the iPad 4under the knife (and microscope).
Inside the new Apple iPador iPad 4lies a modified A6 processor dubbed the A6X. This modified A6 processor still features two application processor cores and operates at 1 GHz. However, the architecture has been modified to include quad-core graphics as opposed to the three-core graphics of the original A6.
At first, we suspected that this new processor would continue to feature the PowerVR SGX543 family GPU. But further analysis found otherwise.
