If anyone was curious to know how the new Apple A7 chip is structured on the inside, the Canadian firm Chipworks has dismantled an iPhone to have one of those chips in their hand and be able to analyze it. As they say, they have not yet done any “circuitry” extraction that would support their suspicions. But seeing the inside of the processor in detail, you can get an approximate idea of what function each zone has.
As a first curious fact? The phone’s CPU occupies about 17 percent of the chip’s surface, which as you know has two cores. While the GPU occupies slightly more, about 22 percent of the total surface area and has four cores. With these two simple data we can sense the importance of graphics for Apple.
They have also been concerned with finding the area where the Touch ID information could supposedly be stored, and estimate that the space available will be around 3 MB of capacity to store the fingerprints. This is a chip designed by Apple, significantly superior to its previous generation, the A6.
