Samsung recently said that it is planning to have 64-bit chips in its own range of smartphones — turns out it may have had a head start.

Chipworks, working with iFixit, has torn down the iPhone 5s, allowing it to be verified that Samsung is the manufacturer of the A7.

There has been some speculation that the A7 would be made by Taiwan Semiconductor Manufacturing Company (TSMC), but this now appears more likely for the A8.

AnandTech has noted that a die photo from Chipworks (below) shows a dual-core A7 central processing unit (highlighted with the yellow border), while the area with the light-blue border reveals "four replicated blocks with some shared logic in between" — which is the "4-cluster" PowerVR G6430 graphics processing unit (GPU) from Imagination Technologies.

The M7 co-processor — designed to measure motion data from the accelerometer, gyroscope and compass — is separate from the A7, and is from NXP.

The A7 uses a 28-nanometer manufacturing process rather than the previous 32-nanometer tech.
