A Japanese firm has repeatedly pointed to a proof of the potential use of Samsung’s A7 chip in Apple’s latest iPhone 5S. Earlier Chipworks’ analysis had also pointed to a chip-level connection between the 2 technology firms.
However, after a thorough dissection of the iPhone 5S by Nikkei Electronics, the team identified a Samsung made A7 chip inside the phone, CNET reports. As per the report, the A7 is Apple’s latest chip that is used in the iPhone 5S, iPad Air, and iPad Mini Retina and is the first 64-bit chip for use in a customer smartphone. Nikkei Electronics said that the A7 builds on Samsung’s 28-nanometer production process, which is more advanced than the 32-nanometer Samsung process utilized for the earlier A6 processor.
On the other hand, a source familiar with worldwide contract manufacturing relationships, disclosed that Apple had been dealing with TSMC (Taiwan Semiconductor Manufacturing Company), the biggest processor agreement maker on earth and Globalfoundries could also be a possible source of production, the report added.
