Apple's chip future looks bright with first custom-designed A6
The iPhone 5 smartphone has the A6 CPU, which industry experts say is the first in a line of many upcoming Apple custom processors that will better balance performance with battery life in iPhones and iPads.
The custom-designed A6 core is a big step for Apple, whose previous A4 and A5 processors for iPhones and iPads were based on designs adopted from ARM. The A6 is also based on ARM architecture, but after analyzing code, chip size and the architecture, experts have concluded that Apple has designed its own CPU from the ground up rather than licensing an existing processor design.
It took a few years for Apple to customize its own CPU, but the company wants to control its own destiny, experts said. The new chip gives Apple top-to-bottom control over its smartphones and tablets, and ensures that the CPU and applications perform in tandem while preserving battery life in devices.
