Apple's A7 SoC expected to be 20% more efficient, debut in 'iPhone 5S'
Along with predictions of a much rumored "iPhone 5S," KGI analyst Ming-Chi Kuo's note to investors on Thursday shed some light on Apple's new A-series system on a chip, expected to be called the "A7."
With each successive iPhone generation, Apple has introduced a new processor design that trumps the outgoing version in both efficiency and speed. The current A6 used in the iPhone 5 was the first chip completely designed by Apple in-house, and the forthcoming "iPhone 5S" is predicted to build on that architecture with a so-called "A7" SoC.
Kuo believes Apple's upcoming A-series silicon to be based on the latest ARMv8 architecture. In comparison, the A6 was built on a custom ARMv7 setup that doubled number crunching and graphics speeds, while shrinking die size by 22 percent.
