The Wall Street Journal is reporting that Apple has finally escaped Samsung’s grasp of iOS device CPU production. Although Samsung lost exclusivity last year, there was still doubts that TSMC would be able to follow through with their contract. According to this report, the manufacturer has succeeded and started shipping next-generation microprocessors for Apple’s devices (likely adorned with the ‘A8′ nomenclature) in the second quarter.
This marks a significant point in the production of the iPhone, finally allowing Apple to distance itself from Samsung in such a key area of its devices. The A8 chips use 20-nanometer production processes, according to the report. This compares favorably to the 28-nanometer process used for the A7, which should give better power efficiency and performance per watt. 9to5Mac previously reported that the A8 would focus on significant efficiency enhancements, rather than raw compute performance.
