Samsung Starts Manufacturing Apple's A9 Chip for 2015 iOS Devices
Samsung and TSMC have been competing for Apple's lucrative A9 processor contract after Apple in 2013 signed a multi-year deal with Taiwan's TSMC to supply A-series processors for Apple's iOS devices. TSMC took lead on the A8 chip, fabricating the SoC for both the iPhone 6 and 6 Plus. The Taiwanese company also reportedly landed the contract to produce Apple's A8X chip, which is found in the new iPad Air 2.
Samsung semiconductor head Kim Ki-nam last month confirmed the company would begin producing 14-nanometer processors for Apple in a supply chain deal that will have a positive impact on Samsung's profits. A report from last year suggestsed TSMC would replace Samsung as Apple's lead chip supplier, but Samsung's technological progress with its 14-nanometer process may have swung the pendulum back in its favor.
