Taiwan Semiconductor Manufacturing Company has started shipping its microprocessors to Apple as of this year’s second quarter, The Wall Street Journal reports. There have long been reports of Apple using TSMC for its chips in order to decrease dependence on Samsung, which previously manufactured all the microprocessors for Apple’s smartphones and tablets. It’s unclear how many chips TSMC has shipped thus far; Apple will still use Samsung for some of its microprocessors for now. TSMC and Apple will continue working on “more advanced chips” next year, a source said. A previous report claimed TSMC would make A8 chips for this year’s new Apple devices, and would start producing A9 chips in this year’s third quarter for future iPhones and iPads.
