While Samsung and Apple continue to compete, both in the marketplace and the courts, when it comes to devices, behind the scenes they continue to work together. Apple is one of Samsung's biggest customers of semi-conductors, and if reports are to be believed is about to become an even larger one.
Currently, Apple buys many components from Taiwanese manufacturer TSMC. But Apple has long been unhappy with TSMC's slow adoption of the latest 14nm (nanometer) manufacturing process. Currently TSMC can supply only chips manufactured with the older 20nm process. Chips made to this older process are larger, consume more power, and generate more heat than newer chips, so the advantage of moving to the tighter process is obvious.
Reuters New Service is reporting that Apple will shift some integrated circuit production from TWMC to Samsung in 2015.
Reuters also reports that Qualcomm will be shifting chip production from TSMC to Samsung, and is already working with Samsung on the designs for those chips.
