As already known, the A9 chips used by Apple in iPhones 6s / 6s Plus are manufactured by both Samsung and TSMC. Small differences between them even threatened to generate a #chipgate, but it ended up being dropped after analysis / testing.
According to (Google Translate) the Korean newspaper Electronic News, as of this year there will no longer be this type of controversy for a simple reason: Apple would have chosen Taiwan Semiconductor Manufacturing Company as the sole supplier of the next chip A10, saying goodbye Samsung.
The information matches recent statements from both companies. On the one hand, the South Korean had said she would have a difficult year ahead of her; on the other, Taiwanese already expects its production of 10 nanometer chips to accelerate considerably from the second half of 2016 until the beginning of 2017. This process will contribute to more performance, more energy efficiency and reduced manufacturing costs.
If this rumor really materializes, it will be a great achievement for TSMC, because great news is expected for the iPhone 7 and, once again, historical sales records. In keeping with the timeline of past years, Apple is expected to announce the device around September.
