In recent years, Apple has been able to fully open its CPU chip design, and the A12 bionic chip continues this trend and is reflected in the performance of the iPhone XS. Of course, although Apple designs these chips themselves, they are not responsible for production. Since the 2016 A10 chip, TSMC has been the exclusive supplier of Apple chips.
According to Digitimes, TSMC will continue to supply the iPhone's next-generation A13 processor exclusively next year. Apple has publicly praised TSMC for its ability to mass produce high quality products. At the Apple conference last month, Apple claimed that they were the first mobile phone companies to use 7nm chips, thanks in large part to TSMC's capabilities.
According to the report, TSMC accounted for 56% of the global OEM market in the first half of 2018, which is not unrelated to the company's cooperation with Apple. Some analysts expect that TSMC's market share will rise further next year.
However, there is no detail on how the A13 will be upgraded in terms of performance. It is likely still made with the 7nm process. According to reports earlier this week, before the release of A13, we are likely to see another chip, the A12X, produced by TSMC for Apple, which may appear in the upcoming iPad Pro update model.
