It's believed that TSMC will supply 20nm A8 chips for the upcoming 6C model and 16nm FinFET chips for the 6S models. The company has reported record revenue for January 2015 likely due to its major role in supplying processors for the iPhone 6 and iPhone 6 Plus.
Apple is said to be targeting a price of $400-500 for the new iPhone 6C. That's lower than the current $549 price of the iPhone 5s.
Shipments of the iPhone 6C, which will launch as the entry-level product for the brand with a price tag between US$400-500, are expected to reach 10-20 million units in the first year after its release, the sources estimated.
While TSMC is said to be providing chips for the iPhone 6S and 6S Plus, Samsung is also identified as a supplier.
As usual, Apple is expected to unveil the new smartphones in September or October of this year. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
