The iPhone 16 family of phones all use a chip called A18, which is made by TSMC. Both chips are made on a second-generation 3nm process, and appear to be the same aside from a binned version used in the non-Pro phones.

Next year's iPhone 17 series will feature processors made using TSMC's enhanced N3P 3-nanometer chip technology, but only iPhone 18

A new report from analyst Ming-Chi Kuo says that only certain models of the 2026 iPhone 18 range — presumably the Pro editions — will get 2nm processors.

After its glorious launch event on September 9, the iPhone 16 series has finally started hitting the shelves. Still, the rumor mill is already buzzing with not only iPhone 17 leaks but also iPhone 18,

If Apple continues its recent strategy of reserving the most advanced chips for the Pro models, then the 2nm chips would be exclusive to the iPhone 17 Pro and Pro Max. The will likely mean the expected ultra-thin model that has been dubbed the iPhone 17 Air would not get the chip.
