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.

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,

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

The processors for 2025 iPhone 17 models will be made by TSMC’s N3P process/3-nanometer technology. The processor for 2026 iPhone 18 models is anticipated to use TSMC’s 2-nanometer technology. However, due to cost concerns, not all new iPhone 18 models may be equipped with a 2-nanometer processor.

According to Ming-Chi Kuo, the iPhone 17 may feature TSMC's enhanced N3P 3-nanometer chip tech. 2026's iPhone 18 Pro models may support the new 2nm processor.

TSMC might need help in packaging the chips. Apple is expected to introduce 2 nm chips next year, right in time for the iPhone 17 lineup. Latest

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.
