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.

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

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.

Phone 17 lineup will be powered by processors fabricated using TSMC's enhanced N3P 3-nanometer chip technology.
