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.

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.

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.

There is considerable speculation about which lithography Apple will employ for its future iPhone series. Previous reports have claimed that Apple will switch

TSMC to launch 2nm process in 2025. Taiwan Semiconductor Manufacturing Company (TSMC), the world's largest contract chipmaker, has announced plans to introduce its 2nm process in

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.

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