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.

Apple's A16 chips are now being manufactured on American soil at TSMC's Arizona plant, according to Taiwan-based independent journalist

TSMC has started production in its first US fabrication unit in Arizona. It's manufacturing Apple's A16 processors.

Apple introduced its A16 Bionic processor in September 2022, along with its iPhone 14 Pro. Nowadays, this SoC is used for the iPhone 15 and iPhone 15 Plus, as the iPhone 14 Pro has been discontinued.

The TSMC Arizona factory has started producing Apple's A16 Bionic chips, which are the processors in the iPhone 14 Pro and 15.

TSMC has reportedly started production of Apple's iPhone chips in its Arizona foundry, with the first to be made in America set to be the A16.

Apple's A16 chips are now being fabricated at TSMC's Arizona facility. The A16 chip are reportedly being produced in small quantities.

A tweet by supply chain analyst Ming-Chi Kuo claims to shed light on Apple’s plans for the adoption of smaller process chips … His expectation is that all four iPhone 17 models will stick to 3nm chips next year,

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.
