Recent leaks and rumors have suggested that Apple's upcoming iPhone 18 Pro, expected in late 2026, may feature a new A20 chip built on a 2-nanometer (nm) manufacturing process. This would represent a significant advancement from the current 3nm technology used in the A17 and A18 chips.
According to industry analysts and supply chain reports, TSMC, Apple's primary chip manufacturer, is on track to begin mass production of 2nm chips in the second half of 2025 or early 2026. However, as of May 2026, Apple has not officially confirmed any details about the A20 chip or the iPhone 18 Pro.
The rumored 2nm design could bring major performance and efficiency improvements, potentially offering up to 10-15% faster speeds and 25-30% lower power consumption compared to 3nm chips, based on TSMC's stated goals. Upgraded packaging, such as a new system-in-package (SiP) design, may also be included to improve thermal management and enable new features.
It is important to note that these details are based on unverified leaks and industry speculation. Apple typically does not comment on future products, and the final specifications of the iPhone 18 Pro may differ from current rumors.
