Apple’s chip development roadmap has long dictated the performance trajectory of its flagship product lines, and if current industry reports hold, the iPhone 18 Pro line—and potentially Apple’s first folding iPhone—could mark a new era in mobile silicon.

The 2nm Transition: What’s Changing?

Multiple analyst reports, including recent commentary from Jeff Pu (GF Securities) and Ming-Chi Kuo (TF International Securities), point to Apple equipping the iPhone 18 Pro, Pro Max, and projected iPhone Fold with a newly designed A20 processor. The most discussed upgrade is the use of TSMC’s 2nm fabrication technology, representing a generational leap from the 3nm nodes used in current A-series chips.

Advancements in Fabrication

TSMC’s 2nm process is expected to enable higher transistor densities, leading to improvements in performance and efficiency. According to industry sources, the 2nm node could allow for:

• Increased processing performance with comparable or reduced power
