Apple’s upcoming A20 and A20 Pro chips, built on a new 2nm process, are set to make the iPhone 18 series the fastest and most efficient iPhones yet.
Key Takeaways
- Apple is developing A20 and A20 Pro chips for iPhone 18 models.
- The chips will use TSMC’s advanced 2nm manufacturing technology.
- iPhone 18 Pro and foldable models may launch in September 2026, with standard models following in March 2027.
Chip Strategy: A20 and A20 Pro
According to leaks from reliable source Mobile Phone Chip Expert on Weibo, Apple is preparing two versions of its next-generation processor. The standard iPhone 18 is expected to feature the A20 chip, while the A20 Pro will likely power the iPhone 18 Pro models and the rumoured foldable iPhone.
The report didn’t specify which chip would be used in the anticipated entry-level iPhone 18e or a potential second-generation iPhone Air.
2nm Technology Leap
The A20 series represents Apple’s transition to TSMC’s advanced 2nm process, moving from the 3nm technology used in current A17 Pro through A19 Pro chips. This manufacturing improvement is expected to deliver significant performance and energy efficiency gains.
Some rumours suggest certain A20 chips might feature RAM integrated directly onto the same wafer as the CPU, GPU, and Neural Engine. This integration could reduce chip size and further enhance efficiency compared to current designs where components are connected via a silicon interposer.
Staggered Launch Timeline
Apple is reportedly planning a staggered release schedule for the iPhone 18 series. The iPhone 18 Pro, iPhone 18 Pro Max, and foldable iPhone could launch in September 2026. It remains uncertain whether a second-generation iPhone Air will debut alongside these devices.
A subsequent launch in March 2027 may see the release of the iPhone 18e and standard iPhone 18. If this timeline holds, the A20 Pro would be unveiled in 2026, with the A20 following in 2027.
