The iPhone 18 Expected to Feature A20 ChipsEnhanced CPUs May Utilize an Advanced 2nm ProcessThis Transition Promises Enhanced Speed and Efficiency
Although the launch of the iPhone 18 series is still over a year away, projections regarding its specifications have already begun to surface. The latest insights indicate that all models within this series are anticipated to receive a significant boost in performance.
This prediction comes from renowned Apple analyst Ming-Chi Kuo, who has reiterated a forecast he made six months prior: the A20 chipsets that will power the iPhone 18 models are set to be manufactured with a 2-nanometer process.
Currently, the iPhone 16 lineup employs A18 processors that utilize 3nm technology. Transitioning from a 3nm to a 2nm process allows for a greater number of transistors to be incorporated into the chip, resulting in improvements in both speed and efficiency.
While annual enhancements in speed are a tradition for the iPhone series, a shift in manufacturing techniques such as this typically results in more pronounced performance improvements, promising the iPhone 18 elevated processing capabilities.
A Future Launch
Kuo has reiterated his earlier statement, forecasting that the new iPhones, including the iPhone 18, will incorporate TSMC’s 2nm chip technology in the latter half of 2026. Notably, TSMC has reported that its 2nm research and development trial yields have significantly improved, achieving between 60% to 70% three months ago and now exceeding that benchmark.

There is still some uncertainty regarding whether all iPhone 18 models will feature the 2nm upgrade. Kuo appears to have grown more optimistic about this prospect compared to his previous stance in September. However, it is possible that this advancement could be limited to the Pro and Pro Max variants.
This speculation aligns with earlier remarks made by another industry analyst, Jeff Pu from GF Securities. Initially, Pu posited that the A20 chip would rely on a 3nm design but later adjusted his assessment to acknowledge that a 2nm version could indeed be feasible.
It is likely that even Apple and its supply chain partners are still working out the details regarding the chip specifications. With the iPhone 18 set for a September 2026 release, there remains ample time to continue refining these manufacturing processes.
In the interim, tech enthusiasts can set their sights on the upcoming iPhone 17 series, expected to debut in September 2025. These models are set to include upgrades to A19 processors, but will still rely on the existing 3nm technology.
