Apple A20 to Use TSMC 2nm Process

Apple is reportedly gearing up for a major leap in mobile silicon with its A20 chip series, expected to debut in 2026. The lineup is set to use TSMC's advanced 2nm process and introduce a new chip packaging approach that moves away from today's InFO design toward wafer-level multi-chip modules. This shift is aimed squarely at boosting both performance and power efficiency, a change that could shape how future iPhones handle demanding tasks like AI, graphics, and multitasking.

According to reports, the new WMCM technology allows Apple to combine CPU, GPU, NPU, and other chiplets into a single package while still keeping them modular. This gives Apple more freedom to tune core counts and performance profiles across different models, instead of relying on a one-size-fits-all processor design. By letting each chiplet manage power on its own, the architecture is also expected to cut unnecessary energy use and deliver better efficiency under real-world workloads.

Manufacturing is being refined as well. TSMC's approach uses molded underfill materials that simplify production and reduce material waste, helping offset the higher costs that come with moving to 2nm fabrication. In theory, this should improve yields while keeping Apple's most advanced chips commercially viable.

The A20 series is also rumored to bring sizable cache upgrades. Standard models are expected to see larger L2 caches for both performance and efficiency cores, while the A20 Pro could take system-level cache into an entirely new range. Combined with higher memory bandwidth, these changes should translate into faster data access, smoother multitasking, and better responsiveness, especially for AI workloads and high-resolution graphics.

On the graphics side, Apple is said to be extending the performance gains from the A19 Pro and adding a third-generation version of its dynamic GPU caching system. This technology allocates memory in real time based on workload, helping demanding games and professional apps run more smoothly without wasting resources.

In terms of products, the A20 Pro is expected to power the iPhone 18 Pro and Pro Max, along with Apple's first foldable iPhone. The standard A20 may arrive later in a renamed base model, possibly in early 2027. Meanwhile, reports suggest the follow-up to the ultra-thin iPhone Air could face delays or even cancellation due to weaker-than-expected market response.
