Your next iPhone might think quicker and last longer. Apple is changing how it builds chips for its 2026 iPhones, including the Pro models and the rumored foldable device.

For the first time ever, Apple’s A20 chip – made using TSMC’s newest 2nm technology – will use a special packaging method called Wafer-Level Multi-Chip Module (WMCM). Here’s the simple version: Instead of putting the main brain (SoC) and the short-term memory (DRAM) on separate pieces and connecting them later, Apple will stick them together before slicing the silicon wafer into individual chips.

This tighter packing means signals travel shorter distances between the processor and memory. The result? Phones get faster, especially for heavy tasks like AI or gaming, while potentially sipping less battery. It also helps manage heat better. Think of it like moving roommates into the same apartment instead of separate buildings – everything communicates faster.

Behind the scenes, chipmaker TSMC is reportedly setting up a whole new production line just for this WMCM tech. They aim to produce 50,000 units monthly by late 2026, scaling up to over 110,000 by end of 2027.

This move follows Apple’s pattern of jumping early on advanced chip tech, like it did with 3nm. It also shows that smartphone chips are starting to borrow tricks once only seen in powerful data center computers.

Interestingly, the long-rumored iPhone Fold might be more than just a new shape – it could serve as Apple’s testbed for this cutting-edge packaging before it spreads to other devices.

The A20 chip is expected to power the iPhone 18 Pro, Pro Max, and the potential foldable model when they launch in late 2026.
