Every year, Apple has a new chip ready for its latest iPhones. But the A20 Pro chip for this fall’s iPhone 18 Pro and iPhone Ultra sounds like it could be extra special. Here are its two big rumored upgrades.
You can always bet on Apple to offer improvements in its latest generation chips. But some years bring bigger upgrades than others, and the new A20 Pro chip is expected to be a standout.
That’s because with A20 Pro, Apple will use TSMC’s new 2-nanometer process for chip fabrication.
The switch to 2nm from the current 3nm process means A20 Pro will be able to offer more power and run more efficiently within a similar-sized chip footprint.
Every time there’s a notable evolution of fabrication technology, we see this play out. That’s why Apple works years in advance to secure TSMC’s most cutting-edge offerings. It helps the company maintain an edge in the chips that power not only iPhone, but also, iPad, Mac, and more.
We don’t know which specific areas Apple will focus on improving with A20 Pro, but thanks to 2nm the company will have more headroom than usual.
Adding to the gains of 2nm, A20 Pro is also expected to have another unique improvement thanks to a packaging innovation called Wafer-Level Multi-Chip Module.
Here’s my colleague Marcus with the details:
For the first time, Apple is set to adopt Wafer-Level Multi-Chip Module (WMCM) packaging for its iPhone processors. WMCM allows different components, like the SoC and DRAM, to be integrated directly at the wafer level, before being diced into individual chips.
It uses a technique that connects the dies without needing an interposer or substrate, which can bring both thermal and signal integrity benefits.
In other words, Apple’s next-gen chip won’t just be smaller and more power-efficient thanks to N2. It’ll also be physically closer to its onboard memory, enabling better performance and potentially lower power consumption for tasks like AI processing and high-end gaming.
With WMCM, A20 Pro is expected to be especially capable at AI tasks. Which is no surprise, since iOS 27’s rumored headlining features seem entirely AI-centric.
What areas of improvement are you most hoping for in iPhone 18 Pro? Let us know in the comments.
