**What happened:** Apple unveiled the A20 Pro chip at its "Surprise and Shine" event on 9 September 2026, alongside the iPhone 18 Pro, iPhone 18 Pro Max and its first foldable phone, the iPhone Duo.

**The numbers:** The A20 Pro packs a 32-core Neural Engine, double the AI compute of its predecessor. Its six-core CPU includes two "supercores" that are 20% faster, plus four efficiency cores. The new 7-core GPU is up to 40% faster, with 2x FP8 performance and 50% more memory bandwidth. Overall sustained performance is 40% higher than the A19 Pro, and double the A18 Pro.

**The details:** The iPhone Duo starts at $1,999. iPhone 18 Pro prices rise $100. Apple also announced new smartwatches and AirPods 5. The standard iPhone 18 arrives in spring 2027.

**The context:** The A20 Pro is the first high-volume smartphone chip built on TSMC's 2-nanometre process. Apple has committed to making some iPhone chips at TSMC's Arizona facilities.

**Why it matters:** Apple is betting on AI that runs directly on the device rather than in the cloud as it works to catch up in the broader AI race. In July, Apple briefly overtook Nvidia as the world's most valuable company.

**In their words:** Apple called the A20 Pro "the ultimate chip for running advanced on-device models," adding it has "the widest memory interface we've ever shipped in an iPhone."

**Who's affected:** Buyers of the iPhone 18 Pro, iPhone 18 Pro Max and the new foldable iPhone Duo get the chip first; standard iPhone 18 buyers wait until spring 2027.

**What's next:** Apple's on-device AI push will be tested as developers build for the new Neural Engine and FP8 support, with the foldable iPhone Duo marking the company's first entry into that category.

## Key takeaways

- A20 Pro is first high-volume 2nm smartphone chip, made by TSMC.
- Powers iPhone 18 Pro, Pro Max and new foldable iPhone Duo, from $1,999.
- Neural Engine hits 32 cores, doubling AI compute over predecessor.
