Apple's A20 Pro chip delivers 40% faster graphics, 2x AI compute in iPhone 18 Pro
Apple unveiled the A20 Pro, its first 2nm smartphone chip, powering the iPhone 18 Pro and the new foldable iPhone Duo. The chip promises up to 40% faster graphics and double the AI compute of its predecessor, with a redesigned thermal system for sustained performance. The iPhone 18 Pro starts at €1,103 ($1,199), the Duo at €1,839 ($1,999).
Bottom line — The A20 Pro's 2nm process and doubled AI compute set a new benchmark for on-device intelligence in smartphones.

- The A20 Pro uses TSMC's 2nm N2 process with gate-all-around transistors, per Gadget Review, offering 10–15% performance uplift at equal power or 25–30% lower power at equal performance.
- Apple claims the 6-core CPU is up to 20% faster than the A19 Pro, calling it 'the fastest CPU in a smartphone,' per MacRumors.
- The 7-core GPU delivers up to 40% faster graphics and includes new neural accelerators for twice the FP8 compute, according to Tom's Hardware.
- A dual 16-core Neural Engine provides 2x the compute of the previous generation and supports 8-bit floating point math for local AI models, Apple said.
- Apple redesigned the chip packaging to connect silicon directly to a vapor chamber, improving thermal management; the iPhone 18 Pro claims 40% more sustained performance over the A19 Pro, per MacRumors.
- The iPhone Duo foldable features a 7.6-inch (19.3 cm) inner display with nano-texture finish and a 5.4-inch (13.7 cm) outer display, per Apple Newsroom.
- The Duo uses Touch ID instead of Face ID, has a dual-battery system, and claims up to 31 hours of video playback on the inner display, according to Apple.
- The iPhone 18 Pro introduces a 48MP main camera with variable aperture (f/1.48), a first for iPhone, per Notebookcheck.
- Both phones include Apple's C2 cellular modem, replacing Qualcomm, with mmWave support in the US and 15% lower energy consumption, per Tom's Hardware.
- Pre-orders for the iPhone 18 Pro start September 12 with availability September 18; the Duo pre-orders begin October 16 with availability October 23, per Apple.
