A20 Pro revealed: 2nm process, doubled Neural Engine cores
Apple's next-gen A20 Pro chip was revealed in detail on September 10, combining an on-stage disclosure by MKBHD at the Apple event with corroborating leaks from testingcatalog, Linus Ekenstam, and Reddit users, all painting the same picture: a major upgrade built around on-device AI compute.
Confirmed
- Per MKBHD at the event (relayed in m2): 2nm process, 6-core CPU, 7-core GPU, Neural Engine doubled to 32 cores, 50% higher memory bandwidth, with the doubled Neural Engine aimed at on-device model inference.
- @eyishazyer adds structural detail: the 32-core Neural Engine is split into two 16-core modules with double the AI compute of the A19 Pro; the A20 Pro is claimed to be the first high-volume smartphone chip on TSMC's 2nm process, a claim the author verified across three media reports.
- Linus Ekenstam's summary: the 6-core CPU pairs 2 performance and 4 efficiency cores; the FP8 neural accelerator is twice as fast; thermal improvements of roughly 70%.
- A Reddit user adds memory specifics: a 96-bit LPDDR5X bus (up from 64-bit) delivering about 115 GB/s, up 50%, consistent with Ekenstam.
- testingcatalog reports 40% overall performance gains over the iPhone 17 Pro, with the chip landing in the iPhone 18 Pro/Pro Max; the foldable iPhone Duo will also use the A20 Pro, marketed as delivering peak performance for on-device AI models, alongside a C2 chip with 50% faster uploads and quicker network reconnection, and a livestream claiming 24-hour battery life.
- testingcatalog previously said Siri AI will launch in beta in October.
Unconfirmed
- Beyond the on-stage specs, the 40% gain, 96-bit bus and 115 GB/s bandwidth, thermal details, iPhone Duo battery and C2 chip claims remain leak-sourced without itemized official confirmation.
- The October Siri AI beta has not been officially confirmed.
Why it matters
- Doubled Neural Engine compute, FP8 acceleration, and much wider memory bandwidth signal Apple's continued push into on-device AI for local models.
- If the TSMC 2nm high-volume claim holds, the A20 Pro marks a major mobile process milestone.
- The iPhone Duo leaks tie the A20 Pro to a foldable form factor for the first time, suggesting on-device AI as the foldable's headline selling point.
