A20 Pro chip specs leak: 2nm process, doubled Neural Engine compute
Leaker account testingcatalog and blogger Linus Ekenstam leaked specs of Apple's next-gen A20 Pro chip on September 10, with consistent core details: doubled Neural Engine compute, doubling down on on-device local AI model execution. None of this has been confirmed by Apple officially.
Confirmed
- All of the above is leak material with no official Apple response; "confirmed" here only means points corroborated across the leaks.
- testingcatalog claims the A20 Pro delivers roughly 40% overall performance improvement over the iPhone 17 Pro, with doubled Neural Engine compute for running AI models locally on device; the chip has a 6-core CPU and 7-core GPU.
- Linus Ekenstam's summary is more specific: the A20 Pro uses a 2nm process, a 6-core CPU with 2 performance cores + 4 efficiency cores, a 7-core GPU, a 32-core Neural Engine (doubled compute), an FP8 neural accelerator that is twice as fast, 50% higher memory bandwidth, and roughly 70% of related thermal improvements (original post truncated).
- The chip is expected to ship in the iPhone 18 Pro/Pro Max.
- testingcatalog previously also revealed that Siri AI will launch in Beta in October.
Unconfirmed
- All specs (2nm process, core configurations, compute uplift, 40% overall performance gain) come from leaks and are unconfirmed by Apple.
- The claim of an October Siri AI beta is likewise unconfirmed.
Why it matters
- The doubled Neural Engine compute and FP8 acceleration show Apple continues to push on-device AI horsepower, another signal of the trend toward local LLMs on phones; if the 2nm process holds true, it would also be a major milestone for mobile chip fabrication.
