A dedicated machine-learning processor built into Apple silicon chips, used to accelerate on-device AI tasks like image recognition and Siri features.
Apple doubled the Neural Engine in the A20 Pro. In the one head-to-head Mashable ran, the new Pro Max and last year's model produced the same image in exactly the same time. That leaves battery and cooling as the upgrade case.

Apple's Kids Category rule and COPPA's definition of a child's voice both point a preschool voice product at local processing, and Whisper's error on children's speech falls by nearly a factor of three from tiny to large-v3.

iOS 27 shipped Monday with a Siri built by distilling Gemini's answers into Apple's own on-device models, gated behind an English-only waitlist and unavailable in the EU and China. Paid cloud limits come later.

The M6 reached TSMC's N2 process before the A20 Pro did, pinning down what the iPhone 18 Pro's chip is built on. Its memory bandwidth number tells on-device AI teams how much room next year's phone actually adds.

The published deltas put the Neural Engine at 2x and multithreaded CPU at 1.2x. Apple's own workload figures widen that gap further, and the lineup stops at base tier.

A mobile engineer says LangFuse and LangSmith could not show him why models misbehaved on real handsets, so he is building a flight recorder around thermal state and memory pressure.

The EdgeFirst Model Zoo ties every published result to the artifact, dataset and host that produced it. The arithmetic underneath is the actual argument against buying on peak throughput.
