Reverse-Engineering Apple Neural Engine Architecture on M1
September 12, 2026
An analysis of the M1 Apple Neural Engine reveals an overly opinionated architecture that limits general-purpose acceleration. The findings suggest a shift in hardware design, as newer M5 chips integrate NPU cores directly into the GPU to improve LLM performance.
