I do not see any mention of an "AI engine" (HN title) in the article.

> A hardware unit built into the company's Ryzen 7040-series APUs ... XDNA AI engine is an on-die accelerator designed for lower-intensity AI inference workloads, such as audio, photo, and video processing. It aims to deliver faster response times than online services and is more power-efficient than CPU or GPU-based solutions. The engine can handle up to 4 concurrent AI streams and processes INT8 and bfloat16 instructions. AMD claims this engine is faster than Apple's M2 processor’s neural engine.
