alt Hacker News> Another incredible aspect is the early addition of an NPU by Apple in a SoC.
I'm going to go out on a limb and guess that you've not used CUDA yet. NPUs are a lot of things, but "incredible" is the last word an engineer would use to describe them these days.
Incredible means they follow a SoC approach where the RAM is shared between CPU, GPU, and NPU instead of separated like in a typical GPU such as Nvidia.
