NPU

An NPU, or neural processing unit, is a specialized processor built to handle the matrix math of neural networks quickly and with little power. It sits alongside the CPU and GPU in phone and PC chips and is used to run AI models on the device.

Unlike a CPU, which handles general-purpose work, or a GPU, which is built for graphics and parallel computing, an NPU is tuned for AI inference, which helps on-device AI features run while saving battery.
