AI PCs Explained: What Does an NPU Actually Do?

Modern laptops increasingly include NPUs. Here is what that hardware is designed to do.

The term AI PC is appearing across laptop marketing, and one of the key pieces of hardware behind it is the NPU, or neural processing unit.

What is an NPU?

An NPU is a processor designed to handle certain machine-learning workloads efficiently.

Instead of sending every AI-related task to the CPU or GPU, compatible software can use the NPU for specialized processing.

Why efficiency matters

Some AI features run continuously in the background, such as camera effects, transcription or image processing.

An NPU can handle suitable workloads using less power than relying on a high-performance GPU for everything.

Not every AI feature uses the NPU

Software support matters. Applications have to be designed to take advantage of the hardware.

Some AI services still run primarily in the cloud rather than locally on the laptop.

Should it affect your buying decision?

If you plan to keep a laptop for several years, newer hardware with an NPU may provide better support for future local AI features.

But memory, storage, battery life, display quality and overall performance remain important buying factors.
