Every new laptop lists an NPU now. Here is what it does, and when a GPU still wins.

A neural processing unit runs AI math on a few watts, so AI features work all day on battery.

A graphics chip runs thousands of tasks at once. Almost every big AI model was trained on GPUs.

Copilot+ PCs need a 40 TOPS NPU. Snapdragon X2 Elite reaches 80. Ignore inflated "platform" totals.

Video call blur, live captions with translation, Windows Recall and smart search run on the NPU.

Offline chatbots, image generators like Flux, AI video and model training still need a strong GPU.

An RTX 5090 laptop GPU has 24 GB of fast memory. Most NPUs work best with small AI models.
