What is an NPU?
A Neural Processing Unit handles AI inference (image gen, speech, translation) more efficiently than CPU/GPU alone. Vendors quote performance in TOPS (trillion operations per second).
AI PC vs regular mini PC

Check NPU TOPS on product pages and the AI Performance Top ranking for NPU-equipped models.
Caveats
- TOPS alone does not guarantee the same real-world experience (drivers, software).
- You can still run AI on CPU/GPU without an NPU, usually with higher power draw.
