Lenovo has taken the wraps off the Lenovo AI Stick at MWC 2025 in Barcelona. The idea behind the product is right there in the name, and this time, the 'AI' isn't gratuitous. This USB-C Thunderbolt connected stick conceals a 32 TOPS NPU to enable those local AI-accelerated goodies Microsoft and its PC making partners are trying to convince you are the best thing since sliced bread. However, Lenovo's thumb-stick-sized device is flagged as a "proof of concept" for now.
Perhaps because the Lenovo AI Stick is a concept, we don't have many tech specs for the product. All we know from the specifications point of view is that the concept device includes an NPU that can deliver 32 TOPS. It also connects to the PC "via a USB-C Thunderbolt port," according to the official PR from Lenovo. Lastly, Lenovo suggests that the NPU will run faster if the AI Stick is powered with its adapter (connector on the side), which makes us wonder about USB-C-powered performance and the power requirements of this device.
