Nvidia's RTX Spark laptops launch, built to run AI agents locally
Nvidia's RTX Spark laptops are now on sale from ASUS, Dell, HP, Lenovo, Microsoft and MSI, pitched by Nvidia and Microsoft as a new class of Windows PC for running AI agents on the device itself. Each machine pairs an Arm-based Grace CPU with a Blackwell RTX GPU on a single superchip, with up to 128GB of unified memory and up to 1 petaflop of FP4 AI compute; MediaTek worked on the processor design. Windows adds a first-boot experience that can install supported agents such as Hermes, Perplexity and OpenClaw in two clicks, while Nvidia released the open-weight Nemotron 3.5 Bolt (74B parameters, 9B active, fits in 24GB), a Switchyard router for splitting work between local and cloud models, and an OpenShell runtime for controlling agent behavior. The Verge's hands-on found OpenClaw needed an uninstall and reinstall to work, and Copilot Plus features such as Recall are unavailable at launch.
If local agents prove usable, the pitch for Windows PCs shifts from raw benchmarks to which agents they can run and whether data stays on the device.
