Microsoft, Nvidia launch RTX Spark Windows AI PC lineup

FutureFive New Zealand reports that Microsoft and Nvidia have unveiled a new line of Windows PCs built on the Nvidia RTX Spark platform, spanning laptops and small-form-factor desktops. The rollout begins with devices from Surface, Asus, Dell, HP, Lenovo, and MSI, as Microsoft pushes Windows on Arm into higher-end systems for developers, creators, and gamers.

At the centre of the announcement is RTX Spark, delivering up to 1 petaflop of AI performance, up to 20 Arm-based CPU cores, up to 6,144 Blackwell RTX cores, and as much as 128GB of unified memory. Microsoft has tuned Windows to work closely with the heterogeneous design through workload profile scheduling, power management improvements, and enhanced unified memory support that allows larger local AI models and more demanding creative workloads to run on these machines.

Microsoft also highlighted the Copilot+ PC positioning of the new systems, pairing dedicated AI processing on NPUs with the GPU's graphics and AI capabilities. The company emphasized that Windows is being adapted to build and run AI agents securely on-device through operating system-level identity, containment, and management features. The announcement also extended to Nvidia DGX Station for Windows, based on the GB300 Grace Blackwell Ultra Desktop Superchip, bringing workstation-class AI development to deskside Windows systems.
