Microsoft and NVIDIA unveil Surface Laptop Ultra with RTX Spark for local AI agents and up to 128GB unified memory

What changed

Microsoft and NVIDIA unveiled Surface Laptop Ultra at a San Francisco event on October 7, positioning the machine for local AI agents, coding and creative workloads on Windows. Microsoft's product page says a new NVIDIA chip combines CPU and RTX GPU capabilities, delivering up to roughly one petaflop of AI compute and supporting up to 128GB of unified memory. The device remains a pre-release product subject to regulatory approval, so final configuration, pricing and shipment details may change. Reuters frames it as part of Microsoft's effort to shift some AI workloads from Azure to high-performance PCs.
