At a joint event in San Francisco on October 7, NVIDIA CEO Jensen Huang and Microsoft CEO Satya Nadella announced RTX Spark — a platform that brings the full NVIDIA AI software stack to Windows laptops and compact desktops. Preorders opened immediately, with laptops shipping October 16 and compact desktops arriving in November. Systems will be available from Acer, ASUS, Dell, HP, Lenovo, Microsoft, MSI, and Gigabyte.
RTX Spark combines an NVIDIA Blackwell RTX GPU with up to 6,144 cores and an up to 20-core NVIDIA Grace CPU connected at 600 GB/s. The platform delivers one petaflop of FP4 AI performance and up to 128 GB of unified memory — enough to run frontier-class models like Qwen 3.8 Flash Next (125B parameters, 51B active) entirely locally, without sending data to the cloud. Microsoft’s new Surface Laptop Ultra is built around the RTX Spark architecture, offering up to 128 GB of unified memory and petaflop-class compute in a laptop form factor.
Microsoft also announced the general availability of Microsoft Execution Containers (MXC) — OS-level infrastructure that lets AI agents run safely and persistently in the background under Windows control. “With MXC, Microsoft Security, and Agent 365, we’re unlocking the full potential of agents on Windows,” said Pavan Davuluri, Microsoft’s EVP of Windows and Devices. NVIDIA also previewed DGX Station for Windows — the first deskside AI supercomputer for the Windows enterprise desktop, running on the GB300 Grace Blackwell Ultra Desktop Superchip with 748 GB of coherent memory and up to 20 petaFLOPS of FP4 compute.
