NVIDIA RTX Spark and Microsoft MXC Containers Launch at Joint Windows AI Event
The gist
RTX Spark and DGX Station for Windows bring petaflop- and multi-petaflop-scale local AI inference to laptops and enterprise desktops without cloud dependence. MXC's general availability gives enterprises an OS-enforced security boundary for running AI agents directly on Windows devices.
The full picture
At a joint event in San Francisco, NVIDIA and Microsoft announced RTX Spark, a new chip combining a Blackwell RTX GPU with up to 6,144 cores and an up to 20-core Grace CPU, delivering one petaflop of FP4 AI performance and up to 128GB unified memory. RTX Spark laptops are available for preorder and ship October 16; compact desktops follow in November. Microsoft simultaneously announced general availability of Microsoft Execution Containers (MXC) on Windows 11, an OS-level sandboxing system that lets administrators define per-agent file and network access policies with Windows enforcing isolation. NVIDIA also previewed DGX Station for Windows, the first version of its deskside supercomputer to run on Windows rather than Linux only, powered by the GB300 Grace Blackwell Ultra Desktop Superchip with 748GB of coherent memory and up to 20 petaFLOPS of FP4 AI compute. Microsoft's Surface Laptop Ultra, built around RTX Spark, starts at $2,599; the Surface RTX Spark Dev Box starts at $5,999. OEM partners for RTX Spark devices include Acer, ASUS, Dell, HP, Lenovo, MSI, and Gigabyte.
