RTX Spark and MXC on Windows
- October 8 confirmed that RTX Spark laptops, including Microsoft's $2,599 Surface Laptop Ultra, ship October 16, with compact OEM desktops, a lineup now including Gigabyte, following in November.
- Ars Technica confirmed dual Blackwell GPU options (5120-core and 6144-core) with LPDDR5x unified memory, and noted that unified memory extends to AAA gaming, with Gears of War: E-Day demonstrated on the device.
- Jensen Huang and Satya Nadella announced RTX Spark at a San Francisco event alongside MXC, Microsoft's OS-level agent sandboxing framework now generally available on Windows 11.
RTX Spark brings petaflop-scale AI compute and up to 128GB unified memory to consumer laptops and compact desktops, enabling local inference of large models without cloud dependency. MXC's general availability gives enterprises an OS-enforced security layer for running AI agents directly on Windows devices.
