At the Windows and Surface Event 2026 on Wednesday, Microsoft and NVIDIA unveiled the Surface Laptop Ultra, a premium device powered by the NVIDIA RTX Spark superchip, marking a significant push into local AI and high-performance computing. Also announced, are the general availability of Microsoft Execution Containers (MXC) for AI agent governance; a new ecosystem of RTX Spark PCs from major partners, alongside updates to Windows Hybrid Intelligence for Copilot.
The centerpiece, the Surface Laptop Ultra, is Microsoft’s most powerful Surface laptop, featuring a 15-inch PixelSense Ultra display and an NVIDIA RTX Spark platform that combines a Blackwell RTX GPU and Grace CPU with up to 128 GB of unified memory.
Priced starting at $2,599 (base configuration with 24 GB RAM) and up to $5,899 (top tier with 128 GB RAM and 1 TB storage), Surface Laptop Ultra offers up to 1 petaflop of FP4 AI performance and can run local AI models exceeding 120 billion parameters. It ships on October 16, 2026, alongside a compact desktop alternative, the Surface RTX Spark Dev Box which is priced at $5,999 and ships in November.
Beyond Microsoft’s own hardware, the RTX Spark platform expands to a broader ecosystem of Windows PCs from partners including Lenovo, Asus, Dell, HP, MSI, and Gigabyte. These devices, ranging from laptops to compact desktops, are designed to deliver high-end AI and graphics performance, with many already available for pre-order.
On the software side, Microsoft detailed its vision for Windows Hybrid Intelligence, enhancing Copilot with deeper local capabilities. This integration allows Copilot to seamlessly switch between local on-device models and cloud-based models, improving privacy and reducing latency for everyday tasks.
To support the growing use of AI agents, Microsoft announced the general availability of Microsoft Execution Containers (MXC), a technology that isolates and governs AI agents across Windows, macOS, and Linux environments, ensuring secure and controlled access to system resources. The tech giant also showcased partnerships for local AI integration, including Meta’s Muse personal agent coming to Windows.
