Microsoft and NVIDIA Unveil Surface RTX Spark AI Supercomputer for Developers

Microsoft Corp. today announced the Surface RTX Spark Dev Box, a desktop supercomputer developed with NVIDIA's new RTX Spark processor. It delivers up to 1 petaflop of AI compute, 128GB of unified memory, and can run 120 billion-parameter models using 4-bit quantization.

The Windows box runs Microsoft's Linux virtualization WSL 2 with native GPU passthrough, full CUDA support, and preinstalled tools including Visual Studio Code and GitHub Copilot. Availability is planned for later this year in the United States.

Alongside hardware, Microsoft introduced Windows Execution Containers (MXC), now in preview, allowing developers to create sandboxed environments for AI agents. MXC is also used by OpenClaw on Windows for autonomous agentic actions.

Developers can now use the GitHub Copilot app on desktop, orchestrating multiple agents in parallel using git worktrees. For scientists, Microsoft's Discovery platform is generally available, automating research workflows on Azure. Early adopters include BHP Group, Syensqo, and GlaxoSmithKline.
