Build 2026: Nvidia-Powered Surface RTX Spark Dev Box is Coming Later this Year

The new Surface Laptop Ultra that Microsoft announced yesterday won’t be the only Surface device powered by Nvidia’s new RTX Spark Chip. At its Build 2026 conference this morning, Microsoft announced the Surface RTX Spark Dev Box, a new workstation that will offer the same one petaflop of AI compute and 128 GB of unified memory to developers later this year.

Nvidia’s new ARM-based chip will be ideal for running AI workflows locally, and the new workstation will support the full NVIDIA AI stack. The RTX Spark chip has enough compute power to run 120B+ parameter models with 1 million token context locally. It will also ship with a new developer configuration for Windows 11, with local sandboxing for agents, new Windows Subsystem for Linux capabilities, and more.

“Surface RTX Spark Dev Box ships with a developer-optimized Windows 11 experience – preconfigured with all your essential developer tools – Visual Studio Code, GitHub Copilot available inline in Windows Terminal, WSL, PowerShell 7 and Windows settings tuned for development – so you spend less time configuring your machine and more time building from the moment you sign in,” said Pavan Davuluri, Executive Vice President, Windows + Devices.

The Surface RTX Spark Dev Box will launch later this year in the US, and it will be available exclusively via Microsoft.com. Just like the Surface Laptop Ultra, pricing details aren’t available yet. Microsoft said that the new developer device has yet to receive FCC clearance.
