Microsoft launches $5,999 Surface RTX Spark Dev Box for AI developers
Microsoft’s high‑end AI mini‑PC, the Surface RTX Spark Dev Box, is now available to order and will start shipping in November.

Surface RTX Spark Dev Box opens pre‑orders at $5,999
Microsoft announced that the Surface RTX Spark Dev Box is now available for pre‑order directly from the company. The price tag sits at $5,999, positioning it as a premium, purpose‑built machine for developers working on artificial‑intelligence projects.
When it will arrive
The company said the first units are scheduled to ship in November 2026. No specific release date was given, but Microsoft confirmed that the box will be dispatched to customers after the pre‑order window closes.
What’s inside the chassis
The Dev Box is housed in a flat, 3D‑printed anodised aluminium case that doubles as a heatsink. Its design mirrors the vent layout of an Xbox Series X, giving it a distinctive, industrial look. Under the hood it runs Nvidia’s arm‑based RTX Spark platform and comes with 128 GB of unified memory. Microsoft highlighted a 100‑watt thermal envelope and Nvidia Tensor cores as the core of its performance.
AI‑focused capabilities
According to Microsoft, the machine is optimised for “local AI” workloads, including models that exceed 120 billion parameters. The idea is to let developers test large language models, prototype AI agents or run on‑device AI coding assistants without relying on cloud resources.
Software stack out of the box
The Dev Box ships as part of Microsoft’s Project Zenith initiative and arrives with a developer‑optimised Windows 11 Pro installation. Pre‑installed tools include Visual Studio Code, Git, GitHub CLI, GitHub Copilot, the Windows Subsystem for Linux, Python and Node. Microsoft says the bundle is intended to let developers start building immediately.
Who should consider buying it
While the hardware could double as a high‑end gaming rig, Microsoft positions the box squarely for developers. The price point is notably higher than Nvidia’s DGX Spark mini PC, but the company argues the integrated software and Windows environment justify the premium.
Related hardware
The launch coincides with the unveiling of the Surface Laptop Ultra, another device aimed at power users. Both products showcase Microsoft’s push to bring more AI‑centric hardware to the consumer market.
What comes next
Microsoft has not disclosed how many units will be produced or whether there will be a later, lower‑cost version. Interested developers can place orders now through Microsoft’s online store, with shipping expected in November.
