Microsoft is working on its most powerful developer system, powered by NVIDIA, the Surface RTX Spark Dev Box.
Microsoft Goes All-In on NVIDIA With RTX Spark-Powered Surface RTX Spark Dev Box
At Build 2026, Microsoft is announcing its Surface RTX Spark Dev Box, which is built on the same foundation as its recently announced Surface Laptop Ultra. The machine harnesses the power of NVIDIA's RTX Spark SoC, which was announced a few days ago, bringing significant AI performance to developers locally.
The difference between Microsoft's RTX Spark Dev box and other RTX Spark systems is that the developer system will ship with a developer-optimized Windows 11 operating system, allowing devs full control of AI deployments with minimal setup time. Some of these features include Visual Studio Code, GitHub Copilot in Windows Terminal, WSL, and PowerShell 7.
And performance is superb, with the NVIDIA RTX Spark SoC offering 1 PFLOPs of AI compute, along with 128 GB of fast LPDDR5X memory. As we already know, the SoC ships with 20 Arm CPU cores, the same as the DGX Spark, and an NVIDIA Blackwell GPU with 6144 CUDA cores, all combined in the GB10 or N1X chip.
Surface Dev Box with RTX Spark can run 120B+ parameter AI models with 1 million token context. With its 128 GB of unified memory, of which 112 GB can be dedicated to the GPU, you are going to run AI locally & speedily. Besides that, the system is backed by a powerful AI stack, which includes WindowsML with TensorRT, Windows Copilot Runtime, and Tooklit for VS Code that allows model conversion, fine-tuning, and evaluation. Security features include:
- Secured-core PC architecture
- BitLocker encryption
- Microsoft Defender protection
Microsoft will be shipping the Surface RTX Spark Dev Box in a premium chassis that utilizes anodized aluminum 3D printed body with 1000 air vents built into the grid chassis design. You can say that each vent is dissipating 1 TeraFlops of compute power. The chassis is designed to sustain up to a 100W TDP, and with its aluminum materials, you get a fully passive-cooled design that is performant and runs at zero noise.
For IO, the Microsoft Surface RTX Spark Dev Box features two USB Type-C ports, a USB-A port, an HDMI port, Ethernet LAN, and a headphone jack. The system is expected to launch later this year in the US through the official Microsoft store. Pricing will be set slightly higher than the Surface Laptop Ultra.
