## Definition

Surface RTX Spark Dev Box is a compact developer workstation from Microsoft, powered by NVIDIA's RTX Spark superchip, designed to run 120-billion-parameter AI models locally without cloud costs. It delivers one petaflop of AI compute, 128 GB of unified LPDDR5X memory, and silent passive cooling inside an anodized aluminum chassis.

Announced at [Microsoft Build 2026 on June 2](https://blogs.windows.com/devices/2026/06/02/building-the-next-generation-of-devices-for-developers-surface-rtx-spark-dev-box/) alongside the Surface Laptop Ultra, the Dev Box ships developer-optimized Windows 11 Pro pre-loaded with VS Code, GitHub Copilot, WSL 2 with CUDA passthrough, and the full Windows Copilot Runtime. Pavan Davuluri, head of Surface, framed it as "a new category of Surface, built for developers."

## Analogy

Think of it as a Mac Pro for AI builders, minus the cloud invoice.

## Why it's emerging now

At Build 2026 on June 2, Microsoft and NVIDIA jointly announced a new tier of PC: RTX Spark-class local AI compute. The Surface RTX Spark Dev Box is Microsoft's first hardware in that tier — purpose-built to run frontier-scale models without a cloud subscription, directly challenging per-token API economics for developers.
