Microsoft prices RTX Spark Surface Laptop Ultra at $2,599 and Dev Box at $5,999

Microsoft puts prices and dates on its RTX Spark Surface hardware

Microsoft has revealed pricing and availability for the first Surface devices built on Nvidia's new Arm-based RTX Spark platform. According to The Verge, the Surface Laptop Ultra goes on sale October 16th with a starting price of $2,599, while the developer-oriented Surface RTX Spark Dev Box is available for preorder now at $5,999 and ships in November. Both announcements landed on October 7th.

Surface Laptop Ultra starts at $2,599

The base configuration of the Surface Laptop Ultra, which The Verge describes as Microsoft's most powerful Surface yet, pairs an 18-core CPU with 24GB of RAM and 512GB of storage. At the top of the range sits a $5,899.99 variant with 128GB of RAM, a 20-core CPU and 1TB of storage. Preorders opened on the day of the announcement.

The 15-inch HDR touchscreen can reach 2,000 nits of peak brightness, and the laptop features an enlarged trackpad with haptic feedback. Its aluminum body and premium positioning invite comparisons with the MacBook Pro, and The Verge notes that Apple's flagship is the machine Microsoft is going after. Port selection is relatively generous: three USB-C ports, one USB-A, HDMI, a full-size SD card reader and a 3.5mm headphone jack, plus a magnetic USB-C charging connector.

RTX Spark is an Arm-based processor that scales to 128GB of unified memory, and both Microsoft and Nvidia are placing these machines at the very top of the laptop market, targeting high performance in creative software, gaming and local AI workloads.

The $5,999 Dev Box targets local AI development

Where the Laptop Ultra is a general-purpose premium machine, the Dev Box is squarely aimed at developers. It runs the same Arm-based RTX Spark platform with the full 128GB of unified memory, and The Verge reports it is tuned for local AI work, including large models with more than 120 billion parameters — suited to testing AI models, prototyping AI agents or running AI coding tools entirely on the device.

The hardware itself is unconventional. Its flat, 3D-printed anodized aluminum chassis doubles as a heatsink, with venting that calls to mind the top of an Xbox Series X. The Verge also points to a 100-watt thermal envelope and Nvidia's Tensor cores, suggesting it would likely deliver strong gaming performance even though that is not its intended role.

The Dev Box belongs to Microsoft's Project Zenith line, so it ships with a developer-optimized Windows 11 Pro setup and a set of preinstalled tools: Visual Studio Code, Git, GitHub CLI, GitHub Copilot, WSL, Python and Node.

At $5,999, the Dev Box costs more than the DGX Spark mini PC Nvidia launched last year. The Verge attributes the higher price partly to climbing PC costs driven by shortages of RAM and other components.

Why it matters

Microsoft is staking out the top of an emerging category: Windows machines designed around big unified-memory Arm silicon, where local AI development is the headline use case rather than an afterthought. A $2,599 entry point and a near-$6,000 developer box place this hardware well beyond mainstream budgets, but they give developers a supported, preconfigured route to running very large models on-device — work that until recently demanded workstation-class rigs or cloud GPUs. The October 16th laptop launch sets up a direct premium-laptop confrontation with Apple's MacBook Pro, while the November Dev Box release, with its preinstalled toolchain, signals that Microsoft wants to own the developer environment for on-device AI, not just sell the silicon underneath it.
