Microsoft used its Wednesday event in San Francisco to introduce the Surface Laptop Ultra, its first Surface built around Nvidia’s RTX Spark platform. Preorders opened in selected markets, with the laptop starting at $2,599 and shipping reported for October 16. The broader pitch: run more AI work on Windows PCs, while keeping cloud processing available for tasks that need it.

Surface Laptop Ultra: price, availability and reported specs
Microsoft CEO Satya Nadella and Nvidia CEO Jensen Huang appeared at the event alongside Windows and Devices chief Pavan Davuluri.

7 Microsoft also announced RTX Spark PCs from Asus, Dell, HP, Lenovo and MSI, which it said were available for preorder in selected markets.
Reporting puts the Surface Laptop Ultra’s starting price at $2,599 and its shipping date at October 16. The reported entry configuration has an 18-core CPU, a 5,120-core Blackwell GPU, 24GB of unified memory and 512GB of storage.

Microsoft describes the laptop as a 15-inch device with a mini-LED display, weighing under 4.5 pounds and measuring under 18mm thick. The company also calls its magnetic USB-C charging connection the first built-in system of its kind in a laptop; that is Microsoft’s product claim.
2 Microsoft notes that the product is pre-release and that features may vary by region.
The strategy: local AI plus the cloud
Microsoft’s central message was not that cloud AI is going away. It was that some work—such as coding tasks—could run directly on a capable PC instead of relying on a remote data center for every step.
4 Nadella described this as “hybrid intelligence”: a mix of local and cloud computing, rather than a permanent choice between them.

That distinction matters. The event presented the Surface Laptop Ultra as one part of a wider effort to make Windows PCs suitable for AI workloads, not as a claim that every AI task can run locally. Microsoft and its partners also announced other RTX Spark-powered PCs, broadening the hardware lineup beyond Surface.
A separate machine for AI developers
Microsoft also introduced the Surface RTX Spark Dev Box, a developer-focused system with 128GB of unified memory and up to one petaflop of AI compute, according to Microsoft. Microsoft’s Build materials describe the Dev Box as capable of running local models with up to 120 billion parameters. That figure applies to the Dev Box—not necessarily to the Surface Laptop Ultra.
The distinction is useful when comparing the announcements: the Laptop Ultra is a premium Windows laptop for local AI and other PC work; the Dev Box is purpose-built for developers who want a dedicated machine for AI development.
Windows adds controls for AI agents
The event also highlighted Microsoft Execution Containers, which Microsoft says are generally available on Windows. The system is intended to let developers set boundaries around what an AI agent can access, including files and network resources.
Together, the hardware and software announcements show Microsoft’s approach: add more local computing capacity, give agents a way to operate within defined limits, and retain the cloud for work that needs it. The Surface Laptop Ultra is the most visible consumer-facing part of that plan, but the RTX Spark Dev Box and Windows agent controls point to a broader platform push.
