Microsoft has officially unveiled its first Nvidia AI PCs, revealing the specs and pricing for the Surface Laptop Ultra and the Surface RTX Spark Dev Box. The announcement came Wednesday at an event held in San Francisco during the city’s Tech Week, following Nvidia’s June disclosure that it had secured agreements with Microsoft and a host of other PC makers to build AI- and agent-ready Windows machines on its RTX Spark chip.
At the time of that June announcement, details on the machines were scant. Microsoft has now filled in the gaps — and the lineup is clearly aimed at developers and AI power users who want to run models locally.
Surface Laptop Ultra Pricing and Models
The Surface Laptop Ultra ships in two base configurations:
A base model starting at $2,600
A more powerful chip variant starting at $3,700
Prices climb from there with options for additional memory and storage, reaching as high as $5,900. According to Microsoft, the highest-end device is already out of stock.
The Surface Laptop Ultra is the more portable of the two new machines, positioned for developers who want on-device AI without a full workstation. The company has not yet detailed exact shipping dates for every configuration, but the pricing tiers give a clear picture of where the lineup starts and where it tops out.
Surface RTX Spark Dev Box for Developers
Microsoft also introduced a workstation powered by the RTX Spark chip: the Surface RTX Spark Dev Box, priced from $6,000. It comes equipped with Microsoft developer tools including VS Code, GitHub Copilot CLI, WSL, and PowerShell 7.
The Dev Box is the heavier, more specialized option in the lineup. It is built for developers who need sustained performance for AI workloads rather than portability, and the bundled tooling reflects that focus.
Running AI Models On-Device
The core pitch for both the PC and the workstation is on-device AI. These machines are designed to run AI models locally — and for free — using the CPU, GPU, unified memory, and other hardware modifications such as superior cooling to handle the workload.
That combination matters because running models locally removes the need to send every request to the cloud. For developers testing agents, fine-tuning workflows, or running inference repeatedly, on-device execution can change how they work day to day. The hardware is built around that idea rather than treating AI as an afterthought.
Revamped Windows 11 and Execution Containers
Both devices run a revamped version of Windows 11 that introduces a feature called Execution Containers. Microsoft says this makes it easier to sandbox AI agents. CEO Satya Nadella said at the event that the feature will be available for all Windows 11 users.
Nadella explained the thinking behind the platform shift:
“One of the things we realized in the last 3-4 years is that just having a model doesn’t do much for anything. You really do need to orchestrate, and you need to have memory outside of the model. You need to have this harnessed layer that is able to take multiple models plus context, plus memory, and the action space.”
He added that Microsoft is enabling that capability “not just for our apps but apps for anyone’s agent. That’s what the Windows platform is all about going forward.”
In practical terms, Execution Containers give developers a safer way to run agents that take actions on a system. Sandboxing has become a central concern as agents move from answering questions to executing tasks, and Microsoft is positioning Windows 11 as the layer that manages that risk.
Aimed at Developers, With a MacBook Trade-In Offer
The devices are unmistakably targeted at developers. Microsoft is offering up to $1,000 off to customers who trade in a MacBook Pro — a nod to how popular Macs have become among developers and AI agent enthusiasts, particularly in Silicon Valley.
That trade-in offer is a direct signal about who Microsoft wants buying these machines. Developers have increasingly gravitated toward Macs for AI work, and the discount is designed to lower the cost of switching. Even so, Microsoft promises that these Surface PCs, with their powerful graphics processing, are also capable of content creation, video processing, and gaming.
Dell Also Reveals RTX Spark PC Details
Microsoft wasn’t alone in announcing specs for new Nvidia RTX Spark AI Windows PCs on Wednesday. Dell also shared details of its previously announced Dell XPS 16 Creator Edition. It is available for preorder now for a later October delivery at Best Buy, priced at $3,800.
Dell’s entry shows that the RTX Spark chip is not a Microsoft exclusive. Multiple PC makers are building around the same platform, which means buyers will soon have a broader set of options at different price points and form factors.
What This Means for AI PC Buyers
The launch signals a broader push toward machines built specifically to run AI agents and models locally rather than in the cloud. For developers weighing a switch, the combination of RTX Spark hardware, on-device model execution, and Windows 11’s new sandboxing tools makes this a lineup worth watching.
The pricing, however, places these devices firmly in premium territory. At $2,600 to $5,900 for the Surface Laptop Ultra and $6,000 for the Dev Box, these are not impulse purchases. They are tools aimed at people who expect to earn back the cost through AI development work.
For everyone else, the more important takeaway may be Execution Containers. If that feature rolls out to all Windows 11 users as Nadella said, the software side of this announcement could matter far beyond the people who buy the hardware.
