Microsoft unveils Surface Laptop Ultra and Dev Box on Nvidia RTX Spark
In June, Nvidia said it had secured agreements with Microsoft and a host of other PC makers to build AI- and agent-ready Windows PCs around its RTX Spark chip, but details on the machines were scant at the time. On Wednesday, at an event in San Francisco during the city's Tech Week, Microsoft filled in the picture.
The new Surface Laptop Ultra comes in two base models: one starting at $2,600 and one with a more powerful chip starting at $3,700. Prices rise with options for more memory and storage, up to $5,900. Microsoft says the highest-end device is already out of stock.
Microsoft also showed a workstation powered by the RTX Spark chip, the Surface RTX Spark Dev Box. It starts at $6,000 and comes with Microsoft dev tools including VS Code, GitHub Copilot CLI, WSL and PowerShell 7.
The pitch for both machines is that they can run AI models locally, on the device and for free, using the CPU, GPU, unified memory and hardware changes such as superior cooling. Both run a revamped version of Windows 11 with a feature called Execution Containers, which Microsoft says makes it easier to sandbox AI agents. CEO Satya Nadella said at the event that the feature will be available to all Windows 11 users.
Nadella framed the thinking behind it this way: "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." He said a harnessed layer is needed that can take multiple models plus context, memory and the action space, and that Microsoft is enabling it "not just for our apps but apps for anyone's agent. That's what the Windows platform is all about going forward."
The devices are clearly aimed at developers. Microsoft is offering up to $1,000 off for people who trade in a MacBook Pro, since Macs have become a popular choice for developers and AI agent enthusiasts, particularly in Silicon Valley. The company also promises that, given their graphics power, the Surface PCs can handle content creation, video processing and gaming.
Microsoft was not the only PC maker to give details on Wednesday. Dell announced the details of its previously announced Dell XPS 16 Creator Edition, another Nvidia RTX Spark Windows PC. It is available for preorder now at Best Buy for a later October delivery, priced at $3,800.
Key facts
- The Surface Laptop Ultra has two base models, starting at $2,600 and $3,700 (the latter with a more powerful chip), and rises to $5,900 with more memory and storage; Microsoft says the highest-end version is already out of stock.
- The Surface RTX Spark Dev Box workstation starts at $6,000 and ships with VS Code, GitHub Copilot CLI, WSL and PowerShell 7.
- Both run a revamped Windows 11 with Execution Containers, which Microsoft says makes it easier to sandbox AI agents; Nadella said the feature will be available to all Windows 11 users.
- Microsoft offers up to $1,000 off for trading in a MacBook Pro, signalling a developer-focused push.
- Dell's XPS 16 Creator Edition, also on RTX Spark, is $3,800 at Best Buy, preorder now for a later October delivery.
Why it matters
Nvidia's June announcement promised AI- and agent-ready Windows PCs on the RTX Spark chip but left the hardware vague. This event supplies the first concrete prices for Microsoft's own machines and for Dell's. It also shows how Microsoft sees Windows in the agent era: Nadella argued that a model alone does little, and that agents need orchestration, memory outside the model, and a harnessed layer combining multiple models, context, memory and the action space. Execution Containers is Microsoft's piece of that layer, offered, in Nadella's words, for apps from anyone's agent and not only Microsoft's.
Who it affects
Developers and AI agent enthusiasts are the clear target, which is why Microsoft is courting MacBook Pro owners with up to $1,000 off on a trade-in. Anyone running Windows 11 is affected by Execution Containers, which Nadella said will be available to all Windows 11 users. Buyers weighing a high-end Windows machine also get a second option in the Dell XPS 16 Creator Edition.
How to use it
The Surface Laptop Ultra starts at $2,600 for the base model, or $3,700 for the one with the more powerful chip, and goes up to $5,900 with extra memory and storage. The Surface RTX Spark Dev Box starts at $6,000 and arrives with VS Code, GitHub Copilot CLI, WSL and PowerShell 7 already set up. MacBook Pro owners can get up to $1,000 off by trading in. The Dell XPS 16 Creator Edition can be preordered at Best Buy for $3,800, with delivery later in October.
How solid is it
The prices and the Dell preorder come from the event and are stated plainly. The capability claims are the companies' own: that the machines run AI models locally and for free, that Execution Containers makes agent sandboxing easier, and that the PCs also handle content creation, video processing and gaming. No benchmark or performance figures for running AI models locally are given.
Risks and caveats
The highest-end Surface Laptop Ultra is already out of stock, according to Microsoft. No release or shipping date is given for the Surface Laptop Ultra or the Dev Box, and no timescale is given for when Execution Containers will reach all Windows 11 users. No technical mechanism of how Execution Containers sandbox agents is described. The Surface Laptop Ultra's chip names and memory and storage sizes are not listed, so the price tiers are hard to compare against the Dell.
