Alongside Nvidia's keynote at Computex, Microsoft announced a new Surface PC—the Surface Laptop Ultra—which will feature Nvidia's new RTX Spark superchip. This Microsoft and Nvidia team-up is the first of several major announcements we expect to see during Computex as the chip maker makes a play to power the next generation of premium laptops, with an emphasis on AI and gaming.
The Laptop Ultra expands Microsoft's consumer Surface line with more Windows on Arm technology, following years of Surface built on Qualcomm's Snapdragon X Arm processors. Unlike the Qualcomm chips, though, Nvidia's new RTX Spark superchip combines the processing might of Nvidia's DGX Spark and the graphics capability of an Nvidia RTX 5070 laptop GPU to power a new Windows-based agentic AI paradigm.
Slated to launch this fall, the Surface Laptop Ultra bridges the gap between thin-and-light ultraportables and beefy workstation laptops, offering the template for a new consumer category that can drive a full petaflop of AI-ready compute power. It's the next phase of evolution for AI PCs, combining Copilot+ features with the raw muscle to power on-device AI models and agents.
Inside the Surface Laptop Ultra
The Microsoft Surface Laptop Ultra is built around Nvidia's new CPU, the RTX Spark. This Arm-based superchip features 20 Grace compute cores, paired with 6,144 Blackwell RTX cores. This fusion of CPU and GPU muscle is combined with up to 128GB of unified memory, blowing past the limitations of smaller VRAM caches seen on dedicated GPUs.
The system is engineered around the Nvidia silicon, leveraging the high-efficiency hardware to deliver unparalleled power in a slim design. Microsoft says that the Surface Laptop Ultra will weigh less than 4.5 pounds and deliver all-day battery life—though the company has yet to specify the exact workloads used to calculate that longevity. (Gaming and AI workloads will shorten that estimation considerably, I expect.)
Other features are similarly premium, including 15-inch mini LED PixelSense Ultra touch screen, with up to 2,000 nits of peak HDR brightness. Inside is a high efficiency cooling system, optimized for the high compute and full array of CUDA cores inside. Port selection includes HDMI, USB-C, USB-A, headphone, and a dedicated SD card slot, alongside Microsoft's largest haptic trackpad to date. The all-metal chassis comes in two finishes: Platinum and Nightfall.
Rewriting Windows for the Age of Agentic AI
Microsoft is bringing a lot more to the table than just a spruced up laptop design for the new chip. The Surface Laptop Ultra is the flagship for this new architecture, officially joining the Copilot+ PC lineup, utilizing an integrated NPU in the RTX Spark to support Copilot features.
But Windows is also making some big changes to the operating system. Agentic AI is getting kernel-level execution for Windows apps, improving out-of-the-box support and opening up a broader ecosystem for frameworks like OpenClaw. Smarter Windows memory management will handle the 128GB of unified RAM, dynamically allocating resources for heavy GPU and AI tasks as needed.
The Prism emulation layer—which Windows on Arm uses to run x86 programs—gets new refinements and features thanks to Nvidia's involvement. We don't know the full scope of those improvements, but we won't have to wait long to learn more, since Microsoft Build is happening this week, and we expect the conference to include deep dives into the the revamped OS architecture.
Finally, a Thin-and-Light Built for Gaming
Gaming and anti-cheat and are both getting native support on Arm, marking a huge improvement for that growing segment of the Windows universe. Combined with the new Prism refinements, even non-native games and legacy creator tools will run smoothly on the new hardware, giving digital artists, developers, and gamers an immediate performance boost.
Major gaming studios like Riot Games and Krafton are bringing titles to Windows on Arm platforms, and native, cross-platform anti-cheat software should clear one of the biggest hurdles holding back competitive gaming on ARM-based PCs.

Microsoft signaled a new era of PCs when it launched the Qualcomm-based Surface back in 2024, calling it the beginning of the AI era. And this new Nvidia hardware signals the maturation of that early vision, offering a new level of power, driving use cases that, even recently, sounded like science fiction.
Pavan Dauluri, Executive VP of Windows and Surface, underscored this foundational evolution, noting, "At the end of the day, these devices bring together performance, efficiency, powering advanced local AI workflows in a portable form factor."
Cramming that kind of power and agentic capability into something that's lighter and slimmer than the average gaming laptop, and putting into a premium package comparable to a MacBook Pro, is a big step forward in this evolution.
As Surface Product Leader Andrew Hill plainly stated, "This is the most powerful thing we've ever made."
Release Timing and the Price of Ultimate Power
The Microsoft Surface Laptop Ultra will launch this fall, one of several new laptops running on the new Nvidia RTX Spark hardware. Currently, pricing information is not yet available, in part because laptop prices are quite dynamic right now due to the volatility of RAM prices. This will surely play a part in the price of a laptop with 128GB of unified memory.
Watch for further news this week as Microsoft Build brings us additional details around the Surface Laptop Ultra and the AI enhancements coming to Windows.
