Microsoft and Nvidia Unveil RTX Spark Laptops with Arm-Based Windows Experience
By Drooid · · How we work
Launch and Core Features
Microsoft and Nvidia held a joint launch in San Francisco to introduce the first RTX Spark laptops. The devices pair an Arm-based CPU with Nvidia’s Blackwell GPU and a unified memory architecture, enabling local AI agents to be installed from the Windows Store in a two-click “Get Started” flow. At launch, three agents—Hermes, Perplexity and OpenClaw—are officially supported, with additional agents such as Meta’s Muse slated for future addition.
Technical Optimizations
Because the laptops run Windows on Arm, Microsoft has upgraded its Prism emulator to translate x64 applications to the Arm microarchitecture. The company ships monthly compatibility updates and has tuned emulation for each core. Memory handling is a focal point: the Surface Laptop Ultra can be configured with up to 128 GB of unified memory, and a slider in Nvidia’s Windows app lets users allocate more of that pool to the GPU on 24 GB or 32 GB models. Gaming support has been bolstered through anti-cheat partnerships and an advanced shader-delivery system that pre-compiles shaders for faster launches.
Official Statements & Responses
Peter Dawoud, principal program manager at Microsoft, said the team is continuously adding features to expand the range of AI experiences on Windows and that each RTX Spark platform receives monthly updates to improve compatibility. He highlighted “incredible investments” in unified memory to maximize model loading while preserving system responsiveness. Dawoud also emphasized the extensive work put into delivering a true RTX gaming experience on Arm. Adrienne Brewbaker, senior director of Windows marketing, announced that Copilot Plus PC features will roll out to Windows Insiders later in the year, following a partnership with Nvidia.
Performance and Gaming Outlook
In on-hand testing, medium graphics settings with DLSS at 1440p delivered a stable 60 fps in most titles, comparable to a high-end MacBook Pro but below the performance of dedicated gaming laptops. Resolution or setting adjustments may be needed for more demanding games. Copilot Plus PC features such as Recall are not available at launch and are expected to arrive in the next year.
