Nvidia launches RTX Spark laptops that run full Windows 11 on Arm with Prism emulation, enabling all Windows apps and demanding games with anti-cheat support, marking a major step for Windows on Arm PCs and local AI workloads.

Fourteen years after Microsoft’s initial unsuccessful attempt to run Windows on an Nvidia Arm chip with the original Surface PC, Nvidia is reintroducing Arm-powered Windows laptops with its RTX Spark platform. Scheduled for debut on October 16, 2026, these RTX Spark laptops aim to run the full Windows 11 experience with broad compatibility for legacy applications, creative software, and demanding games, overcoming the limitations that doomed the first generation of Windows on Arm devices.

At Nvidia's recent Editor’s Day in San Francisco, the company emphasized that RTX Spark laptops can run “all your apps, all your games, everything” on Arm hardware, facilitated by Microsoft’s Prism emulator. This software translates x86 instructions to Arm in real time, enabling compatibility with existing Windows programs including Adobe Creative Suite, Microsoft Office, Blender, and games requiring kernel-level anti-cheat systems.

This vision draws inspiration from past transitions such as Apple’s switch to Arm silicon with Rosetta 2 and Qualcomm’s initial Windows on Arm platforms, yet Nvidia aims to surpass those in performance and usability. Unlike earlier Qualcomm Snapdragon Windows laptops, which struggled with gaming compatibility and anti-cheat software leading to errors or limited titles, Nvidia’s RTX Spark packs GPU power akin to an Nvidia RTX 5060 discrete laptop graphics card. This more robust GPU, combined with collaborations with game developers, supports anti-cheat for titles like Fortnite, Roblox, Rainbow Six Siege, and is expected to extend to Call of Duty, PUBG, Valorant, Apex Legends, and others.

While some CPU-heavy games experience performance slowdowns due to emulation overhead, most are graphics-bound and benefit from the powerful Blackwell GPU architecture inside RTX Spark. Early tests show smooth 1080p gameplay for challenging titles like Cyberpunk 2077, with options to play at higher native laptop resolutions with DLSS upscaling and frame generation technologies.

RTX Spark laptops come with a high price tag, reflecting their top-end specs and AI capabilities. For example, Microsoft’s Surface Laptop Ultra variant starts at $2,600 with fewer cores and memory, scaling up to $5,900 for a configuration with 20 CPU cores, 6,144 GPU cores, and 128GB unified memory to handle large local AI models. Nvidia acknowledges these as early iterations, indicating future lower-cost models are planned.

The introduction of RTX Spark signals a significant advance for Windows on Arm computing, marrying full software compatibility and gaming performance with local AI processing prowess. Nvidia’s push also complements ongoing Qualcomm efforts, potentially raising the overall quality and ecosystem for Arm-based Windows devices. As such, Nvidia’s initiative could broaden the horizons for Arm PCs, facilitating a future where “everything” runs efficiently on Arm architecture under Windows.
