TAIPEI: Microsoft reveals the Surface Laptop Ultra and Surface RTX Spark Dev Box, its first hardware lineup built around Nvidia’s new RTX Spark superchip.
The company announces the Surface Laptop Ultra at Computex 2026 on June 2. The Surface RTX Spark Dev Box debuts hours later at Microsoft Build in San Francisco. Both devices target developers and creators building local AI workloads on Windows.
The Surface Laptop Ultra packs up to 128GB of unified LPDDR5X memory shared across CPU and GPU. A 20-core Arm-based Grace CPU pairs with a Blackwell GPU featuring 6,144 CUDA cores. Microsoft claims one petaflop of AI performance, enough to run models up to 120 billion parameters locally.
The chassis measures under 18 millimeters thick and weighs less than 2 kilograms. A 15-inch MiniLED PixelSense Ultra display delivers 2,000 nits peak brightness in HDR. Microsoft positions the device directly against Apple’s current MacBook Pro lineup.
Photoshop, Blender, DaVinci Resolve, Cinema 4D, CapCut, and Topaz Photo all run natively. The Prism emulator now supports RTX Spark GPU acceleration for x86-dependent software. League of Legends, Valorant, PUBG, and Alan Wake 2 confirm support at launch.
The Surface RTX Spark Dev Box uses the same chip in a desktop mini-PC form factor. The aluminum chassis features 1,000 air vents arranged in a grid pattern. The 100-watt thermal envelope handles long training jobs, agentic AI pipelines, and local fine-tuning.
Visual Studio Code and GitHub Copilot come preinstalled on the Dev Box at shipping. Microsoft positions both devices as the foundation for agentic Windows experiences.
Dell, HP, Lenovo, ASUS, Acer, MSI, and Gigabyte also build RTX Spark devices. Both Microsoft products ship later in 2026 with pricing not yet announced.
The launch marks Microsoft’s most aggressive Windows-on-Arm push to date.
