A year after the NVIDIA DGX Spark put a Grace Blackwell superchip into a Linux-only mini PC for AI developers, the same silicon is heading to mainstream Windows hardware. NVIDIA has confirmed that its new RTX Spark platform will power a wave of laptops and small desktops from Asus, Dell, HP, Lenovo, Microsoft, and MSI starting this fall.
Under the hood, RTX Spark is essentially the GB10 Grace Blackwell chip with Windows 11 on Arm support added. It pairs a 20-core Arm CPU with a Blackwell RTX GPU containing 6,144 CUDA cores, capable of up to 1 petaflop of local AI compute. The platform also supports up to 128GB of unified high-bandwidth memory, which is what makes NVIDIA's claim of running 120-billion-parameter local language models plausible on a workstation-class machine. For gaming, NVIDIA is targeting AAA titles at 1440p and 100 fps, with native support for Epic's Easy Anti-Cheat, BattlEye, and Xbox services on Arm.
That same GB10 silicon has already proven itself in open-source workloads on the Linux-based DGX Spark, where tools like Ollama, llama.cpp, and Open WebUI run natively on Ubuntu 24.04, and collaboration with the open-source community has delivered an average 35% performance uplift on state-of-the-art models. Native Linux support for RTX Spark consumer devices has not been announced, but kernel-level work is progressing: NVIDIA engineers are extending the Nova driver, a Rust-written open-source GPU kernel driver already merged into the mainline Linux kernel, to cover the Blackwell GPU architecture.
The Arm transition remains the elephant in the room. Microsoft has continued investing in its Prism x86 emulator and is leaning on developers to ship native Arm builds. The company points out that Blender, DaVinci Resolve, Cinema 4D, Redshift, Topaz Photo, CapCut, Cubase, Bitwig Studio, Affinity by Canva, Adobe Photoshop, and Premiere all already run natively on Arm. That list matters more than usual here, because RTX Spark's target audience leans heavily toward creators and developers rather than general consumers.
The announced lineup includes the Asus ProArt P14, P16, and Mini PC, the Dell XPS 16 Creator Edition, the HP OmniBook X 14 and OmniBook Ultra 16, the Lenovo Yoga Pro 9i, the Microsoft Surface Laptop Ultra, and the MSI Prestige N16 Flip AI+. Neither NVIDIA nor its partners have shared pricing or specific launch dates, and leaked references to lower-cost variants of the chip (previously known as the N1X) have not yet materialized in any official roadmap. With the existing DGX Spark workstation listed at $4,600 (€4,232), the first RTX Spark systems are expected to land in the premium tier when they ship later this year.
