At Computex 2026 NVIDIA announced RTX Spark, an Arm-based CPU built for on-device AI and agent features in Windows, launched in close partnership with Microsoft and headed to multiple OEM laptops as early as this fall.
NVIDIA publicly unveiled RTX Spark at Computex 2026 in Taipei, introducing an Arm-based CPU that the company says is designed to place AI agents and multimodal workloads at the center of the PC. The announcement highlighted a two and a half year collaboration with Microsoft and demonstrated a native Windows experience that will expose agent features directly from the taskbar. NVIDIA said some Spark systems could reach customers as early as this fall.
NVIDIA positioned RTX Spark as a reinvention of the PC for the age of AI, claiming up to 1 petaflop of AI performance, full‑stack graphics capabilities, and support for up to 128GB of unified memory. The company described Spark as "the most efficient PC chip ever built," while acknowledging that public performance metrics, detailed hardware specifications, and final pricing were limited at the announcement.
Microsoft is presenting the Surface Laptop Ultra as the flagship Spark machine for "world builders," pairing a 15‑inch mini‑LED PixelSense Ultra touchscreen with the lineup's largest haptic touchpad to date. Microsoft said the Surface Ultra is optimized for an NVIDIA Blackwell RTX GPU alongside RTX Spark and will support dynamic allocation of up to 128GB of unified memory to accelerate 3D rendering and multimodal creative workflows.
Dell and Asus framed their Spark models toward creative professionals. Dell's XPS 16 Creator Edition combines a tandem OLED panel with True Black HDR 600, promises all‑day battery life, and keeps an SD card slot plus HDMI. Asus' ProArt P14 and P16 offer up to 128GB unified memory, up to 2TB local storage, a haptic touchpad and a Lumina Pro tandem OLED at 3,840 × 2,400 resolution; Asus said it will replace its historic DialPad with haptic controls.
MSI showed a convertible Spark model, the Prestige N16 Flip AI Plus, which supports the Nano Pen stylus but was released with limited configuration details. NVIDIA also named other major OEM partners — HP, Lenovo, Acer and others — indicating a broad vendor rollout of Spark across laptops and desktops rather than an exclusive family of machines.
For builders and developers the practical implications are mixed: unified memory pools up to 128GB and on‑device petaflop‑scale AI compute promise richer local agent and multimodal workflows, but the absence of independent benchmarks, detailed power and thermal data, and final pricing leaves open how Spark will compare to Intel, AMD and Qualcomm CPUs in real‑world tasks. NVIDIA and Microsoft framed Spark as foundational to "reinventing Windows," and reports indicate typical Spark configurations will sit well above $2,000, suggesting these will be premium creator machines.
