Nvidia launches its most ambitious PC platform yet with RTX Spark Superchip

Nvidia has unveiled the RTX Spark Superchip, a Windows on Arm platform designed to power a new generation of agentic AI PCs capable of running long‑context models and autonomous workflows locally. The chip combines 20 Arm CPU cores, a Blackwell GPU with 6,144 CUDA cores, and up to 128GB unified memory, enabling 120‑billion‑parameter models, million‑token contexts, and high‑end creative workloads like 12K video editing. Nvidia expects over 30 laptops and around 10 desktops to launch this fall, including a new Surface Ultra, all promising high performance, long battery life, and consistent plugged‑in or unplugged performance. The platform also targets creators and gamers with 1440p 100 FPS gaming and fully GPU‑accelerated Adobe apps rebuilt specifically for RTX Spark.
