NVIDIA RTX Spark is a superchip platform for slim Windows laptops and compact desktops, combining AI, graphics and general-purpose computing for local AI, content creation and gaming. The superchip connects an NVIDIA Grace CPU with up to 20 cores and an NVIDIA Blackwell RTX GPU with up to 6,144 CUDA cores through an NVLink C2C interconnect, sharing up to 128GB of unified memory between CPU and GPU. Fifth-generation Tensor Cores support FP4 precision for up to one petaflop of AI compute, letting AI models and 3D scenes share memory rather than duplicate data across separate pools. Locally, RTX Spark runs AI models with up to 120 billion parameters and one million tokens of context, renders 3D scenes over 90GB, edits 12K video and plays AAA games at 1440p above 100 frames per second. Laptops as thin as 14mm are planned for fall 2026.
