Nvidia Unveils Personal AI Agent Devices

量子位 · wechat · 2026-07-12

At BW, Nvidia showcased two new devices powered by Grace CPU + Blackwell GPU, connected via NVLink-C2C, and equipped with 128GB unified memory: the consumer-facing RTXSpark laptop/desktop and the developer-focused DGXSpark desktop supercomputer.

RTXSpark: For Personal Agents and Creators

Positioned as a "local personal agent" device, it can run 120B parameter models locally with a maximum context length of 1 million tokens.
The accompanying OpenShell runtime allows users to restrict agent executable actions, keeping sensitive information local and desensitizing data before sending it to the cloud.
It also emphasizes creative and gaming capabilities: handling heavy 3D scenes, supporting 12K 4:2:2 video decoding, and stabilizing AAA game framerates at 100FPS+ in 1440p.
Multiple game publishers have expressed support for Arm-native games, and a live demo featured the Arm-native version of Naraka: Bladepoint.

DGXSpark: A Desktop AI Supercomputer for Developers

Featuring the same 1 Petaflop peak computing power and 128GB unified memory, but designed for proof-of-concept, fine-tuning, and inference.
Supports models with up to 200B parameters, and can handle even larger models when two devices are networked together.
A live demo showcased a personal agent based on the Qwen 35B multimodal model: generating a webpage from a hand-drawn sketch locally in just tens of seconds.

Nvidia also launched the GeForce Collector's Card Series, featuring 14 free collectible cards highlighting historical milestones in GeForce history.
