NVIDIA RTX Spark 笔记本今日开售，主打 128GB 统一内存与本地 AI

NVIDIA's RTX Spark laptops went on sale worldwide today, with up to 128GB of unified memory and 1 petaflop of FP4 AI performance, starting at $2,599. The machines pair a Blackwell RTX GPU with a Grace CPU and CUDA, run large language models and AI agents locally, and add agent permission controls plus inference serving over a home network.

Why it matters: RTX Spark puts local model running, coding and testing inside a Windows laptop, cutting how much the dev loop depends on cloud test environments.
