NVIDIA RTX Spark laptops go on sale October 16; a single chip holds as much as 128GB of unified memory, and AI agents can run on the machine itself

一句重點：In these laptops, the Grace CPU and the Blackwell RTX GPU sit together on one superchip. The first models come from MSI, Microsoft, Lenovo, HP, Dell and ASUS, and NVIDIA announced on October 16 that these Windows laptops were going on sale (NVIDIA press release).

發生什麼事

Shared memory is the headline feature: the CPU and GPU share up to 128GB. For running agents and large language models right on the machine, the 1 petaflop (FP4) of AI compute that NVIDIA lists is enough. On the CPU side, the custom design had input from MediaTek (NVIDIA press release).

No command line is needed to install agents such as Perplexity, OpenClaw, Hermes and GitHub Copilot; NVIDIA has prepared a guided setup for that. Which permissions agents get is up to OpenShell and Microsoft Execution Containers. Some RTX Spark configurations can also run Nemotron 3.5 Bolt 74B-A9B 24GB, an NVIDIA model tuned for tool calling (NVIDIA press release).

Correction (2026-10-22)

The headline and Bottom line originally put the sale date as today; they now give October 16, the press release date. Links to the press release were also added to the Bottom line and the pricing paragraph.
