Nvidia Confirms N1X Name For RTX Spark Windows PC SoC
Nvidia is positioning local AI, not gaming, as the reason to buy this class of PC: it recommends 48GB or more for running models on the machine and says smaller configurations will lean on cloud processing.
Reporting from 1 source: 4Gamer.net.
Nvidia detailed its RTX Spark system on a chip for Windows PCs at a technical briefing in the United States on October 8, after Microsoft, ASUS, MSI and others announced machines built around it the previous day. Nvidia calls the part RTX Spark N1X and denied the existence of a rumored lower-tier N1. Memory comes in five LPDDR5X-9400 capacities from 24GB to 128GB.
The briefing followed the hardware announcements by a day and settled a naming question. The SoC is RTX Spark N1X, matching the rumor that preceded the June 2026 announcement, and Nvidia denied that a lower-tier N1 exists.
The N1X shares its semiconductor die with GB10, the part in the DGX Spark machine for AI developers, so the same silicon ships under two names depending on the PC. Memory ranges from 24GB to 128GB of LPDDR5X-9400. Configurations below 64GB belong to notebooks; desktops come in 64GB and 128GB.
