6,144 Blackwell RTX GPU cores set the ceiling on Nvidia's N1X, the Arm-based chip confirmed for RTX Spark laptops in October.

The top-of-line N1X configuration pairs that GPU with a 20-core Grace CPU and a unified memory pool spanning 24GB to 128GB. Nvidia says this configuration ships in both high-end laptops and miniature PCs.

Microsoft's Surface RTX Spark is among the mini PC form factors the company named. The N1X launches in two configurations.

The high-end variant carries the 6,144-core Blackwell GPU, the 20-core Grace CPU, and the wide memory range. The second configuration targets the mini PC segment.
