❯ Nvidia’s RTX Spark N1X ships in October in 20-core and 18-core configurations

shippingNvidia confirmed the RTX Spark N1X launches in October in two configurations: a 20-core CPU with a 6,144-core Blackwell GPU, and an 18-core CPU with a 5,120-core GPU. The chips go into Windows laptops and mini PCs.

the specNvidia’s broader stated figures pair a 20-core Grace CPU with a Blackwell GPU for up to 128GB of unified memory and 1 petaflop of AI performance. Unified memory is aimed squarely at Apple — over the past year high-end Macs became the least troublesome machines for local inference precisely because of that architecture, with demand strong enough to cause shortages. Nvidia is filling the same slot directly.

local inferenceThe people affected are developers buying hardware to run models locally. 128GB of unified memory lets a class of models that previously required the cloud land on a desktop, and that demand is exactly what drove high-spec Mac prices up this year. Watch the actual retail price and supply after the October launch — if pricing does not hold, Apple’s route still works out cheaper.

▪ SIGNALPutting unified memory into Windows laptops targets not gamers but the local-inference users Apple took over the past year.
