NVIDIA said on October 13 that the first RTX Spark laptops launch on October 16. RTX Spark is a single superchip for Windows 11 PCs that pairs a Grace CPU of up to 20 cores with a Blackwell RTX GPU, with up to 128 GB of unified memory and up to 1 petaflop of FP4 AI compute. NVIDIA says it runs models of up to 120B parameters with a 1M-token context, and laptop makers include ASUS, Dell, HP, Lenovo, Microsoft and MSI. The same announcement introduced Nemotron 3.5 Bolt, a 74B mixture-of-experts model with 9B active parameters that fits in 24 GB using 2-bit quantization.

## Why it matters locally

It puts DGX Spark-class memory in a laptop, but NVIDIA's porting guide lists about 300 GB/s of bandwidth, so expect generation speeds near DGX Spark and Ryzen AI Max systems rather than a desktop RTX card.
