Nvidia announces RTX Spark chips combining unified memory, RTX graphics, and a new N1 CPU for Windows laptops, positioning them as the first devices that may genuinely deliver on the 'AI PC' promise.

Nvidia announced RTX Spark chips at Computex in Taiwan over the weekend. The chips combine unified memory, RTX graphics, and Nvidia's new N1 CPU, and will be available in Windows laptops from HP, Asus, Dell, and Lenovo, as well as Microsoft's Surface Laptop Ultra.

RTX Spark laptops will feature up to 128 GB of unified memory and graphics performance comparable to a discrete RTX 5070, plus CUDA software that allows developers to access GPU cores—capabilities previously unavailable in the Windows ecosystem outside integrated solutions.

Some reports estimate high-end RTX Spark laptop configurations will cost over $4,000. Smaller form-factor desktop versions are also coming, with lower-tier configurations expected to appeal to gamers and creators alongside AI enthusiasts.
