Nvidia first unveiled its GeForce RTX series of graphics cards for desktop PCs last summer. The RTX 2070, RTX 2080, and RTX 2080 Ti were all designed for high-end gaming PCs, and they enabled new ray-tracing capabilities — a groundbreaking graphics technique that models light in real time as it intersects objects in a virtual scene — in games like Battlefield V.

Nvidia held back at the time from announcing any plans to bring RTX beyond desktop machines, but today at CES, the company said it’s finally ready to bring those new graphics chips — including a mobile RTX 2080 — to gaming laptops.
