Nvidia is unveiling its new GeForce RTX 2000 series of graphics cards at Gamescom in Germany today. While we’ve seen a number of teasers and plenty of card leaks recently, the GeForce RTX 2080 is finally official. Based on Nvidia’s new Turing architecture, the RTX 2080 is designed to succeed the popular GTX 1080 and push new real-time ray-tracing effects in upcoming games.

At Nvidia’s event, the company is unveiling the RTX 2070, RTX 2080, and RTX 2080 Ti. Nvidia is promising “up to 6X the performance of previous-generation graphics cards,” and real-time ray tracing for these cards. Asus, EVGA, Gigabyte, MSI, PNY, and Zotac will all have RTX 2080 and RTX 2080 Ti cards available for preorder today, with cards available on September 20th. RTX 2070 cards will start at $499, with RTX 2080 at $699, and the RTX 2080 Ti starting at $999.

Why Nvidia’s Turing GPUs are so intense

Ray tracing is a term you’re going to hear a lot now that Nvidia has announced professional and consumer graphics cards that use this technique to produce some of the most life-like simulations possible in games and other animations. So, what is ray tracing exactly, and how does it differ from current graphics rendering techniques?

The oversimplified answer is that ray tracing models the behavior of light in real time as it intersects objects in a scene.

It’s a feature that could lead to spectacular new graphics, but has been very hard to pull off because of the computational requirements. But Nvidia is tackling several issues facing ray tracing with a new graphics architecture known as Turing.
