AMD could reveal the first details on the new Navi 20 video cards already at CES 2020 in Las Vegas. AMD recently introduced the new Radeon RX 5500 and RX 5300 graphics cards. The Sunnyvale company's response to NVidia Ampere, however, could be products based on the Navi 20 architecture.

Navi 21, 22, 23

Contrary to what one might think, lower numbers represent the most powerful graphic solution. The word "Lite" should however indicate a lower profile version, with low energy consumption or in any case intended for portable systems.
Navi 23 would be destined to compete with NVidia RTX 2080 and with its Ti variant, perhaps surpassing them in terms of performance and presenting itself as a top-of-the-range GPU. According to sources close to the company, also 21 and 22 would be able to compete with Ampere.
The AMD RDNA 2 architecture will lead to the transition to the 7nm + production process, a leap forward very similar to what NVidia will probably do with Ampere: competition from a technical point of view therefore seems it will be really interesting.

The graphics cards of the Navi 20 series could be presented close to the Computex 2020, around the end of May next year. However, it is possible that AMD can offer a preview as early as January, during the CES in Las Vegas.
