A picture posted by @AMDRadeon shows AMD’s product manager for high-end discrete desktop graphics, Devon Nekechuk, holding a Radeon HD 7990 – really huge and sexy card!

There is no information yet about its specs but taking in consideration that some vendors like Asus and Powercolor already sell dual HD 7970 cards known as HD 7990, one can imagine that the “official” Radeon HD 7990 should be faster than the currently selling products. Just guessing.
