Codenamed 'New Zealand', the 7990 is AMD's highest end and most powerful card to come from the Southern Islands architecture, the last of the Southern Island range before Sea Island hits.
Consisting of two Tahiti XT GPUs and 6GB GDDR5 memory (special edition 7990s could reach 12GB), Radeon HD 7990 goes head to head against the GeForce GTX 690.
By default, AMD has the advantage in terms of 50% more video memory (GTX 690 has 4GB), significantly higher memory bandwidth and the new Turbo mode, technology similar to the Turbo mode used on NVIDIA Kepler-based cards with a few major differences.

Wait! Did I read that correctly? Possible 12GB of RAM on a GPU?
Boards are already starting to be sampled in preparation for the launch in the second half of July. There is no word on pricing yet as this will likely come closer to release.
Do you think 12GB of RAM is overkill or crazy or is it fantastic? Discuss in our forums.
