We got some extra details about the upcoming Radeon HD 7990, the dual-GPU successor to the Radeon HD 6990 and the price tag is not something that many will like.

Since AMD went on record telling the world that fastest single core Radeon HD 7970 will sell for $549 as of January 9th, the dual-core card will obviously get a significant price boost. It won’t cost as much as two Radeon HD 7970 cards, but AMD plans to sell this card for $849 and according to the current launch schedule it should appear in March 2012.

The packs 2x3GB GDDR5 memory running at 5GHz effective, along with two Tahiti chips clocked at 850MHz, which amounts to 2x2048 stream processors 2x128 texture memory units and 2x32ROPs.

These prices can easily change by launch date, but as of today, this is the planned spec and price. The card specification looks impressive and ambitious and so is the rest of 2012, the year of 28 nanometer graphics.
