After much speculation, one that should be the final version of the Radeon HD 7000 had revealed settings. The new 7990 is a dual-GPU, with the tough task of competing with the Nvidia Geforce GTX 690. The plate will be sold from April 25 priced at around U.S. $ 1000.
The Radeon HD 7990 will have two Tahiti XT GPUs, clocked to 1 GHz speed reached by the rough work of a total of 4096 Stream Processors (think of these as Stream Processors individual processing cores). In addition, the board will have 6 GB of GDDR5 RAM memory accessed through a 384-bit interface (768 if you add up the value of each GPU).
