"This monster card is listed as having 5.1 billion transistors (between the two GPUs),5,210 stream processors 5120SP and 160 texture units per core. The 8990 is also listed as having 48 ROPs per core and a pair of 384-bit buses. Memory is expected to be anywhere in the range of 6GB to 12GB and should be clocked from the factory at 1,250MHz. Each GPU will ship running at 950MHz, according to the roadmap."
