Donanim Haber now claims that PowerColor’s HD 7970 X2 Devil 13 will actually be called PowerColor HD 7990 Devil13. Also the first specification details surface. PowerColor HD 7990 is said to feature 6GB of GDDR5 memory split into 3GB sections for each core, this would operate on 768-bit interface (384×2). HD 7990 would feature a core clock of 1 GHz (there is no data about the boost clock). The final cooling design should not be very different than the one already shown. There is however no information about the final price.
