Last week we already made mention of the fact that AMD's partners are developping X2 versions of the radeon 7900 series, thus Dual-GPU products.
Donim haber leaked photo's of the Radeon HD 7970 X2 Devil13. It is a dual GPU based solution thar comes with PowerColor's Vortex III cooling solution.
Again, the card is a custom-design dual-GPU graphics card and thus has two 28 nm Tahiti GPUs setup internally in CrossFire configuration. There's no info available on the number of shder processors and clock frequencies. The two GPUs however would hold 6 GB of GDDR5 memory / 384-bit memory bus. The card takes power from a whopping three 8-pin PCI-Express power connectors, and has a rated TDP of 525W.
