Originally scheduled for a June launch, AMD is apparently still finalizing the product is now rumored to be prepping a launch at GamesCon in Cologne, Germany, between August 15 and 19.
An article published by VR-Zone suggests that the very limited availability, dual-GPU card will integrate a four 6-pin PCIe interface to manage the power supply for the Tahiti XT core, 3 GB GDDR5 memory per core and a PLX PCIe 3.0 controller. The report also claims that the monstrous card will have six physical display outputs with four mini-DisplayPort and two DVI links.
Pricing is, of course, even more speculation than the product itself, as availability will largely determine the price of this low-volume card. However, it is reasonable to assume that the 7990 will be more expensive than the model it replaces - the 6990 currently retails in the $700 to $900 range - while it will be cheaper than Nvidia's expensive, 4 GB GTX 690. Depending on the retailer, GTX 690 models currently sell for just under $1,000 to more than $2,700 at this time, with the majority of cards circling the $1,100 territory.
