AMD Radeon HD 7990 delayed again
AMD's flagship dual-GPU graphics card, Radeon HD 7990, has been delayed again. Originally touted for a June launch, then delayed until July, it is now expected to be available around the middle of August. Featuring two Tahiti XT cores (not the newer Tahiti XT2, used in the 7970 GHz edition cards), it will be AMD's top-end card.
Each GPU on the card will have 2048 GCN cores, 128 TMU and 32 ROPs, along with 3 GB GDDR5 memory per GPU. The memory will be clocked at 1.5 GHz (6 GHz effective), although the core clock speed has not been announced. It will have a PLX PCI-E 3.0 controller.
For power, the card will have an unusual combination of power connectors, taking 4 6-pin connectors, instead of the more common 8-pin connectors. This means the card will be capable of drawing 375W. On the rear of the reference design card, there will be enough outputs to support 6 displays, with 4 mini-DP and 2 DVI ports.
Pricing is not yet known, but VR-Zone speculate that it will be cheaper than NVidia's GeForce GTX 690, and they say it should be available during GamesCom event in mid-August, which will take place in Cologne, Germany.
