According to them, the previous release date has been moved to next month. VR-Zone has earlier claimed that we might see HD 7990 in late July, well, this is not going to happen.
AMD has recently adjusted their prices of all Radeon HD 7000 Series graphics card just before NVIDIA launches its most anticipated Kepler-based mid-range segment – GeForce GTX 660 (Ti) and GTS 650.
VR-Zone reports that the Radeon HD 7990 powered by two Tahiti XT GPUs (not XT2), will be equipped with four mini-DisplayPorts and two Dual-DVI display outputs. Additionally, card is expected to require four 6-pin power connectors — not two 8-pin’s as reported earlier. Moreover the CrossFire link will be handled by the PLX chip (just like GeForce GTX 690). Unfortunately, there is no word about 12GB version of HD 7990, so we might not see this model at all.
