Nvidia's half hearted established the supply of dual-chipset videoadapter GeForce GTX 690. In turn, the competing Radeon HD 7990 is seriously delayed, although previously the release for late July was planned.
According to new information, AMD will officially unveil the video card, code-named New Zealand in the second half of August. Non-reference Radeon HD 7970 X2 from HIS, PowerColor and other AMD exclusive partners will debut, apparently, even later.
Most likely, Radeon HD 7990 will be announced at the annual exhibition Gamescom (Cologne) 16 to August 19. This is one of the few Premier Advanced Micro Devices, which will take place on the European continent: usually the company prefers to organize similar events in their home countries or in countries in South-east Asia.
Radeon HD 7990 GPU is equipped with two Tahiti XT (2x 2048 shader, 2x 128 TMU, 2x 32 ROP), two 384-bit memory buses and 2x 3 GB of RAM on-board of type GDDR5. Among other things, the card will support dynamic overclocking GPU. The advantage of New Zealand in comparison with GeForce GTX 690 will be the simultaneous support of six displays Eyefinity 6 via video outputs Dual-Link DVI (2) Mini DisplayPort (4). It is not excluded special edition versions of the Radeon HD 7990 with 12 GB of graphics memory.
AMD engineers have decided to resort to an unusual combination of additional power connectors — four PCI-E Power 6-pin. This will ensure a stable supply of power to the chips Tahiti XT, switch PLX PCI-E 3.0, and 24 chips GDDR5. Radeon HD 7990 will obviously be cheaper than the 1000 dollar GeForce GTX 690.
