Some manufacturers doesn’t respect the Summer peace and one of these is AMD that is getting ready to ship out its flagship. Radeon HD 7990 is code-named New Zealand and gets 3 GB GDDR5 for each graphics circuits, a total of 6 GB.
Many were shocked that Nvidia launched Geforce GTX 690 with dual graphics circuits by the end of April, despite AMD had a headstart with the HD 7900 series. There have much going back and forth since then when it comes to HD 7990. VR-Zone now reports that AMD is planning to launch HD 7990 by the ned of July and that he has seen the complete press material.

Radeon HD 7990 sports two Tahiti XT graphics circuits, each with 3 GB GDDR5 memory with 384-bit memory bus access. In total the card will sport 4096 Radeon cores, 256 texture units and 64 raster units. The big question is how high it will be clocked and how it will measure up to GTX 690. The only thing certain is that HD 7990 will get the same Turbo Boost technology that appeared with HD 7970 GHz Edition.
In our tests of HD 7970 GHz Edition AMD managed to present a performance card on the level with GTX 680, at the cost of higher energy consumption. GTX 690 performs nearly as good as two GTX 680 with a TDP (Thermal Design Power) at 300 watt, and we can’t imagine that AMD will be able to do the same in terms of energy efficiency even if they may very well hit the same level of performance as Nvidia’s top performer.
Manufacturing partners have the card in hand, but we can only wait and see if the card actually launches this time, or if it once again disappears. The price is still unknown.
