With Nvidia's new Kepler set to release this month, we are now hearing that AMD has the Radeon HD 7990 ready in the wings.
Right before the New Year, we learned about the upcoming "New Zealand" graphics card, which is based on two "Tahiti" HD 7900 series graphics chipsets. With Nvidia set to release its first 28 nm based Kepler card later this month, Fudzilla reports that AMD plans to launch the Radeon HD 7990 just weeks after NVIDIA introduces its new GeForce GTX 680.
Though the final specifications are not known, it is rumored the HD 7990 will feature a core clock of 850 MHz, memory clock of 1250 MHz (5 GHz effective), 6 GB GDDR memory (3 GB per GPU), with 384-bit (x2) memory bus. It will be based on a PCIe 3.0 interface and support for DirectX 11.0 and OpenGL 4.0. In addition, the card will include 62 compute units for a total of 4096 (2048 x2) stream processors, 256 (128 x2) texture units and 64 (932 x2) full color ROPs.
The one thing we do know based on past experience with AMD's dual-GPUs, is the Radeon HD 7990 will be 1) expensive (suggested price around $850 dollars) and 2) a lengthy graphics card (over 11.5 inches). For those Nvidia fans, I wouldn't worry too much, as it is rumored that Nvidia already has its own dual GK104 card ready to counter attack.
Don't like Radeon products? Don't post. Pretty simple. Until real world benchmarks (not NVIDIA based marks) come out for the 680, the 7970 is still king in single GPU setups.
