FUD Zilla heard a dual-GPU card based on NVIDIA's GK104 will be released next quarter.
Nvidia needs something with two chips to hold the water before the GK110 comes along, since GK110 is the real high-end chip that was intended to fight in the high end market. However, the GK110 will not be ready in months and by the time it appears AMD’s next generation could be just around the corner. In fact, it would be unfair to even compare the GK110 to current generation Radeons, which will be more than nine months old by the time GK110 shows up.
We think that Nvidia will have to reduce the clock and shave a few shaders off the GK104 in order to put two chips on a single card, as currently a single GK104, GTX 680 card ends up close to 200W TDP.
According to German tech site 3D Center, the card will be named GeForce GTX 690 and the launch date may be May.
