We said a few months ago that NVIDIA drives two projects in parallel. The GT200 65nm that got launched and branded as GeForce GTX 280 and GTX 260 is out and there is a GT200 55nm chip that should be launched shortly. Our sources are telling us that 55nm version of the chip should be ready either in late August or in September, which means that the Radeon HD 4870 X2 card will get some competition. And that is only natural as NVIDIA wants to maintain their good track record of being on top of the game with their products, but also able to advertise and sell these to the worldwide. This die shrink to 55nm will surely make a change for the better with some extra gaming experience. - FudZilla

NVIDIA Die Shrink GT200 55nm Comes by September

We believe that shaders and clocks of 55nm GT200 are definitely going to be higher than the 65nm and the chip itself should be a bit cooler. This means the R700 will get some better competition, and the fact that this ATI's dual card is going to end up faster than the GeForce GTX 280 doesn't mean ATI has already won the war. All remains still to be seen how good the Radeon HD 4870 X2 will turn out, but also what the die shrink will main for the GT200 chip in the end. Though such a die shrink always brings great added value and new performance figures with renewed gaming experience.
