AMD did a sneak launch of the rumored HD 6930 and like NVIDIA GTX 560 Ti 448 it is in limited supply. The card sports a reduced Cayman core, but is not far behind HD 6950 in performance.
The world is preparing itself for the launch of AMD’s new flagship at 28nm; HD 7970 and therefore the new HD 6930 is not getting much attention. The card is based on a Cayman core with two more SIMD clusters deactivated over HD 6950, but will not launch globally. The card will only be sold in a few regions, where China is one of the more important.

HD 6930 is not coming to our part of the world, but can still be interesting to read about. Chinese Expreview has tested HD 6930 with 2GB memory and compared it to HD 6950 2GB and GTX 560 Ti 1 GB. The card is on average 6.15 percent behind HD 6950, and 9.48 percent behind GTX 560 Ti, which was to be expected. It might be that the card appears on more market later on, if AMD needs to empty out stock, but chances are pretty slim.
