ATI plans to focus their efforts on developing smaller, more energy efficient GPUs for the mainstream market, and then integrating multiple chips into one card for the high-end crowd.
We took two chips and put it on one board (X2). By doing that we have a smaller chip that is much more power efficient.
We believe this is a much stronger strategy than going for a huge, monolithic chip that is very expensive and eats a lot of power and really can only be used for a small portion of the market.
