AMD Radeon HD 7700 Series Cards

AMD will release its Radeon HD 7700 series graphics cards sometime in the next week. The new "Cape Verde" GPU aims to increase AMD's competitive edge in the sub-$200 market. This new design appears to focus more on a smaller number of better-configured Graphics Core Next stream processors being paired with higher clock speeds to further improve performance over the previous generation. AMD is counting on these changes to offer better performance while keeping transistor counts and therefore power consumption in check. Stay tuned for our review of the AMD Radeon HD 7700 series when it launches later next week.
