A few weeks ago AMD launched their Radeon HD 7700 Series. The cards use the all-new Cape Verde graphics processor which is based on AMD's new GCN Graphics Core Next architecture that promises increased performance and lower power draw.
Cape Verde is a downscale from the "Tahiti" silicon, on which higher Radeon HD 7900 series parts are based. There are fewer number of redundant components, so Cape Verde is left functionally-identical to Tahiti, but is smaller, built for more affordable graphics cards. Cape Verde also retains the basic hierarchy of the architecture as implemented in Tahiti.
