7700 series
In the coming week, AMD will release its Radeon HD 7700 series, which aims to increase its competitiveness in the sub-$200 market. The latest specifications exposé reveals AMD's new design strategy: Instead of increasing components such as stream processors and ROPs, which would increase transistor counts, and unnecessarily increase power draw, AMD is counting on a lesser number of better-configured Graphics CoreNext stream processors. While the previous-generation HD 5770/6770 "Juniper" GPU featured VLIW5 stream processors, the new "Cape Verde" GPU, which will go into making up Radeon HD 7770 and 7750, will feature GCN stream processors. Apart from architectural performance improvements, AMD is counting on increased clock speeds to do the trick. The specifications are listed below.

28 nm = DDR4 Start Up....
DDR4 is 30 nm part & expectations are by end of year some DDR4 will be ramping, with 2015 being 50% DDR4.
