Club3D joined the HD 7700 party by launching its pair graphics cards, the Radeon HD 7770 (CGAX-7772) and Radeon HD 7750 (CGAX-7752). The two cards appear to be contract-manufactured by TUL, the company behind PowerColor and VTX3D, as the card designs bear a striking resemblence to those by the two brands. The HD 7770 of course is based on AMD's reference board and cooler designs, with a red-colored PCB. The HD 7750, on the other hand, features a refreshing single-slot cooler. The HD 7700 packs 640 GCN stream processors, and feactures clock speeds of 1000 MHz core, and 1125 MHz (4.50 GHz GDDR5 effective) memory; while the HD 7750 packs 512 stream processors, with clock speeds of 800 MHz core and 1125 MHz (4.50 GHz GDDR5 effective) memory.
