Radeon HD 7770 and HD 7750 specification announced

After the Radeon HD 7900 series, AMD will next week release the next line of its HD 7000 family with the AMD Radeon HD 7770 and HD 7750 targeting sub 200$ budgets buyers or what is known as Cape Verde GPUs.

Radeon HD 7770 and 7750, will feature GCN stream processors technology and use the latest 28nm process make it easy to AMD to put more stream processors up to 640 for the HD 7770 and 512 for the HD 7750, the Radeon HD 7770 is known as the first GPU that break the 1Ghz lock speed barrier, bellow full list of specification for both graphic cards leaked at 3dcenter:
