Possible AMD Radeon HD 7700 Series Specs Revealed

With AMD reportedly set to release its Radeon HD 7700 series next week, we get our first peek at the specifications of the HD 7770 and HD 7750.

As report first of February in a leaked roadmap, AMD is set to release its HD 7700 series graphics cards based on the Cape Verde. Based on information coming out of German-based 3dcenter.org, we may have our first glimpse at the full specifications for the new Cape Verde series. The HD 7700 series will utilize AMD's GCN stream processors seen with the HD 7900 series. With the HD 7770 series, you'll have a base core-clock speed of 1 GHz, with performance falling between the HD 6850 and HD 6790, at a suggested price around $150 dollars. The HD 7750 should equal performance of the HD 6770/5770 in performance, at a suggested price of around $125 dollars.
