AMD Cape Verde Spawns Radeon HD 7770 and 7750 Graphics Cards by Add-in Partners
Today, AMD rolls out its mainstream performance oriented Cape Verde GPU clan with the Radeon HD 7770 and Radeon HD 7750 GPUs.
Adopting the same new GCN architecture as well as their 28nm fabrication process of the Tahiti GPU, the Radeon HD 7770 is the highlight of the Cape Verde GPU series as the first GPU clocked at 1000MHz. Also joining it is the Radeon HD 7750 GPU.
