AMD Radeon HD 7700 Graphics Cards Officially Launched

AMD’s Radeon HD 7700 graphics cards are now official. The series is based on the Cape Verde GPU that is made using the 28nm fab process and uses the Graphics CoreNext GPU architecture. Fully enabled, it features 10 GCN compute units resulting to a total of 640 stream processors accompanied by 40 TMUs, 16 ROPs, and a 128-bit wide GGDR5 memory interface.

The series features two cards – the Radeon HD 7770 which AMD brands as the “GHz Edition” and the Radeon HD 7750. The Radeon HD 7770 features a core clock speed of 1000MHz and memory speed of 1125MHz (4500MHz effective). It is AMD’s first graphics card to come with a reference clock of 1000MHz and has all of the features of the Cape Verde GPU fully enabled. That includes all the 640 stream processors, 40 TMUs and 16 ROPs all working. The card comes with 1GB of GDDR5 memory and requires a single 6-pin PCIe power connector.

The Radeon HD 7750 on the other hand only has 512 stream processors and 32 TMUs because only 8 of its 10 GCN compute units are enabled. It also has a lower core clock of 800MHz. All other details from here are similar to the Radeon HD 7770 including the 1125MHz (4500MHz effective) memory clock and 1GB of GDDR5 memory attached to a 128-bit memory interface. No PCIe power connector is required for this card.

The Radeon HD 7770 is selling around $159 while the Radeon HD 7750 is cheaper at only $109. Asus, Sapphire, MSI, Gigabyte, HIS, XFX, PowerColor and VTX3D have all launched their own Radeon HD 7700 graphics cards.
