The Radeon HD 7770 GHz Edition was a mid-range graphics card by AMD, launched on February 15th, 2012. Built on the 28 nm process, and based on the Cape Verde graphics processor, in its Cape Verde XT variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. The Cape Verde graphics processor is an average sized chip with a die area of 123 mm² and 1,500 million transistors. It features 640 shading units, 40 texture mapping units, and 16 ROPs. AMD has paired 1,024 MB GDDR5 memory with the Radeon HD 7770 GHz Edition, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1000 MHz, memory is running at 1125 MHz (4.5 Gbps effective).
Being a dual-slot card, the AMD Radeon HD 7770 GHz Edition draws power from 1x 6-pin power connector, with power draw rated at 80 W maximum. Display outputs include: 1x DVI, 1x HDMI 1.4a, 2x mini-DisplayPort 1.2. Radeon HD 7770 GHz Edition is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 210 mm in length, and features a dual-slot cooling solution. Its price at launch was 159 US Dollars.
