The Radeon HD 6770 Green Edition was a graphics card by AMD, launched in April 2013. Built on the 40 nm process, and based on the Juniper graphics processor, in its Juniper LE variant, the card supports DirectX 11.2. The Juniper graphics processor is an average sized chip with a die area of 166 mm² and 1,040 million transistors. Unlike the fully unlocked Radeon HD 6770, which uses the same GPU but has all 800 shaders enabled, AMD has disabled some shading units on the Radeon HD 6770 Green Edition to reach the product's target shader count. It features 720 shading units, 36 texture mapping units and 16 ROPs. AMD has placed 2,048 MB GDDR3 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 700 MHz, memory is running at 667 MHz.
Being a dual-slot card, its power draw is rated at 86 W maximum. Display outputs include: 2x DVI, 1x HDMI, 2x mini-DisplayPort. Radeon HD 6770 Green Edition is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 170 mm in length, and features a dual-slot cooling solution.
