The Radeon HD 6850 was a mid-range graphics card by AMD, launched in October 2010. Built on the 40 nm process, and based on the Barts graphics processor, in its Barts PRO variant, the card supports DirectX 11.2. The Barts graphics processor is an average sized chip with a die area of 255 mm² and 1,700 million transistors. Unlike the fully unlocked Radeon HD 6870, which uses the same GPU but has all 1120 shaders enabled, AMD has disabled some shading units on the Radeon HD 6850 to reach the product's target shader count. It features 960 shading units, 48 texture mapping units and 32 ROPs. AMD has placed 1,024 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 775 MHz, memory is running at 1000 MHz.
Being a dual-slot card, the AMD Radeon HD 6850 draws power from 1x 6-pin power connectors, with power draw rated at 127 W maximum. Display outputs include: 2x DVI, 1x HDMI, 2x mini-DisplayPort. Radeon HD 6850 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 198 mm in length, and features a dual-slot cooling solution. Its price at launch was 179 US Dollars.
