Performance Rating

The Radeon HD 6850 X2 was a graphics card by AMD, launched on September 19th, 2011. 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 X2 to reach the product's target shader count. Radeon HD 6850 X2 combines two graphics processors to increase performance. It features 960 shading units, 48 texture mapping units, and 32 ROPs, per GPU. AMD has paired 4 GB GDDR5 memory with the Radeon HD 6850 X2, which are connected using a 256-bit memory interface per GPU (each GPU manages 2,048 MB). The GPU is operating at a frequency of 800 MHz, memory is running at 1050 MHz (4.2 Gbps effective).
