AMD Radeon HD 6850 X2 technical specs and benchmarks

Summary

AMD started Radeon HD 6850 X2 sales 19 September 2011. This is a TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 2x 2 GB of GDDR5 memory clocked at 4.2 GHz are supplied, and together with 2x 256 Bit memory interface this creates a bandwidth of 2x 134.4 GB/s.

Compatibility-wise, this is 2-slot card attached via PCIe 2.0 x16 interface. An additional 2 8-pin power connectors are required, and power consumption is at 254 Watt.

It provides poor gaming and benchmark performance at 18.15 percent of a leader's which is NVIDIA TITAN Xp.

Technical specs

Quantitative parameters such as shaders number, GPU core clock, manufacturing process, texturing and calculation speed. These parameters indirectly say of video card performance, but to be more precise you have to review it's benchmark and gaming test results.

Compatibility, dimensions and requirements

Information on video card compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus - if the video card is inserted into the slot instead of being soldered to the notebook motherboard.
