AMD Radeon HD 6870 technical specs and benchmarks

AMD Radeon HD 6870

Summary

AMD started Radeon HD 6870 sales 21 October 2010 at a recommended price of 239 USD. This is a TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 1024 GB of GDDR5 memory clocked at 1.05 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 134.4 GB/s.

Compatibility-wise, this is 2-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 220 mm. An additional 2 6-pin power connectors are required, and power consumption is at 151 Watt.

It provides poor gaming and benchmark performance at 14.33 percent of a leader's which is NVIDIA Quadro P6000.

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.
