AMD Radeon HD 6990 technical specs and benchmarks

AMD Radeon HD 6990

Summary

AMD started Radeon HD 6990 sales 8 March 2011 at a recommended price of 699 USD. This is a TeraScale 3 architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 2x 2 GB of GDDR5 memory clocked at 5 GHz are supplied, and together with 2x 256 Bit memory interface this creates a bandwidth of 2x 160.0 GB/s.

Compatibility-wise, this is 2-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 295 mm. An additional 2 8-pin power connectors are required, and power consumption is at 375 Watt.

It provides good gaming and benchmark performance at 30.06 percent of a leader's which is AMD Radeon R9 390 X2.

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.
