AMD Radeon HD 6990M technical specs and benchmarks

AMD Radeon HD 6990M

Summary

AMD started Radeon HD 6990M sales 12 July 2011. This is a TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 2 GB of GDDR5 memory clocked at 3.6 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 115.2 GB/s.

Compatibility-wise, this is MXM Module card attached via MXM-B (3.0) interface. An additional None power connector is required, and power consumption is at 100 Watt.

It provides poor gaming and benchmark performance at 11.72 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.
