AMD Radeon HD 6990M: specs and benchmarks

AMD Radeon HD 6990M

Summary

AMD started Radeon HD 6990M sales 12 July 2011. This is TeraScale 2 architecture notebook 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 card attached via MXM-B (3.0) interface. No additional power connector is required, and power consumption is at 100 Watt.

It provides poor gaming and benchmark performance at 10.81 percent of a leader's which is AMD Radeon R9 390 X2.
