AMD Radeon HD 6770M: specs and benchmarks

AMD Radeon HD 6770M


AMD started Radeon HD 6770M sales 4 January 2011. This is TeraScale 2 architecture notebook card based on 40 nm manufacturing process and primarily aimed at office use. 1 GB of GDDR5 memory clocked at 3.6 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 57.6 GB/s.

Compatibility-wise, this is card attached via MXM-A (3.0) interface. No additional power connector is required, and power consumption is at 35 Watt.

It provides poor gaming and benchmark performance at 4.53 percent of a leader's which is AMD Radeon R9 390 X2.
