AMD Radeon HD 6770: specs and benchmarks

AMD Radeon HD 6770

Summary

AMD started Radeon HD 6770 sales 21 January 2011 at a recommended price of $129 . This is 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 128 Bit memory interface this creates a bandwidth of 76.8 GB/s.

Compatibility-wise, this is 2-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 198 mm. 1x 6-pin power connector is required, and power consumption is at 108 Watt.

It provides poor gaming and benchmark performance at 9.41 percent of a leader's which is AMD Radeon R9 390 X2.
