AMD Radeon HD 6790: specs and benchmarks

AMD Radeon HD 6790


AMD started Radeon HD 6790 sales 4 April 2011 at a recommended price of 149 USD. This is TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 1 GB of GDDR5 memory clocked at 4.2 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 134.4 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. Two 6-pin power connectors are required, and power consumption is at 150 Watt.

It provides poor gaming and benchmark performance at 12.46 percent of a leader's which is AMD Radeon R9 390 X2.
