AMD Radeon HD 6670 technical specs and benchmarks

AMD Radeon HD 6670

Summary

AMD started Radeon HD 6670 sales 19 April 2011 at a recommended price of 99 USD. This is a 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 64 GB/s.

Compatibility-wise, this is 1-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 168 mm. An additional none power connector is required, and power consumption is at 66 Watt.

It provides poor gaming and benchmark performance at 5.92 percent of a leader's which is AMD Radeon R9 390 X2.
