AMD Radeon HD 6670: specs and benchmarks

VS

Summary

AMD started Radeon HD 6670 sales 19 April 2011 at a recommended price of $99 . This is a TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at office use. 1 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 single-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 168 mm. No additional power connector is required, and power consumption is at 66 Watt.

It provides poor gaming and benchmark performance at 1.87% of a leader's which is NVIDIA GeForce RTX 4090.
