AMD Radeon HD 6870: specs and benchmarks

AMD Radeon HD 6870

Summary

AMD started Radeon HD 6870 sales 21 October 2010 at a recommended price of $239. 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 1.05 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 220 mm. Two 6-pin power connectors are required, and power consumption is at 151 Watt.

It provides poor gaming and benchmark performance at 13.58 percent of a leader's which is NVIDIA GeForce GTX 1080 SLI Mobile.
