AMD Radeon HD 6850 X2: specs and benchmarks

AMD Radeon HD 6850 X2

Summary

AMD started Radeon HD 6850 X2 sales 19 September 2011. This is TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 2 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 Dual-slot card attached via PCIe 2.0 x16 interface. Two 8-pin power connectors are required, and power consumption is at 254 Watt.

It provides poor gaming and benchmark performance at 6.91 percent of a leader's which is NVIDIA GeForce RTX 2080 Ti.
