Summary
AMD started Radeon HD 6850 X2 sales 19 September 2011. This is a desktop graphics card based on a TeraScale 2 architecture and made with 40 nm manufacturing process. It is primarily aimed at gamer market. 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
of a leader's which is NVIDIA GeForce RTX 4090.
