ATI started Radeon HD 4870 X2 sales 12 August 2008 at a recommended price of $550. This is a TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at office use. 1 GB of GDDR5 memory clocked at 3.6 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 115.2 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 267 mm. One 6-pin and one 8-pin connectors are required, and power consumption is at 286 Watt.

It provides poor gaming and benchmark performance at


of a leader's which is NVIDIA GeForce RTX 4090.
