ATI started Radeon HD 4870 sales 25 June 2008 at a recommended price of $299. This is TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at gamers. 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 250 mm. Two 6-pin power connectors are required, and power consumption is at 150 Watt.

It provides poor gaming and benchmark performance at


of a leader's which is NVIDIA GeForce RTX 3080 Ti.
