ATI Radeon HD 4770: specs and benchmarks

ATI Radeon HD 4770

Summary

ATI started Radeon HD 4770 sales 28 April 2009 at a recommended price of $109. This is TeraScale architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 512 MB of GDDR5 memory clocked at 3.2 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 51.2 GB / s.

Compatibility-wise, this is 2-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 203 mm. 1x 6-pin power connector is required, and power consumption is at 80 Watt.

It provides poor gaming and benchmark performance at 6.02 percent of a leader's which is NVIDIA TITAN V.
