ATI Radeon HD 3870: specs and benchmarks

ATI Radeon HD 3870

Summary

ATI started Radeon HD 3870 sales 19 November 2007 at a recommended price of $269. This is TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at office use. 512 MB of GDDR4 memory clocked at 2.25 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 72.1 GB / s.

Compatibility-wise, this is Dual-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 241 mm. 1x 6-pin power connector is required, and power consumption is at 106 Watt.

It provides poor gaming and benchmark performance at 0.58 percent of a leader's which is NVIDIA GeForce GTX 1080 SLI Mobile.
