ATI Radeon HD 3850 X2: specs and benchmarks

ATI Radeon HD 3850 X2


ATI started Radeon HD 3850 X2 sales 4 April 2008 at a recommended price of $349. This is TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at office use. 2x 512 MB of GDDR3 memory clocked at 1.66 GHz are supplied, and together with 2x 256 Bit memory interface this creates a bandwidth of 2x 53.0 GB / s.

Compatibility-wise, this is 2-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 267 mm. No additional power connector is required, and power consumption is at 140 Watt.

It provides poor gaming and benchmark performance at 4.59 percent of a leader's which is NVIDIA TITAN V.
