ATI Radeon HD 3850 X2 technical specs and benchmarks

ATI Radeon HD 3850 X2

Summary

ATI started Radeon HD 3850 X2 sales 4 April 2008 at a recommended price of 349 USD. This is a TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at gamers. 2x 0.5 GB 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. Its power consumption is at 140 Watt.

It provides poor gaming and benchmark performance at 20.36 percent of a leader's which is AMD Radeon R9 390 X2.

Compatibility, dimensions and requirements

Information on video card compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus - if the video card is inserted into the slot instead of being soldered to the notebook motherboard.
