ATI Radeon HD 3850 technical specs and benchmarks

ATI Radeon HD 3850

Summary

ATI started Radeon HD 3850 sales 19 November 2007 at a recommended price of 179 USD. This is a TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at gamers. 0.5 GB of GDDR3 memory clocked at 1.66 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 53.1 GB/s.

Compatibility-wise, this is 1-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 208 mm. An additional 1 6-pin power connectors are required, and power consumption is at 75 Watt.

It provides poor gaming and benchmark performance at 15.05 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.
