ATI Radeon HD 3850 AGP: specs and benchmarks


ATI started Radeon HD 3850 AGP sales 3 January 2008. This is TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at office use. 512 MB of GDDR3 memory clocked at 1.66 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 53.0 GB / s.

Compatibility-wise, this is 1-slot card attached via AGP 8x interface. 1x 8-pin power connector is required, and power consumption is at 75 Watt.

It provides poor gaming and benchmark performance at 2.18 percent of a leader's which is NVIDIA GeForce GTX 1080 SLI Mobile.
