Radeon X850 XT: specs and benchmarks

Summary

ATI started Radeon X850 XT sales 1 December 2004. This is a desktop graphics card based on a R400 architecture and made with 130 nm manufacturing process. It is primarily aimed at gamer market. 256 MB of GDDR3 memory clocked at 1.08 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 34.56 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 1.0 x16 interface. 1x 6-pin power connector is required, and power consumption is at 69 Watt.
