ATI Radeon X800 GTO: specs and benchmarks

Summary

ATI started Radeon X800 GTO sales 29 December 2007. 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. 128 MB of DDR memory clocked at 0.7 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 22.4 GB/s.

Compatibility-wise, this is single-slot card attached via PCIe 1.0 x16 interface. No additional power connector is required, and power consumption is at 49 Watt.
