GeForce 6800 XT: specs and benchmarks

Summary

NVIDIA started GeForce 6800 XT sales 30 September 2005. This is a desktop graphics card based on a Curie architecture and made with 110 nm manufacturing process. It is primarily aimed at gamer market. 256 MB of GDDR3 memory clocked at 0.6 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 38.4 GB/s.

Compatibility-wise, this is a single-slot graphics card attached via AGP 8x interface. 1x Molex power connector is required.
