The X800 is based on the latest (but not greatest) processor from ATi, the R430. With 12 pixel pipelines as opposed to 16 on the X800XL and X800XT, the X800 is closer to the X800pro, yet far cheaper. The Vertex engines on the other hand are 6, in all X800 products. However, the clock frequencies for the X800 are lower than that of the PRO as you can see in the table below.
The 256MB GDDR3 and the 256-bit memory bandwidth both point to a high-end graphics card. The memory type used is also extremely good but really goes to waste as the memory clock is set at a much lower frequency than the memory can handle.
