The X800XL card utilizes ATi's chipset, codenamed R430. The R430 is equipped with 16 pixel pipelines and 6 vertex engines just like the X800XT and unlike the 12-pipeline X800 Pro. This fact makes the XL more like like a lower-clocked X800XT. Also, unlike its predecessors, it is manufactured through a 0.11 micron process.
The GPU clock of the X800XL ticks at 400MHz. That's 120MHz less than the X800 XT PE which unfortunately, is a very large difference to expect to cover through overclocking. The frequency for the 2ns Samsung memory modules is by stock set at 490MHz.
In the following table you can see a sum-up of the major differences between the most popular high-end ATi cards:
