I just did a quick lookup of ATI's card line-up and found this:
9800 Series
256bit memory Interface
AGP8x
Support for Smartshader 2.1
Support for HyperZ III+
8 pipelines
4 shaders
X600 Series
128bit memory interface
x16 PCI-X (theoreitcally AGP16X)
Support for Smartshader 2.0
Support for HyperZ III
4 pipelines
2 shaders
Now unless Im mistaken, that's a case of a top generation-old card beating the snot out of a midrange current generation card -- since maybe the GF2Ultra vs GF3Baseline, that's not happened... troubling that ATI would choose to do that
