Fillrate Multi Texturing
When multitexturing is employed, the ranking changes. The FX cards can render four dual textured pixels, just like the ATi cards. Due to the FX's higher clock speeds, the ATi cards are unable to keep up.

This test sees the Radeon 9800 fall quite a ways behind. One possible explanation would be that the FX carries a fixed-function T&L engine in addition to its vertex shader engine, which would explain its clear lead. (Thanks to Dave @ Beyond3d.com.)
