really ?

didnt know about that...
Yes, this is true and the reason for this is because HW T&L of the R3x0 and prior cores is not working as advertised... in fact it's broken.

T&L on ATI cards is mainly done by the main CPU and not by the graphiccard (VPU) as it should be, therefore when using games or benches with require heavy CPU workload, the performance of Radeons drops proportionally more dramatically than on GeForce cards.

This explains also why high-end GeForce cards run great on slower systems where high-end Radeons need more CPU horsepower to unleash their real performance.
