GTX 560 Ti = 8 Units
GTX 560/GTX 460 = 7 Units
GTS 450/GTX 550 Ti = 4 Units

The 6970 takes the same performance hit from tessellation as the 560 Ti, which places well below that of the 570 when it comes to tessellation performance specifically.

It's one of the reasons why my 470s are faster than a 6990 or 6970CF in Heaven, 3DMark11, and Crysis 2.
Where did you get that info?

I can't find one source to cover them all, however if you Google Nvidia PolyMorph you'd be on the right track.
