The difference is that ATI has a fixed function unit for tessellation, while nvidia does it on the SPs. Nothing wrong with that if it's still faster. Granted we don't know yet how it will perform, but I would say with a lot of certainty that it will be faster/better than RV870.

Trying to do graphics,phycis and tessellation your going to have to take a hit somewhere

Not necessarily, if you can efficiently code in order to make idle units be close to 0 at each clock

Curious but how would you know it's a "small" hit?

Considering PhysX has its own performance hit, and sometimes it isn't that small, so how do you know that is so? Of course, Nvidia knows there aren't any tesselation games out right now it seems, but its still that's quite an assumption

You can't have a slightest idea if tesselation is going to be faster on dedicated hardware or "CUDA core"...

Your all missing a key fact! Microsoft and Ati are basically becomming partners. The xbox has tesselator technology because it has a ati gpu. Microsoft wants to implement dx as close to and with ati as possible, because its good for both of thier buisinesses. If microsoft benefits through the xbox to have exclusive advantages, it has all the reasons to back ati and thier vision of 3d graphics.
