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
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.
