I very much doubt that AMD didn't improve tessellation performance. I'm of the mind that the "leaked" benchmarks point to what we should see out of Cayman in regards to tessellation performance.

I don't think the problem is the tessellation unit but more than likely there is another bottleneck that they have addressed to improve the performance.
one unit is fine if it can handle it but it in some places it can't so more is better to split the work up with.
The only bottleneck I've seen is that one 5870 isn't accessing memory as fast a two 5770 can.
