This is also confirmed by AMD, the tesselation engine in 68xx is much improved compared to previous 58xx-series GPU's. It's about twice as fast at lower levels of tesselation.. though this advantage goes down with higher levels of tesselation. See this graph from xbitlabs comparing 68xx tesselation vs. 58xx.

.. Though AMD are still behind nvidia Fermi GF100 when it comes to tesselation.
You will find that the 6870 and 6850 are not far behind their predecessors overall, and in CrossFire they scale even better than "old" 58xx.. though they have less raw "GPU"-power, they are better optimized for their task.
