At each price category NV GF100 (and derivative chips) has superior performance/watt in
Tessellation.
The link you provided for the power consumption, tests Crysis and not a DX-11
Tessellation game or benchmark. I clearly talked about DX-11
Tessellation performance/watt and in order to see that, you really have to test a
real Tessellation game or benchmark not Crysis in DX-10.
Have a look at TessMark OpenGL,

You really need to understand that
Tessellation in DX-11 API is not programmable (Hull-Shader and Domain-Shader are programmable) and the only way to get more performance is to install more Tessellators in the architecture of your Graphics card, thats why NV GF100 is a multicore (Multi-tessellation cores) design and only 69xx has dual core design from AMD, HD58xx and HD68xx series are single-Tess Core designs.
Next gen AMD architecture GCN (Graphics Core Next) will utilize a
multi-Tessellation core design much like NV GF100/110.
Im talking about Tessellation and you keep saying that AMD cards have better performance/watt in general use, have you a problem understanding what Im talking about ??
Why not test HD6870 against GTS550 in Tessellation and observe witch card has better performance/watt ?? Even GTS450 can keep up against HD5870 or HD6870 in Tessellation.
