    What's the source for that? I was referring to this:

    Q: How is NVIDIA approaching the tessellation requirements for DX11 as none of the previous and current generation cards have any hardware specific to this technology?



    Jason Paul, Product Manager, GeForce: Fermi has dedicated hardware for tessellation (sorry Rys :-P). We’ll share more details when we introduce Fermi’s graphics architecture shortly!
    Like I said, though, the two claims aren't necessarily inconsistent.

    The tesselation is done via the "polymorph" engines attached to shader units (and feeding directly into them). While I'm not 100% sure of the details, I think the shader units are still used to handle some extra processing before the final rasterising step.
    The end result is some good parallel geometry magic, but it might suffer a little if the scene is more concerned with pixel/fragment shaders (pipeline stalls would really hit it hard here - the usual parallel programming problems).

    Power hog?

    http://www.legitreviews.com/news/7489/

    ...On the side of some retail boxed graphics cards it states that a minimum 600W or greater power supply (with a minimum +12V current of 42A) is needed for proper operation...

    your are, of course, correct. Severe case of braindeadness on my part.

    I just want to see numbers on these things. I want some Linux benches too, but I guess we'll have to wait until some users get their hands on one.

    heise.de (german) has managed to snag some benchmarks.

    GTX 470 scores somewhere between HD 5850 and HD 5870, unless you're benchmarking almost pure tesselation.

    *yawn*

    But even card vendors won't get the final specifications before monday, so let's wait a few days for leaks.
