    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.
