I don't need to ask for clarification, I know misleading market-speak when I see it.

A fast CPU can calculate some billions of simple operations per second. A very fast GPU can calculate a little bit more than a trillion even simpler operations per second.

To evaluate thirty trillion complicated operations (a body shape) per second requires nothing less than a supercomputer.

You sound ignorant.  He's probably referring to his algorithms that statistically cull a large number of possibilities to come up with the skeletal map.  The sensor doesn't do anything but feed it 3D and 2D data, the processing is done on the xbox.

I'd tell you to go to read his papers, but that'd probably be too much effort for you since you think you know more than he does about his work.  I'll take his word over what you think you know.

Yes that's exactly what I think he means... which you might have noticed if you read my earlier post in the thread.

Culling out trillions of impossibilities is very different from evaluating something trillions of times per second. The latter makes it look like you have very fast hardware, even if what you're doing amounts to simply picking one correct answer out of trillions possible (i.e. the calculator example I gave).

And please cut the crap like "you sound ignorant" without pointing out a mistake in what I'm saying.
