GeForce FX Architecture Explained

Posted by CowboyNeal on from the kicking-the-tires dept.

Brian writes "3DCenter has published one of the most in-depth articles on the internals of a 3D graphics chip (the NV30/GeForce FX in this case) that I've ever seen. The author has based his results on a patent NVIDIA filed last year and he has turned up some very interesting relevations regarding the GeForce FX that go a long way to explain why its performance is so different from the recent Radeons. Apparently, optimal shader code for the NV30 is substantially different from what is generated by the standard DX9 HLSL compiler. A new compiler may help to some extent, but other performance issues will likely need to be resolved by NVIDIA in the driver itself."

    Is that the politically correct way of saying "performance sucks"?

      Wrong Linus. If he'd used the full quote it would have been clear, "Grow up, Charlie Brown."

      I can see why he didn't though, no one really does that. Especially using the last name too. That is just way too melodramatic, and unrealistic.

    "he has turned up some very interesting rasing or lifting up regarding the GeForce FX" ?

    probly revelations would be better.

    someone programmed the shaders to work with glide... i can't help hoping 3Dfx will perform some voodoo and ressurrect from nVidia's ashes. excuse me now, i must go stroke my voodoo5

    Experience:

    GeForce FX is really noisy

    Explanation:

    It sucks in large amounts of air to keep it cool. This is one of two ways a GeForce FX sucks. The other way is beyond the scope of this post.

    Does the FX architecture involve cheating on benchmarks? :)

    Yes, it's common practice to pay websites to post articles about why your product sucks. Don't let anyone tell you that the bad press might possibly hurt business, that's a lie.
