    The architecture overview of the G92 covers this.

    48.76% different, or so someone told me.

    Davros, you mean the site has a front page and an articles index? ;)

    I looked and didn't see that.

    So the 9xxx series is pretty much the same as the g80?

    Yes, the G80 is very similar to G92.

    The G92 compared to GT200 covers most of all the changes between the G80 and GT200.

    I see. So no revolutions in graphics processing like going from vector to scalar in the near future??

    the G80 did that :D. It has scalar ALUs, and so do Intel IGPs and S3's DX10.1 GPU.
    Though it's still actually a 16-wide or such SIMD or MIMD thingy, "thread-wise" rather that "vector components-wise" (or both). While data still is vector based, because it's vector based.
    You'll maybe find an explanation that doesn't suck in some threads about 3D architecture here on B3D.

    I get the jist of the architectures and that the vector code is redone into scalar by the system, but was wondering if anything earthshaking like an actualy useable raytracer was coming down the line sooner than 2045...
