    Hmm 2 slot cooler, 400MHz clock, 16x AA, 16/32x0 pipes, 8 shader units per pipeline? Can't wait to see the mermaid demos :]

    I can host, but I got circuit class till 12:25, if no one else does, i can do it

    Its hardly worth a look.

    Just NV PR.

    8 shader units per pipeline and 16 pipelines...

    Someone tell me how Nvidia gets away with telling one lie after the next and everyone still thinks they are cool?

    Do you have any idea how many Transistors it would take to actually make that statement true?

    Guess I was lucky to see the page :)

    Damn, that is one very impressive architecture. It may be 222 million transistors, but they'll do a lot more than double NV30's shader performance, especially since texture instructions don't prevent a simultaneous arithmetic instruction anymore.

    I still think R420 will keep pace in shader speed, because most of the time you can pair a texture op with an ALU op (at least with current shaders like in HL2 and Doom3), so R300/R420 should have similar per-pipe performance to NV40 according to that diagram. R420 should have a higher clock too, right?

    Now it just a question of how efficient all that is. Each pipe is clearly FAR more transistor efficient than NV30's pipe yet also more capable, so they may well have sacrificed FIFO sizes or other aspects.

    Do any of you still think we'll see RGMSAA? Doesn't look like it to me, in which case Vegetto-eX's pics may well have been real.

    Congrats to NVidia. Looks like the developers dream chip.

    Aren't they saying 2 shader units = 8 ops over the 4 components (RGBA) of a pixel = 2 ops * 2 quads?

    RGBA stands for red, green, blue, alpha right?

    What does the alpha channel actually do?
