    R520 - talk, rumours, speculation, inane smiley-laiden junk; the lot!

    Ok I've gotten this passed along to me on the low-low from two different anonymous sources now, I was gonna post it up in the other 520 pipe thread to explain my mirth at a few comments....but it's already wisely closed.

    So what kind of beast would the above quote make the R520?

    Particularly, what does "new rasterizer" mean?

    You can see here what the G70 rasteriser looks like and here you can find the R480 rasteriser setup. So take your pick on what's new in the rasteriser for R520...

    "16 pixel units, four quad groups, 8 MIMD vertex units"

    I left out the part about new rasterizer, but why would such a unit be called anything but a 16 pipe architecture?
    The vertex units are independent of the pixel pipes, and while the above arch. would have an advantage over a 16pixel pipe 6vertex pipe unit, it certainly isnt a 24 pipelined arch.
    Both the X8x0 XT/XL series and the 6800GT/U series had 16 pixel pipes, four quad groups, and no one tried to pass them off as anything else.

    R520 = 16/16/24, 3 ALUs per pipe, 8 vertex, 600+ MHz

    8) :)

    I'm going to a wild stance here but I'm thinking the r520 is a bit closer to the xbox 360 then we were orginally thinking, just got wind of this, its very possible it does have unified shaders.

    It is not at all a similar architecture to Xenos, that is confirmed.

    Well, I think several of us have slowly been edging left to right on that scale. I'm not that far over to the right yet tho.

    Edit: Not to mention I'd have to apologize to NV and VR Zone! :lol: I can do it tho --I'm a married man; lots of practice!

    Xenos is R500, right? :|

    ya, Xenos = R500 = C1


    (although ATI does not like it being called 'R500' , because one might get the idea because of the number that it is inferior / less powerful to R520)

    Thanks Wunderchu, I admit I haven't heard it referred to as C1 either. :oops:

    R520 won't be nearly as efficient, and I doubt it will have a dughter die with eDRAM on it.

    If anything it will still be 16 pipes but with more ALU's for the shaders. I have not a clue.

    Re: R520, let's redefine "pipes" a bit....

    A NV40 on steroids with more VS units :p

    Launching 26 Aug? I can't think what else they'd be launching with that description.

    There had been a little banner ad at an Australian site for this before, but this looks more official-like.

    [Just in case somebody suddenly turns deep red and it disappears --and props to Ady at R3D for finding this]

    Have they launched CrossFire yet? As in LAUNCH? :) But lets hope it's R520.

    /me prays.

    That is not what is usually called a rasterizer in the 3D pipeline. The rasterizer is the unit that generates quads from triangle data.

    Which fits better with the "feed" language. But what would you do to that which would make it worthwhile to highlight? That's typically been considered pretty standard, unexciting stuff, hasn't it?

    Could this be a sideways reference to the new internal bus?
