    1360 SP for 5850 and 1600 for the 5870?
    Hmm... so it will be 750 MHz for the 5850 and same or more for the 5870.

    Haha, u see that writing down there? I think its saying "ComputerBase" and that means its old. It was "Smarter Choice" under the AMD Logo but it was chopped with "The Future is Fusion" as u can see with the BG color.

    Oh, might be fake then, after all? :p

    If it is true it does seem to have 1600. Only thing that gets me is that it doesn't seem color full enough for an AMD slide. Kinda reminds me of graphs and such from Chinese sites.

    It can always surprise me, when a person, who can draw such a nice diagram, is unable to remove a logo and use correct colours...

    All those gotchas not withstanding, I blew up the image and I saw these unique things (not in rv7xx),

    -Parallel DMA engine
    -Memory Read/Write cache
    -Stream output reduction buffers
    -Video controller
    -1 less display controller
    -no sideport
    -no uvd
    -Programmable tessellator cache
    -Something that looks like Isaard controller. I have no idea what exactly it is?

    The "video controller" would no doubt be or include UVD, if it was real

    Oh, so 3 independent display controllers? Would be very nice.
    Every radeon (except the very first one, r100, so only since rv100) had two display controllers. (And it's a very similar story on the green side, every card since GeForce 2 MX / GeForce 4 (not GeForce 3) had two display controllers.)
    That's 8 years now we've been stuck with 2 display controllers (ok there was an even longer time graphic cards only had 1...)

    Ok, lets play along and say its real. Did the rv770 have so many different caches? That digram says it has L2 cache, L1 texture cache, z stencile cache, and color cache. Does that sound right?

    Whenever I read discussions on the different caches on the rv770 I always got the impression they were all read only(true?). Would all these caches still be read only, or is there something in there that says OMG this is totally BS for a gpu?

    There's nothing out of the ordinary. But considering this (rv8xx) is supposed to be a radical change, it seems downright tepid.

    Sounds quite right. I wonder though, apart from 1600SP it would also say 4 quad-rops. I thought "everybody" agreed rops would probably be doubled to 32.

    Based on the interview it's not necessarily "radical change", the "RV770" was mentioned as good starting point, and only one part of the core was specified to be over twice as complex as RV770's, the (main(?)) scheduler.

    It has to be the most radical change since R600. But I'm not sure, who said it - Eric Demers?

    The scheduler could conceptually be in that scheduler block. :???: They are not to scale after all....
