    Yep.Actually that list of uarch changes BD-PD is more significant than previous info.. could be looking at >5% avg IPC boost out of those, I'm guessing with those apps that suffered most with BD uarch getting a good boost.

    especially given the current IPC is off target quite a bit (target was to hold IPC steady with K10, reality is it averages ~15% lower )

    well it looks like the chef architect of bulldozer has died, RIP

    Browsing the Open Compute Project I came across their AMD Motherboard RoadRunner (Specifications), and under section 5.3, "CPU and Memory" we see:
    which in and of itself isn't anything we couldn't have guessed from what leaks we knew, but it's nice to see it written in an official document.

    I thought this was interesting (from section 5 "Motherboard Features", under "Processor":
    So it sounds like Piledriver is thought of as Orochi revision C, with revision A never making it to market (the leaks being that it was more akin to a man with a shovel than a bulldozer) and revision B being what we have now with Interlagos/Zambezi. If all of the improvements and advancements that we saw in the slides leaked last week come to being then that's pretty good for a Rev-B to Rev-C change...

    Oh, and in case you're wondering, the document should be accurate - all three authors are from AMD, and two are:
    Bob Ogrey: Cloud Technical Evangelist Fellow Server Platform Architecture
    Eugene Chung: Manager Systems Design Engineering at Advanced Micro Devices

    In any case, the document is an interesting read. The system configuration aimed for Storage looks nice :thumbup:

    Hopefully they can hit their release scheudles and maintain momentum.

    I'm quite surprised that they are aiming to push piledriver out so early, I was expecting a November-janurary release. I really hope they aren't compromising too much development to release it so early, not that we're expecting much but some tweaks to wring out more performance per clock would be nice (and are needed).

    It'll be much easier for AMD to release Trinity than it was for BD.
    BD was a completely new architecture on a new process node. Trinity is a tweaked BD on the same process node.

    I would hope BD -> Trinity is analogous to Windows Vista -> Windows 7 (Vista being written basically from scratch and having a lot of bugs, and Windows 7 being a fixed and properly done Vista.)

    On piledriver.... did I read correctly in here somewhere that it will be coming out in 8, 12 and 16 core variants?

    Most of the revisions to bulldozer that make up 'piledriver' where in the pipeline well before BD eventually went on sale last year. The problems where known from the first few batches of eng. samples and any information gleaned from those dies would have gone straight into the new Trinity.

    Given how aggressively AMD is pushing APU's this really is no surprise.

    The ten core Piledrive or Vishera was canned shortly after AMD named a new CEO.

    The 16 core version could possible be referring to two 8 core dies in a single package (didn't AMD do that with magny cores? two six core dies in a single package for a 12 core single socket?)

    AMD Interlagos server CPUs are already 16 cores based on 2 x 6 core in a single socket.

    At AMD Fusion Developer Summit 2011, a couple of hours after announcing Llano APU to the world; they demonstrated Trinity APU in working silicon and running on a notebook reference platform.
    => http://www.youtube.com/watch?v=dJePRtcKLHs

    ...So they have been working on Trinity for quite a while.


    It shouldn't be too surprising as they're focusing on releasing a new APU every year. The annoying part is likely to be that they keep changing processor sockets during the early years of their APU-era.

    Was probably referring to two die, 16 thread, interlagos parts.


    https://en.wikipedia.org/wiki/Opteron <-- they are listed here at the bottom.

    Haha yeah, that would be 2 x 8=16 ( I checked with my calculator!)

    AMD readies R-series embedded APUs
    => http://www.cpu-world.com/news_2012/2012051001_AMD_readies_R-series_embedded_APUs.html
    (There's a graph from AMD showing how much their IGP is better.)

    These are just embedded versions of the upcoming Trinity APU line.



    A reminder of the AMD APU lines...

    Z-series = Tablet or Fanless platforms. (4.5W to 6W)
    C-series = Consumer netbook/nettop/low-power computing. (9W class)
    E-series = Consumer netbook/nettop/budget computing. (18W class)
    G-series = Embedded versions of C-series and E-series.
    A-series = Mainstream consumer desktop and notebook.
    R-series = Embedded version of A-series. (Similar to notebook version).

    Slight blur in between A-series and E-series...
    Brazos 2.0 based => E1-1200 and E2-1800 models.
    Llano based => E2-3200 model.


    May 15th is what I hear on the announcement of the notebook version of Trinity APU.

    Nice. Any word of FM2 motherboards?
