    Well, it's the only mysterious Intel architecture

    2011 <--> 2013 "Haswell"

    AVX, XOP, FMA4 <----> AVX, AVX2, FMA3

    I can only guess in 2013 Next Generation Bulldozer

    2013 <--> 2015 "Skylake"

    AVX, AVX2, XOP, FMA4, FMA3 <--> AVX, AVX2, AVX3?, FMA3 and maybe FMA4

    Only if FMA3 is better

    Bulldozer tends to be a tinny bit ahead, with XOP and AVX with FMA4(which allows 2x the performance(XOP and AVX2 allows FMA3 and FMA4 on "IMACs")

    Maybe I should have pointed out I am talking about ISAs again(My workloads are heavily dependent on ISAs)

    Your point? It's one thing to have an instruction set, quite another to judge performance based on what the instruction set of a CPU looks like.

    Only a tiny fraction of software use IA-SSE4. That isn't what's responsible for Penryn, Nehalem, Westmere, and Sandy Bridge being faster than K10.

    why don't we all just cool off for the moment, come back when there are some reviews after the almost certain paper launch b4 September/ Sept 9? (according to seronx) and the likely hard launch on Sept 19th. the only people who are going to know anything b4 then are reviewers and that will only be a couple days b4 launch.
    I just want AMD back in the race... if somehow bulldozer can give sandybridge a run for it's money i'll be happy.

    What btarunr is trying to say is that if you base the performance on some charts, diagrams and slides you can have the best CPU out there.
    But the actual product is another thing.

    If I would only look at the slides for Phenom I could say It would destroy everything, but we know what happened with the actual product.
    Same could be said for P4, it looks good on paper but in reality it's only a room heater.

    You can't say anything just by going with stuff on paper.

    Oh boy. Everytime I see a Bulldozer thread it's like I keep having deja vu..

    We should know more about Bulldozer when they paper launch. Until it's properly launched, tested, and reviewed, keep all your "opinions" to yourselves. Because they are ALL opinions until we hear an official statement from AMD, nothing more. So we can all speculate till our pretty little heads explode, but I for 1 will believe performance numbers when the fat lady sings.

    Bulldozer retires max 4 macro ops + 1 if branch fusion(I have no idea....)

    So, 4 in most max cases, 5 in rare max cases

    The "BD" Core Scheduler receives/dispatches/and retires? 320bits 5(x86-64) "64bit" Cops/5(x86)-10(x86-64) "32bit" Sops <--- Maxes

    The only issue with this the core 2 ALU+2 AGLU, compared to Intel Sandy Bridge it is missing only an "Add" ALU(Sandy Bridge has 3 ALU + 2 AGU + 1 Store/Load(The equivalent to the LCS in Bulldozer)

    [​IMG]

    But based on this it is irrelevant

    There are other things that supposedly improve performance but the main point is "Bulldozer" can feed the cores and all components are most likely going to get stressed

    So, on the core side

    AMD has 2 64bit ALU+2 64bit AGUs+1 Store/Load and now you have to include the floating coprocessor unit which schedules from one core but can execute two cores


    AMD "Bulldozer" FX
    (2 64bit INT ALUs + 2 64bit AGUs) x 2
    +
    (2 128bit FP ALUs + 2 128bit INT ALUs)
    +
    (128bit Store/256bit Load Cache Units) x 3 (1 in each of the cores 1 in the floating point unit)

    vs

    Intel "Sandy Bridge" i7
    (3 256bit FP+INT ALUs + 2 64bit AGUs + 1 Store/Load)

    That's not true either. Closer to six months than a full year. ^^

    All i know is BD will be the only plausible long term upgrade route for this hardware junkie. I stopped benching and don't care for numbers anymore. Found an upgrade path that suites me and that is am3+. I still got Thuban and Zambezi i can upgrade to from my unlocked dual. I'm happy. :toast: and please don't flame war each other. I want to learn something with some current info that IS available.

    Omega does the CPU benchmarks

    and I wouldn't really trust Techpowerup reviews either(they are usually highly biased), I am here for the community

    Core vs core intel are still going to be on top, but AMD is going down the road of packing as many cores in as possible.

    AMD have chosen to have most of the performance of a extra core without building an extra core ( meaning more space available or cost savings)

    So just bare that in mind folks.

    If they do manage to keep up core for core then AMD are magic.

    Not being fanboy-ish, why are you bringing intel into this conversation? I thought this was supposed to be Bulldozer info thread? :eek: I'm waiting for more info if available! :eek:

    Well seeing as theres only really two choices for my CPU the companies kinda go hand in hand :toast:;)

    I just hope Bulldozer is at least as competitive as the i5's otherwise AMD is headed the way of the dinosaurs and fast...

    That made my day:laugh:

    I believe AMD is as aware of this fact as everyone else, so I highly doubt it will disappoint:)
