Basing your prediction of a major improvement on a single data point when the last few before it didn't pan out the same way is being hopeful, not logical. Also keep in mind that I'm only talking about shrinks of an existing architecture and that I'm only commenting on node performance at introduction. AMD's processes always mature nicely. They just usually suffer a rocky start.

    Particle's First Rule of Online Technical Discussion:
    As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.

    Rule 1A:
    Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.

    Rule 2:
    When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.

    Rule 2A:
    When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.

    Rule 3:
    When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.

    Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!

    Random Tip o' the Whatever
    You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.

    Thats what I'm saying.

    Their maximum on 65nm was about 2.6-2.7 Ghz if they were to push frequencies and on 45nm the same core made it all the way to 3.7 Ghz.

    To have the same freq. scaling they would need to start out with a 3.7 Ghz chip. Not that it matters with a different architecture...
    Beep I know what you try to say, but AMD's 65nm process was bad, therefore it is bad to reference to it and extrapolate process improvements between nodes. On another hand 32nm process introduces Gate First and HKMG which somewhat balances things out. I doubt though it balances things enough for basing any clock improvement extrapolating AMD's 65nm->45nm transition. Besides we initially had 2.6GHz Agena to 3.0GHz Deneb! The difference you're referring to is for both mature processes. When BD launches 32nm SOI won't be mature enough to fully extract available performance. I expect close to 5GHz stable OC from BD style design on fully mature 32nm process after 2-3 design revisions. Initially I'm hoping to be able to clock 1 core towards 4.8-5GHz stable. All 8 cores @4.4GHz would be sweet for me as well. On air that is

    Bulldozer ES vs Core i7-990X gaming showdown

    CPUs overclocked to 4 GHz, SLI Nvidia GTX 580

    Have a look here, it is at the bottom of that page: http://pctuning.tyden.cz/hardware/za...-zari?start=11

    Don't speak Czech or Google translate too gritty? Look here: http://www.maltrabob.com/BDvi7.html

    Considering that we are still talking about engineering sample, the results are not bad at all in my opinion.

    I wonder how many cores do those games use, if only use less than quad core then it's a good sign, because bulldozer module is not true dual core but somewhat weaker dual core, take the crappy ES bug especially frequency problem into account then Zambezi looks optimistic.

    Ive got a feeling those games are gpu limited at these settings.Anyone has GTX 580 SLI to do a compare ?

    Yes, but the ones above ~150 fps really start to show a difference.

    AGAIN, OBR posted a Cinebench 11.5 stable screen at 4.67 Ghz. That thing has a GPU on the die...
    If it were stars alone on AM3+ I'd expect up close to 4.8 Ghz with some chips. Add four more cores? Okay, lets go with 4.6.

    Because they are clocked a lot lower

    Wouldn't this be enough to indicate it's likely not a 'Dozer chip?


    1.4750V default, 2.0750 overvolted?


    EDIT: Nevermind, I see what he did. Was showing max voltage for each. I'm going to assume that 1.4750 is also just the ES chip pre-set voltage to make sure it's stable. At least, I'm hoping that's the case.

    The NDA is under NDA. Good luck getting any information from AMD.
    As quoted by LowRun......"So, we are one week past AMD's worst case scenario for BD's availability but they don't feel like communicating about the delay, I suppose AMD must be removed from the reliable sources list for AMD's products launch dates"

    I give up.

    If Stars is "greater than 6%" better than previous stars, I'd expect at least 15-20% from Bulldozer would I not? Otherwise, Trinity would be a total waste of time in using Bulldozer cores for a measly 4% increase (if it were 10% faster) to be made up by 100 Mhz in clock. Not to mention Llano is L3 free, who knows what performance benefits that core would have with L3? 10%? ...oh wait, I'm not supposed to be logical.

    Tin hats.

    Time to talk about some funnier stuff.

    I took the time to modify some funny chops people did in another thread into a short narrative.

    Would it be over optimistic to think maybe Intels spys in AMD have bought back some info on BD performance so revisions are needed by intel so in Jan they can regain the crown that BD may take when it comes out? Any way, where are the lines drawn between hopeful > optimistic > over optimistic
