    Hi guys. I've been using my trusty i7 2600k and GTX 580 for a year, but Bulldozer is coming, and it looks incredible.

    So I might upgrade to Bulldozer in a couple years, when "Next Generation Bulldozer" is released (source:wikipedia). So I just wanted to know - what do you think about Bulldozer? I upgrade every three years.

    bulldozer won't be even close to a 2600k, check back for new intel cpus in 2013. ivy bridge is just a 22 nm shrink of sandy bridge, so not worth it if you already have a 2600k

    Do you know what kind of performance increases we'll see from Ivy Bridge?

    smaller die size, less heat output, slightly higher clock speed, nothing significant

    lga2011 with x79 might be interesting, but it'll only be a minor upgrade for you.

    Most likely out perform Intel options till Skylake

    Bulldozer generations ahead of Intel

    AS far as i remeber none of us still know the true speed of bulldozer, Yes we have seen lots of pics and info but is any of it real concrete evidence? Lets just wait and see.

    Bulldozer is a interesting architecture which many people are confused on...

    Alot of people say it will increase multithreaded performance but that is indeed wrong as when both cores are used in a module the effective clock is halved(Reverse of Netburst, where Netburst had a double effective clock Bulldozer has a half effective clock)

    To make up for this performance drop they increased the cores performance to some degree

    Wait for reviews AlphaStormX, supposed to be coming out September 19th 2011 hopefully but you seriously don't need to upgrade man, 2600K + GTX 580 = Epic system anyways:toast:

    Well 2600K depends on the workloads

    There are some workloads that are better than others

    So, because I forgot to ask this AlphaStormX what are your workloads?
    ----
    The supposed release is actually next week(Paper or Real Launch place your bets!)

    [​IMG]

    But, the supposed press NDA doesn't end till September 6th <-- this number was shot out in July 5th and, it has been almost 2 months
    Lionheart says thanks.

    I think ivy bridge is supposed to have the new 3d transistors? Correct me if i am wrong.

    Doubt it. If AMD had a rabbit in a hat, they'd have pulled it out by now. All the moves AMD is making (without the MCM rabble) are identical to the disappointing Phenom release. They're going for price competitiveness over performance competitiveness.

    [​IMG] <-- this is Intel's FD-SOI

    It's unknown if AMD will ever use their 22nm FD-SOI

    http://www.internetnews.com/infra/article.php/3080111/AMD Joins TripleGate Race.htm

    http://www.bit-tech.net/news/hardware/2011/07/12/global-foundries-tri-gate-competitor/1

    but AMD tends to have a track record when jumping to "New" architectures they have an equivalent Fab node process to the "tick" of Intel cycle

    Core 2 65nm -> Agena 65nm -> Nehalem 45nm -> Deneb 45nm -> Sandy Bridge 32nm -> Orochi 32nm -> Haswell 22nm -> Next-Gen Bulldozer CPU Die on 22nm?

    yes, but (simplified) all it does is let you run higher clock speed at same voltage and power.
    so you can either reduce power & heat or increase clocks at same power or a mix of both.

    they also occupy less die area which can help with cost savings

    So ideally, Intel could pack even more tranzistors in the same die area, not just becouse of the 22nm fab process, but also becouse of the 3d transistors?

    3d transistors are kind of a way to get to 22 nm for intel.

    remember back when we couldnt scale up mhz anymore? but we still wanted faster processors, so the engineers invented multi-core processors. to me it seems like this 3d transistor thing is similar

    I don't know where you got your facts from, but it's far from plausible.

    Tri-gate FD-SOI designs don't technically increase the transistor count but increase the effectiveness of the transistors

    The problems with these designs are

    -Power
    -Heat
    -Cost

    Power Consumption can rise dramatically(If voltages stay the same)

    Heat can rise dramatically(<-- unsure about this one, I might have gotten in backwards(It might lower))

    Cost can rise dramatically(More steps in the fabrication process, requires a delicate touch)

    For example a mature 45nm fab process and a mature cpu architecture that is 349mm^2 might only cost a certain CPU company $50-100 per yield
    Moving to a new CPU Architecture and a new 32nm fab process with a smaller die size 315~mm^2 might cost between $105-160 per yield
    Then moving that architecture with a couple difference to 22nm with a slightly small die size 265~mm^2 might cost $180-$250 per yield

    How so, Sir Btarunr?

    This:
    ...is far from 'fact', and lightyears away from plausible.
