AMD’s Bulldozer And Bobcat Architectures Pave The Way

More On Bobcat

AMD had a bit more to add on its Bobcat design, unquestionably created with the Fusion initiative in mind. The focus here is on Bobcat as a technology, which AMD plans to use to create SoCs targeting specific markets—the first of which should be its Ontario APU, featuring on-die graphics processing, fixed-function video playback acceleration, a DDR3 memory controller, and the dedicated bus linking everything together.

AMD’s estimate here is retention of 90% of today’s mainstream performance (I’d certainly consider something in Athlon II territory reasonable) in less than half of the silicon area. That’s a figure we’ve seen AMD use in past discussions of Bobcat. But perhaps less known was how the company planned to achieve this.

Details being discussed today include a dual-issue x86 decoder and out-of-order execution, perhaps enabling a performance advantage compared to Intel’s Atom CPUs. Bobcat will support SSE, SSE2, and SSE3, along with virtualization acceleration.

Beyond its performance implications, though, AMD repeats over and over that this is a sub-1 W-capable core. Possible though that might be (at standby), remember that Ontario will incorporate a pair of these cores. Additionally, Bobcat is part of a SoC. So, it might be a little more realistic to expect power numbers between 10 and 20 W.

    ok everyone... I swear to god if AMD pulls this one off and bitch slaps Intel again... PARTY AT MY HOUSE!!!

    Really? Here I was thinking that's exactly what AMD was building.

    Thanks for the great article and valuable information. Someone scolded me for saying I wanted to wait for a bulldozer processor to upgrade. Thanks for clearing this up. Yes, Bulldozer is what I'm waiting for, prolly a Zamboni would be nice.
    By the way, just who the hell comes up with these ridiculous names? I personally think manufacturers would sell more units if they weren't so confusing.

    This will help spur a tick or a tock from Intel :)

    dogman_1234No new news here, but I cannot wait until AMD releases "Bulldozer"! The thing that got me was the use of the cores. Really, all AMD needs now is a Commercial. Anybody?

    I'd have to say I partially agree with you. I see way more Intel commercials (many) than AMD (none). My next build: Bulldozer :D

    Not quite, the out of order execution WILL enable a performance advantage compared to Atom, + the added bonus that the AMD GPU on the Ontario platform (if similar or better in performance to the ION) WILL again make for a better platform as a hole.

    On the Bulldozer side, Power Gating and Turbo for modules, TST > SMT should be something to look forward.

    PS: On the commercials side I'm looking forward to something like this:

    Excellent!! i skipped the Istanbul CPU's because i'm waiting to score on a "Scorpius" platform! and i know 100% that i will be able to afford it on release!

    Hopefully, Bulldozer will easily outperform my 955BE. So when the time comes, Bulldozer, Northern islands and about 8GB RAM on a new motherboard. :-) I hope Bulldozer kicks the living daylight out of intel for like one or two generations, so we can get som balance on the market.

    I totaly agree on the commersial bit. :)

    Cannot wait for Zambezi i was thinking of buying a 1095T, now im going to wait and see... C'mon AMD surprise everybody with your new architecture!

    Yeh but Intel also has its new 2011 line-up in the works. I really want AMD to do well but Intel has one hell of a lead in terms of clock-vs-clock performance. But i'm still hopeful...so go AMD!

    AMD had a similar lead before 'core' !

    Thanks for that, I think that clarify's a few things, not fully. But enough for me to make limited sense of it ;)

    To quote another user "the future is AMDeal".

    Intel will need to buy a decent Graphics design team to keep up.

    Goodby NVidia ... your about to be assimilated into the collective.

    Chris, I might have predicted this a few times before ...and got it wrong too.

    Great article btw.

    The main question is, when AMD is saying their 16 "core" processor is 50% faster than their 12 "core" processor, are they saying 16 "real" cores, or eight of these units with two execution engines.

    It's good to see they got away from having ports with both AGUs and ALUs. Hopefully they copied more from Intel than that.

    From this, which i saw a long time ago, so not much new, got me all excited for nothing :( But from this, i dont expect Bulldozer to compete with Sandy Bridge, or the i7. I expect it to be competing with the 980x. Intels charts have that as top dog up until Q3 2011. Therefore, we can guess SB will be more on a middle range. Bulldozer on the other hand, more specifically Scorpius, will be AMD's highest performing chips. Id expect them to take on the 980x, not really intels lower end. Some other chips will be made to do that. And to be honest, I think AMD has a winner :)

    From the looks of it Zambezi sounds like it would outperform the i7 920 if it just used 4 cores except that it will have 8 cores (4 modules).It looks like it might even match or maybe outperform the 6 core i7-980X Gulftown monster.That is if AMD can really execute this properly.
    Will Intel have faster CPU's by then? Probably.
    The real question is will software catch up with this new hardware?
    PC Gaming will be great really great with high FPS with new GPU's
