Rumor mill details hot-clocked Zambezi quad, Llano duallies

As the world waits patiently for official word on AMD’s upcoming Bulldozer-based Zambezi processors, the rumor mill continues to churn out information on the chips. The latest comes from Turkish site Donanim Haber, which has posted a couple of presentation graphics that don’t look like they’ve been cobbled together in Photoshop by a bored teenager.

Much of the information in the graphics is old news. However, there appear to have been changes to the FX-4120, a quad-core model that earlier rumors suggested would debut in 2012 with a 95W thermal envelope. Now, that chip is expected to show up with the initial batch of FX processors, and the TDP has purportedly been raised to 125W.

The FX-4120 should be the highest-clocked member of the Zambezi family. The chip will reportedly have a 4.2GHz base clock speed with a 4.3GHz Turbo peak. The flagship FX-8150, which has twice the number of cores, is supposed to run at 3.6GHz with a 4.2GHz Turbo ceiling. Thanks to its higher clock speeds, the FX-4120 may deliver better gaming performance than the 8150, which would be one reason to bring it out early. The small 100MHz gap between the CPU’s base and Turbo clock speeds make me a little dubious about the veracity of the leaked specifications, though. The 4120 doesn’t appear on the list of FX processors leaked last week in a Gigabyte motherboard compatibility document, either.

If Llano is more your speed, Donanim Haber has what looks like new information on A4-series APUs destined for desktops. According to the site, the A4-3400 and 3300 are both due out before the end of the year. These duallies will run their cores at 2.7 and 2.5GHz, respectively, and they’ll both carry 65W thermal ratings. I’d expect these chips to be based on the current quad-core Llano silicon as opposed to the native dual-core die, which seems likely to populate notebooks before migrating to the desktop.

    Bulldozer delayed again

    [url<][/url<] Probably not last time... Update: They want to speed up that CPU, and rename it to Bulldozer E !!! 🙂

        AMD is praying the Mayan calendar is for real. If they can only hold the launch till the world ends, they won’t have to live the the shame anymore.

      Ouch… and it looks like the October launch won’t even be a hard launch. At this rate, the first gen Bulldozers won’t be widely available on Newegg until around the same time Sandy Bridge E shows up (assuming Intel doesn’t delay it further too).

      Desktop Bulldozers may be delayed, but apparently Interlagos is shipping to OEMs now:

    A4-3400 is already in stores in Europe and Asia.

    Was hoping flagship Zambezi was going to be ~3.8 :/

      That makes no sense. Why would you rather it ran at a higher frequency for no reason? If it’s competitive with Intel at 3.6 then that’s what it should run at, and not at 3.8 for the sake of running at 3.8. Besides the Turbo is going to go up to 4.2, which means it’s capable of running at higher frequencies. There’s absolutely no reason to make it run higher at stock.

      They should leave themselves headroom for improving the lineup and increasing freq. gradually, not paper launching a high frequency model that has extremely limited availability and only top enthusiasts line up for.

        [quote<]That makes no sense. Why would you rather it ran at a higher frequency for no reason?[/quote<] How ironic that you would say StuG makes no sense... Having 3.6GHz as stock frequency instead of 3.8GHz at 125W TDP implies the chip isn't as efficient as StuG hoped. What's your problem with this?

        Maybe he’s an Intel fan and wants it to be slower?

    • sweatshopking

    wow. amd, wtf? 4.2 to 4.3? why even bother?

      • UberGerbil
      • 8 years ago

      Maybe that 3 is actually an 8? It’s all rumors at this point, and not all of them pass the smell test.

      (I wouldn’t be surprised if one of the defining characteristics of the FX models vs non-FX wasn’t a markedly higher turbo peak, but rather how many cores/modules could be at that peak simultaneously)

      • NeelyCam
      • 8 years ago

      If you can, why not?

      To me it seems that 4.3GHz is the peak frequency that the chip can run (logic speed-path limited), while the thermal limit (125W) for a frequency of a quad-core is 4.2GHz (and for an octa-core it’s 3.6GHz). And if you can turbo to be a bit faster, no reason not to do it.

      Yeah, kinda like Ferrari’s upper-rpm exhaust bypass that bumps redline from 7900 to 8250….

    If I had a dollar for every BD rumor that comes out from DH…

    Ahem.. Anyway..

    4.2GHz base clock and 4.3GHz Turbo? A 2.4% increase? Seriously? Why bother?

    If this quad can outclass a Core i5 2500 or even an i7 with a roughly similar power envelope, then it’s time to get up and clap your hands. If it doesn’t, time for AMD to price it a tad lower than those Intel parts so we get to save a bit of cash.

    As for the A4… Zzzz….

      If only I had a dollar for every AMD rumor from DH that turned out to be true..

        You could buy lunch with that kind of cash!

          …at a very cheap place.
