Intel preps 6-core Xeon ‘Dunnington’ processors

“Late last month in Austria, Intel presented Sun with roadmaps discussing details of its upcoming server platforms, including the fairly secret Xeon Dunnington and Nehalem architectures. Unfortunately for some, this presentation ended up on Sun’s public web server over the weekend,” Kristopher Kubicki reports for Daily Tech.

“Dunnington, Intel’s 45nm six-core Xeon processor from the Penryn family, will succeed the Xeon Tigerton processor. Whereas Tigerton is essentially two 65nm Core 2 Duo processors fused on one package, Dunnington will be Intel’s first Core 2 Duo processor with three dual-core banks,” Kubicki reports. “Dunnington includes 16MB of L3 cache shared by all six processors.”

“Intel’s slide claims this processor will launch in the second half of 2008 — a figure consistent with previous roadmaps from the company,” Kubicki reports.

  1. With core count and memory sizes starting to increase fairly smartly, does anyone know how well 64 bit Vista scales to utilize them? I would expect the UNIX based OS X system to have a distinct edge in scaling performance over the Windows system, but have no information to support this. I’m wondering where the point of diminishing returns is for Vista and OS X, and am thinking that OS X may have a good message here. Of course how well the applications can make use of multiple cores is a whole other topic.

  2. uh“, you are both right and wrong. “Most” software is designed to use a single core – end of story. But … “most” software was either designed a couple of years back or really can’t benefit significantly from multiple cores, or threads, or whatever. Much of the newer software – especially from Apple, itself – that can benefit from multiples is designed to take advantage of what’s available. Logic and Final Cut, for example. No real point in multi-threading Solitaire ’till Dawn, is there? Pages, on the other hand …

  3. Having said the above, I have multiple single-core instances of Folding@Home running on my Dual G5 and would love to get a Quad (or Dual Quad?) to run a couple more. As it is, I lose a third of my cycles on each when running WoW. That is one of the “problems” with taking advantage of multiples. A Quad (or better) would allow me both to run an additional instance of this important software AND play WoW without cutting back on the cycles devoted to F@H.

  4. Two of those would make an even dozen.

    And you could use just one for a six-pack iMac.

    Seriously, I think Mac OS XI (eleven) will mark the milestone of software that can actually take advantage of all those cores in everyday use. Meanwhile, the Windows crowd will be getting Windows XP SP4 (aka Windows 7).

  5. I see the Steve hasn’t gotten Intel to use Keynote yet. Man, those were some ugly a$$ charts. Almost as frightening as Obama, Clinton or McCain as President.

    Intel’s screwed. The Amercian people are screwed. What next?

    THE ENTIRE WORLD WILL NEED GLASSES JUST LIKE ME!!!

    MUHAHALALLAALA!! – Steve Jobs

    Psst: piratebay – requiem-1.0 – transmission – unlock iTMS DRM – hurry!! Limited time offer!!

  7. Ok. Am I missing something here?

    The MacPro has 2 x Quad processors. 8-core machine.

    That’s 2 MAIN chips inside and each CPU has 4 processors combined on one die. AM I RIGHT?

    SO now – what is being offered here… by Intel to Sun.
    What is a 6-core machine then and why less?

    It would sound better if it were 4 x Quad processors.
    OR 8 x Dual processors – COME ON now!

    3 x 2 Dual ? Uhhhhh

    Good that they are pitching SUN!!!!
