Intel’s new Core Microarchitecture promises to increase performance and cut power consumption

“With energy efficiency creeping up enterprises’ evaluation criteria list, Intel knew it couldn’t afford to allow its future chips to use more power. The Santa Clara, Calif., company went back to the drawing board to create a new chip architecture—a replacement for the circuitry that underpins its entire x86 product line—that would both increase performance and cut power consumption,” John G. Spooner writes for eWeek. “Intel will roll out three dual-core chips based on the new Intel Core Microarchitecture later this year… One major change along these lines was the addition of the ability to execute four instructions in a single clock cycle.”

“Intel also chose to use a 14-stage pipeline, and designers cut onboard cache access times and beefed up the ways in which data is prefetched from system memory to ensure that processor cores aren’t kept waiting… The 14-stage pipeline is slightly longer than the ‘Banias’ architecture behind the company’s Core Duo notebook chip, which has 12 stages. But it’s still about half the length of later Pentium 4 processors, which process only between one and three instructions per clock cycle,” Spooner reports. “The new architecture will allow chips such as Intel’s dual-core ‘Woodcrest’ server processor, due in the third quarter, to offer a 35 percent reduction in power consumption with an 80 percent bump in performance over the current Xeon DP processor.”

  1. While it’s nice that Apple seems to be trying to play catchup, ultimately none of this will matter. The Next Step in Trusted Computing, Microsoft Windows Vista, along with .NET, will provide an all-encompassing solution for personal and business applications.


  2. And when is this “all-encompassing solution for personal and business applications” coming? 2007? 2008? Or have you been taken in with Microcraps new advertising thing, People Software.

    Sputnik, go crawl back to where you came from.

  3. Sputnik! Almost missed having you around.
    But really, your material; if it’s straight or shtick, it’s last year’s model. Even the Big M$ knows that VISTA & .NET are “beleaguered”.
    Time to refresh it. You can do it!

  4. Fewer pipeline stages is great news. If I remember correctly, the G4 had 7 stages. I don’t know how many the G5 has but I’d imagine it’s around there somewhere. That should please people who were worried about leaving the efficient PowerPC chip to go to a less efficient x86 chip. As I’ve said before, these are not your father’s x86 chips. If Intel was still traveling down the 22+ stage Pentium road, I doubt Apple would have switched.

  5. By the time I am ready to replace my powerbook with a new Macbook pro they will have some really sweet battery results and be so fast, but until then I am sticking with my powerbook. Gotta finish my payments on the damn thing.

  6. Sputnik and I enjoy playing the devils advocate occassionally.

    Some of your responses and mimicks are just hillaious.

    And yes some people actually take what we say seriously, like what I or Sputnik says will actually change the course of the buying public with all those Apple Stores?

    To those I say:

    Apple is already dead, just a few more nails in the coffin and they will be done.

    Hail Vista, whenever it arrives.

  7. I’m going to tell you something about what Intel is up too.

    You see, the physical limitations of size and processor speed has been reached, they can’t get them much any smaller or faster, that’s why they are adding cores to processors instead.

    Now they are trying to optimize the power consumption and other things to squeeze out a little more performance. But it’s really trying to find a few more drops out a already squeezed lemon.

    What’s needed is a whole new concept with processors and IBM had the answer with the Cell processor.

    However Apple and Steve jobs couldn’t take such a leap because Apple is trying to gain market share and you just can’t jump off on such a wild new processor design and expect to turn a profit.

    So Steve Jobs chose Intel, for good or bad, because both PC’s and Mac’s will be in the same boat and Apple can compete on software as the hardware requirements are the same.

    Since Apple is a consumer company, it doesn’t pay to go off on a wild new processor design because only buisnesses will invest it it, not consumers who need compatability with the zillions of x86 software developers.

    The Cell processor could have been a really wild thing, we would have computers immensly powerful, but most users don’t even have a need for 64 bit.

    Web, email, Office, some games, some music.

    That’s mostly all consumers want or need.

    I got a Dual 2 Ghz G5 and it’s 10x more power than I need most of the time.

    Since buisnesses won’t buy Apple computers, it doesn’t make any sense to make a really powerful Cell based Mac for them anyway.

    IBM would just muscle in anyway.

    So for some really cool 3D animation workstations based upon the Cell processor, I guess we will be looking at some other comapny.

    Apple should invade this space with their software knowledge can make a tidy profit in this small niche.

  8. Macdude:

    It is obvious to me now. Yours and Sputnik’s talents, insights, and intellects are needed elsewhere, where enterprise and academia, politics and cultures converge and fuse into a munificent energy source of transcendental proportions. Here great good for all of humanity could be accomplished. In fact, I believe that if each of you consummates an alliance this union will usher in a new and blissful millennium. No natural force on this planet can prevent Macdude (Exponential Man) and his trusty sidekick, Sputnik (Wonder Boy)!
