    Hi All,

    Not sure if I can raise this here or not, Still I will raise my Question

    Now a days, there are lot of Laptops in the market are available with Intel
    Core Duo microprocessors. Are these Intel Core Duo is same as Intel Dual Core?

    When I am searching in Web, I found an article in which it specifies Intel
    Core Duo is different from Intel Dual Core. Specs are as follows:

    Intel Core
    • Introduced January 2006
    • Yonah 0.065 μm (65 nm) process technology
    • 667 Mhz frontside bus
    • 2 MiB (Shared on Duo) L2 cache
    • Variants:
    o Intel Core Duo T2600 2.16 GHz
    o Intel Core Duo T2500 2.00 GHz
    o Intel Core Duo T2400 1.83 GHz
    o Intel Core Duo T2300 1.66 GHz
    o Intel Core Solo T1300 1.66 GHz
    o Intel Core Solo T1200 1.50 GHz [1]

    Pentium D (Which is a Dual Core processor)

    • Dual-core microprocessor
    • No Hyper-Threading
    • 800(4x200) MHz front side bus
    • Introduced May 26, 2005
    • 2.8–3.4 GHz (model numbers 820-840)
    • 90 nm process technology
    • 1 MiB x 2 (non-shared, 2 MiB total) L2 cache
    • Cache coherency between cores requires communication over the FSB
    • Performance increase of 60% over similarly clocked Prescott
    • 2.66 GHz (533 MHz FSB) Pentium D 805 introduced December 2005
    • Introduced January 16, 2006
    • 2.8–3.6 GHz (model numbers 920-960)
    • 65 nm process technology
    • 2 MiB x 2 (non-shared, 4 MiB total) L2 cache

    Can any one suggest me which is which?

    Thanks in Advance

  3. The way I understand it (but as always, I could be wrong!):

    Core Duo is a single processor that supports multithreading in an efficient

    Core 2 Duo is two separate processors on a single chip.

    Duo is simply a trademarked name.

    Hmm, Wow Mark & Alen,

    Your comments raised confusion once again.

    Any More Help Please

    Thank you,

  5. How about this: All "Dual Core" Pentium Processors have two processors
    embedded on the chip, but not all "Core Duo" processors are "Dual Core."

    It's Intel's way of keeping people confused, I believe.

    My Goodness, Thank you Mark.

    This is unbeleavable. This is real confusion from INTEL.

    I wonder, if any one buying Dell Laptop's know about this. Dell always
    selling INTEL CORE DUO .


    I wonder if there is any good supporting document about this.

    Thank you Mark & Alan

  8. Core Solo is single core.

    All Core Duo and Core Duo 2 chips are dual core.

    Core Duo is 32bit and Core Duo 2 is 64bit.

    All Core cpu's support Virtualization Technology in hardware.

    A 64bit dual core running a 64 bit OS- that's the shite!

    The Core Due had been getting good press.

    Of course, the Quad Core (Clovertown) will be out before you know it.
    Time flies by; and so does technology. A quad core will make into consumer
    computers before you know it.

  10. I think it's "Core 2 Duo" and not "Core Duo 2", unless we are talking
    about two different things.

    Also, "Core 2 Duo" isn't out yet. The desktop Core 2 Duo CPU comes out
    this Sunday, July 23rd (Intel does their releases and price changes
    officially on Sundays, not sure why). That is the processor that has
    been known as "Conroe".

    The date on the mobile version seems indefinite, but it's coming in the
    next 60 days. That is the CPU known as "Merom".

    Both were developed by Intel in Israel.

  11. Core Duo 2 should be getting good press. Especially with the reduction of
    heat dissipation! I have been running Vista x64 on a dual core system for a
    year now. The impression for me is silkiness.

    According to the specs, Core Duo is dual core:

    "Intel Core Duo consists of two cores, a 2mb L2 cache shared by both cores,
    and an arbiter bus that controls both L2 cache and FSB access. Upcoming
    steppings of Core Duo processors will also include the ability to disable
    one core to conserve power."

  13. It is the only 32bit dual core processor I have seen. It is fast and it
    does support VT so I use it for virtual machine work.

    Colin Barnhorst, Jul 19, 2006
  14. Maybe that's why Intel is having a layoff.

    In a pinch, you could always go to and choose Products >
    Processors and find out.

  16. Well, yes all Core Duo are dual core, but there is a Core Solo, so not all
    Core processors are dual core. Core is a new line of processors that have
    more efficient messaging in the unit.

    The latest information I heard is: July 23 for mobile version (Merom), July
    27 for Extreme edition of Core 2 Duo, and the rest of the Core 2 Duo line-up
    is out now, though may be hard to find.

    Gary Mount, Jul 19, 2006
  18. I don't think that ANY of the Core 2 Duo line is out as of today; I
    believe that July 23rd was the official release date for the entire
    line, except possibly for the Extreme Edition (not that the difference
    between July 23rd and "today" matters much at this point).

    The bigger problem is that very few motherboards are available. Several
    are announced, but very few are really available.

    Core 2 Duo is the new upcoming (last days of July 06) processors based
    on the new Intel core technology. All of them will be dual core ( two
    cores on the same chip) and enhanced power efficiency, to be used on
    laptops and desktops.

    Core Duo are the current core technology, which Core 2 Duo replaces.
    it's a dual core processor optimized for power efficiency used at
    laptops mainly.

    Pentium D is the dual core version of the Pentium 4

  20. Yup. Wrong again! You'd think I would learn...
