Difference between Intel’s Core 2 Duo and Dual Core processors

This seems to be the confusion of many people today and most of them don’t actually know the difference between Intel’s Core 2 Duo, Dual Core, Core Duo and also Pentium D processors.

Let’s see the differences between them:

In a simple language, all these processors listed above are Dual Core processors in general.

•    The processor Pentium D is just the two Pentium 4 Prescott processors inefficiently paired together that run as a dual core.

•    Core Duo is a first generation dual core processor from Intel that is based on the Pentium M processor and is mostly made for laptops. This is a much better processor than Pentium D processors and is a 32-bit processor.

•    Core 2 Duo is Intel’s second generation processor and is made for both Laptops and Desktops. This is a fast processor that consumes the minimum power as compared to the above CPUs. It is a 64-bit processor.

•    Dual Core is nothing but a term referring to a processor package with two physical processors in one.
The other big difference among them is based on Cache memory.

While the Dual Core has a dedicated cache memory, the Core 2 Duo has a shared one. Thus Dual Core is generally better.

  1. Hi,

    I have read the below topic of ‘difference between dual core and core2duo’. Last sentence you have mentioned that “While the Dual Core has a dedicated cache memory, the Core 2 Duo has a shared one. Thus Dual Core is generally better.” I don’t think so it is not correct as per my knowledge the main difference is mentioned below.

    In Dual core both the cores share same cache memory
    In core2Duo both the cores have separate cache memory

    Thanks

  2. Hi to all,

    As per Aneesh analysis its right … main difference between core2duo and dualcore is its catch only … Dualcore is not at all better than core2 duo ………

    Example: Having 2 house always better than one house
