  1. Dual Core vs Core 2 Duo
    Dual core processors are those that contain 2 cores in a single silicon chip while Core 2 Duo is the name given by Intel to its second batch of dual core processors.

    Two or more cores can greatly aid in multi-tasking where each core can work independently of each other. All processors that have 2 cores in them are collectively called as dual core processors regardless of which manufacturer it came from, while those that have 4 processors in a single chip are called quad core.
    Initially, Intel called their dual core processors as Core Duo, a very obvious reference to two cores, while AMD called theirs the X2. Intel’s dual core processors were simply 2 Pentium 3 processors that were fabricated in a single chip. As they refined their product more, they decided to differentiate their second set of processors from the Core Duo and decided to call it Core 2 Duo.

    Intel Dual Core is the first dual-core CPU from Intel. The Dual core makes use of two cores on a single die i.e it has two chips in one package. It solves the problem of overheating of Intel Pentium D without compromising on the performance.

    Intel Core 2 Duo processors are the next gen processors from Intel. It is developed with a new Architecture called Core. The new architecture of Intel core2 duo makes it a lot better processor that runs cool. Most importantly the Intel core2 duo is a super over clocker.
