Core2Duo Vs Dual Core

Post by Face » Tue Apr 06, 2010 6:04 pm

core2due & dual core

We know that core 2 due processor is good than dual core..In our computer shops we see the big gap of the prices of these two processors.Dual core is cheaper than Core2due..

What is the technology deference between these two processors??

The Pentium D is simply two Pentium 4 Prescott CPUs inefficiently paired together and ran as dual core.

The Core Duo is Intel's first generation dual core processor based on the Pentium M (a Pentium III-4 hybrid) made mostly for laptops, and is much more efficient than Pentium D.

The Core 2 Duo is Intel's second generation processor made for desktops and laptops designed from the ground up to be fast while not consuming nearly as much power as previous CPUs.

Note - Intel has dropped the Pentium name in favour of the Core architecture.

Here are some information about both processors side by side.
  1. Architecture
    Core 2 Duo : Uses an architecture ton create two cores on a single die or in other words there is two chips in one package.
    Dual Core : It is the first Double Core Technology from Intel. It uses a less sophisticated mechanism but basically it uses two cores in a single die.
    Conclusion : Dual Core is an older architecture and Core 2 Duo is an improvement over that architecture making it more efficient.
  2. Performance
    Core 2 Duo : It has better performance than Dual Core Processors in almost all Benchmarking tests.
    Dual Core : It is better performer than all previous processors in Pentium Series but no better than Core 2 Duo.
    Conclusion : Core 2 Duo is a clear winner here.
  3. Thermal Output
    Core 2 Duo : Core 2 Duo Processors are significantly cooler than all other processors.
    Dual Core : Remains cool but not like Core 2 Duo.
    Conclusion : Core 2 Duo wins here.
  4. Overclocking
    Core 2 Duo : They can be easily overclocked up to 4.0 GHz with suitable coolers. Even a overclocking at 6.0GHz was made possible with Liquid Nitrogen cooling.
    Dual Core : Can be overclocked upto 20-30% of its specified clock speed without much problem.
    Conclusion : Core 2 Duo has better overclockability.
  5. Power Consumption
    Core 2 Duo : Very good power efficient processor with max TDP of 65Watts.
    Dual Core : Extremely power efficient with max TDP of 15Watts.
    Conclusion : Dual Core has lower power consumption.
  6. Clock Speeds
    Core 2 Duo : Greater clock speeds of upto 3.33 GHz is available now. (Model No. E8600)
    Dual Core : Not so high clock speeds available. Max 2.33 GHz is available for model no. T2700.
    Conclusion : Core 2 Duo models are available with greater clock speeds.
  7. Price
    Core 2 Duo : These processors are priced from $120 to $270 for different versions of processors.
    Dual Core : These processors are priced from $40 to $140 for different versions of processors.
    Conclusion : Dual Core Processors are available at really low prices now.
  8. Cache
    Core 2 Duo : You can get a max of 6MB L2 cache for Core 2 Duo per core. (E.G. Model No. E8300, E8400, E8500, E8600, …)
    Dual Core : Max 2MB L2 cache is available per core.
    Conclusion : Core 2 Duo models are available with greater clock speeds.
  9. Front Side Bus Speed
    Core 2 Duo : It is available with front side bus speeds of upto 1333 MHz. (E.G. Model No. E8300, E8400, E8500, E8600, …)
    Dual Core : Max of 667 MHz speed is available.
    Conclusion : Greater FSB Speed is available with Core 2 Duo.
  10. Overall
    Core 2 Duo : It is a better processor with higher price tag.
    Dual Core : It is not as good as Core 2 Duo but is available at a cheaper price tag.
    Conclusion : If you are looking for a budget processor, go for Dual Core otherwise Core 2 Duo is a better choice.
