Whereas   Intel Core or Intel Core2Duo is a registered trademark [™] of the Intel   Corporation. Many peoples (even geeks) sometimes gets confusion between  core 2 Duo & Dual Core or Dual Core & Core Duo. The fact is all   the above mentioned processors are Dual Core processors.   What is Dual  Core  Architecture :   Once upon a time when  human realized that in a normal atmosphere its  not possible to increase  the CPU Clock speed above standard levels  because of too much heat  generated by CPU, Both Intel & AMD have  hit the Clock speed boundary  line. Heat is enemy of any processor and  high <a href="http://lh3.ggpht.com/_LcG3XjAC3Eg/SmZZPcPTMQI/AAAAAAAAANI/JMQbDvtka7I/s1600-h/image%5B44%5D.png" target="_blank"><img src="http://lh6.ggpht.com/_LcG3XjAC3Eg/SmZZQC__IGI/AAAAAAAAANM/pYKU9wjhjl0/image_thumb%5B26%5D.png?imgmax=800" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>clock speed means  high heat and that means  errors or “BOOM”. Desperate need of more speed (  faster processing) is  the basic reason of why technology turned or  shifted to Dual Core. So  rather then increasing the clock speed of  Processor it was decided to  put two CPUs in One. That is what we call  Two Cores or Dual Core.  Nowadays Quad Cores (4 cores) and even Dual Quad  Cores (8 Cores) are  there in market.   In a layman’s tongue  here's an example. Let's say a single core  (Pentium 4) is a two lane  road with traffic running at 100kmph, and a  Dual Core is a four lane  road with a traffic running at 100kmph, and a  Quad core is eight lanes  running at 100kmph. All lanes (cores) are  running at the same speed, but  more lanes (cores) can pass a lot more  traffic (Information or Data)  than a single.  Dual core technology refers to two individual  microprocessors on a  single die cast chip. This is essentially two  processing units (CPUs)  in one. The advantage of a dual core chip is  that tasks can be carried  out in parallel streams, decreasing processing  time.  Now lets see the difference & Compare all of them  line by line as  per their release sequence. Intel <a href="http://lh5.ggpht.com/_LcG3XjAC3Eg/SmZZR3uTutI/AAAAAAAAANQ/Emzli2tqQJM/s1600-h/image%5B13%5D.png" target="_blank"><img src="http://lh4.ggpht.com/_LcG3XjAC3Eg/SmZZS-xafDI/AAAAAAAAANU/zfr1wGwpnJs/image_thumb%5B9%5D.png?imgmax=800" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>has, several dual  core processors mentioned  below.  1. Intel Pentium D  - The early model for  desktops. CPU comprised two dies, each  containing a single core   residing next to each other on a multi chip  module.   Pentium D  is slower than any one of the below, It consumes higher  power  and so it  gives more heat and even its not good in terms of Over  Clocking.  2. Intel Core Duo  - The Core  brand refers to Intel’s 32-bit mobile dual-core x86 CPUs  that derived <a href="http://lh6.ggpht.com/_LcG3XjAC3Eg/SmZZTvTdUTI/AAAAAAAAANY/JUdth2Pzyl0/s1600-h/image%5B18%5D.png" target="_blank"><img src="http://lh5.ggpht.com/_LcG3XjAC3Eg/SmZZUhSoObI/AAAAAAAAANc/1j70dp-4FDI/image_thumb%5B12%5D.png?imgmax=800" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>from  the Pentium M  branded processors. The Core  brand comprised two branches: Duo  (dual-core) and Solo (Duo with one  disabled core, which replaced the  Pentium M brand of single-core mobile  processor). Core Duo was Intel's  first dual-core CPU for laptops. It's  a whole new architecture, using  two cores on a single die, which  simply, gives you two chips in one  package. Running at lower speeds  than the old Pentium line.  The  Core Duo conserves substantial power & racketing up clock  speed  while offering what was, at the time, record-breaking  performance.  3. Intel Core 2 Duo  - The Core  2 brand refers to a range of Intel's consumer 64-bit  x86-64 Single,  Dual  and Quad Core CPUs based on the Intel Core micro  architecture.  The <a href="http://lh4.ggpht.com/_LcG3XjAC3Eg/SmZZVi9TsrI/AAAAAAAAANg/2dfqzJHuAE8/s1600-h/image%5B22%5D.png" target="_blank"><img src="http://lh6.ggpht.com/_LcG3XjAC3Eg/SmZZWUgWYUI/AAAAAAAAANk/XJXhUyv9toI/image_thumb%5B14%5D.png?imgmax=800" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>single and Dual  Core models are single die,  whereas the Quad Core models comprise of two  dies, each containing two  cores, packaged in a multi-chip module.  Core  2 Duo processors are much popular these days, It has more  powerful Dual  Core chip, The best performer, It consumes less power in  comparison to  any of the above mentioned CPU. No over heating issues,  it runs cool and  a perfect Over Clocker. Once “I” overclocked my Core 2  Duo E6750  (2.66Ghz)  to 4 Ghz on air with Sunbeam Core Contact  Freezer. System was  completely stable and temps were awesome.  4. Intel Pentium Dual Core  -The  Pentium Dual Core, which we found to be an excellence choice for   overclockers on a low budget, is based on the popular Core 2   architecture. In fact, the processor cores are  the same, but the CPU   comes with only 1 MB L2 cache instead of 2 MB or even 4 MB. In addition,   some features, such as Intel's Virtualization <a href="http://lh4.ggpht.com/_LcG3XjAC3Eg/SmZZXcm4ZeI/AAAAAAAAANo/L4jj2_zVff0/s1600-h/image%5B26%5D.png" target="_blank"><img src="http://lh6.ggpht.com/_LcG3XjAC3Eg/SmZZYaWKNLI/AAAAAAAAANs/gym_O-bqvck/image_thumb%5B16%5D.png?imgmax=800" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Technology (VT)  are disabled. The result is a  castrated Core 2 Duo processor, using the  small cache size and limited  to 1.6 to 2.0 GHz clock speed at FSB 800  system speed.  Intel Pentium Dual Core are  based on either the  32-bit Yonah (T2060, T2080, and T2130 for  notebooks with 1mb L2  cache) or 64-bit Allendale (E2140, E2160  and E2180 for desktops  with 1mb L2 cache)   Later on Aug 2008, the 45nm E5200 Wolfdale   Launched for mobile or desktop computers with larger 2mb L2 cache and   2.5 Ghz clock speed. This model is highly suggested in terms of over   clocking. The best over clocker in such cheap price, with some   enthusiasts reaching over 6GHz clock speed using Liquid Nitrogen   cooling.  Intel Dual Core processors are downgraded  version of Core 2 Duo, less  expensive with smaller cache, but still very  adequate for general  mainstream computer use. In terms of performance  its more or less equal  to Core 2 Duos. Intel launched it with very low  cost to grab the lower  end market. Intel Pentium Dual Core Processors  are less power consumer  (65W) in comparison of Pentium D (130W). Though  it has a smaller L2  cache, it has proven to be much faster than the  Pentium D under the  test of CPU hungry applications.<img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /></blockquote>
