Difference B/w Intel core 2 duo, Intel Pentium D & Intel dual core
 
Many people are confused what exactly the difference between Intel Core 2 Duo and Between Intel Pentium D or Intel Dual Core processors.
Here are the specification  :-
All Core 2 Duo Processors are Dual Core Processors
All Pentium D Processors are Dual Core Processors
All Intel Dual Core Processors are Dual Core Processors
The Intel┬áCore 2 Duo is Intel’s second generation (Hence, Core 2) processors from Intel on 65 nm platform made for desktops and laptops designed from the ground up to be fast while not consuming nearly as much power as previous CPUs. so they are whole new Processors just Jump like Pentium 2 to Pentium 3 or Pentium 4ΓǪ Expect one Core 2 Duo Lowest End Processors like E4400/E4300 taking up and beating Intel Pentium D 3.8 GHz ones with ease┬áruns damn cool and super over clockerΓǪ
The Pentium D  brand refers to two series of dual-core 64-bit x86 processors with the NetBurst microarchitecture manufactured by Intel. Pentium D is nothing but 2 Prescott Processors side by side… runs very hot, not a good OverClocker…
Intel┬áDual┬áCore┬á Processors are just launched striped down version of Core 2 Duos.. there are 2 in Market for Desktop range, E2140 runs at 1.6 GHz with 1 MB L2 and 800 MHz FSB and E2160 with 1.8 GHz with same specs of E2140ΓǪ. these are not Pentium D rather they are same batch like Core 2 Duo based on the new Core TechnologyΓǪ. they perform same like Core 2 Duos but they were launched with a very low price to counter the market of super low cost but high performer AMD X2 range line up to AMD X2 4000. The Dual Core processors use single cache shared between the 2 cores… plus, the size of this cache memory is usually less as compared to Core2 Duo ones (typically in size of 128 KB to around 512 Kb or 1 MB)
