Many people are confused what exactly the difference between Intel Core 2 Duo and Between Intel Pentium D or Intel Dual Core processors….
I would try to explain from a END user point a view rather not going in to details architecture over view…
The Simple facts are,
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…
Pentium D is nothing but 2 Prescott Processors side by side… runs very hot, not a good OverClocker…
Intel Core 2 Duo processors are next gen processors from Intel on 65 nm platform… developed from Ground up with new Architecture called Core… so they are whole new Processors just Jump like Pentium 2 to Pentium 3 or Pentium 4… Expect one Core 2 Duo Lowest End Processors like E4400/E4300 taking up and beating Intel Pentium D 3.8 GHz ones with ease 
… runs damn cool and super over clocker…
Intel Dual Core 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 E2140…. these are not Pentium D rather they are same batch like Core 2 Duo based on the new Core Technology…. 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….

you all stupid and i am much greater coz i replaying…
2*2=4
4*4=16
dual core =2 time fast
core 2dou=4 time fast.
The core is the center of the Earth or a planet. It is believed to consist of an iron-nickel alloy, and may have a temperature of 5505 °C.
If it’s a Core 2 Duo then the planet has 2 cores and that means it will have twice gravity and more active volcanoes on the surface.
IF the Dual core is Intel Pentium Dual Core then its twice much more better than pentium 4,even a 1.8ghz dual core kills pentium 4 3.8ghz.
which is more better pentium 4 3.6ghz or intel dual core3.0ghz ? please tell me i am really confused.!!!
Dual Core 3.0 GHz is better
core 2 due is better than
dual core
i know becouse i have dual core
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.
The processor wars have hit a major speed bump as clock speeds become harder and harder to push upwards. Because the number of transistors in a single chip continues to follow its upward trend, processor manufacturers like Intel and AMD have decided to go a different route in increasing the performance of their products, adding more cores into a single chip that leads to a performance boost if the OS supports it. 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.
Basically, the difference between dual core processors and the Core 2 Duo processors is just in the semantics as Core 2 Duo is simply a name given to a more recent family of dual core processors. If we translate this to the single core processors, we can say that Core Duo is Pentium 1 while Core 2 Duo is Pentium 2, while AMD has their own processors with different names; but all these are still single core processors. We can therefore say that Core 2 Duo is simply a subset of all the dual core processors that are out in the market today.
Summary:
1. Dual core is the generic name given to processors that have 2 cores on the same chip
2. Core 2 Duo is the second line of dual core processors from Intel
3. Other dual core processors aside from Core 2 Duo are the Core Duo from Intel and the X2 series from AMD
4. All Core 2 Duo processors are dual core but not all dual core processors are Core 2 Duo
well no problem whatsover,Intel Core 2 Duo has 2 cores,so does dual core also has 2 cores.just a small difference of cache and bus speed.not any thing more.you get a brand name.Core is nothing but the entire stuff…In human being your brain is called as core….similarly in computer technology core refers a single processor..dual core refers 2 processors…
so there is no big difference between core 2 duo or dual core.both have 2 cores,both are good at overclocking.Intel has stopped making core 2 duo new models,however pentium dual cores are now being made by them in lga 1156.
i use toshiba laptop satellite L305 and cant install windows xp ive tried all i can but all yielded negative results
what do i do?
is core 2 duo 1.8GHZ faster than a dual core of 2.2GHZ and why?
also my laptop has the following specs
intelcore2 dou 1.8 GHZ
888mb graphics
128mb dedicated for gaming
2GB memory
but still cant play most games
please how do i upgrade my graphics memory for games sake?
And you must know that lap-tops aren’t best for gaming..:\
I suggest you to buy:”Graphic Card 80-90$,Motherboard 80-90$,(if you want)Hard Drive 1000 GB 100-120$,RAM Memory Kingston 2-3 GB 30-40$,Processor Phenom II X2 555 Black Edition 90-110$”,and create your own PERFECT PC…As I know this is great configuraton,but you don’thave to buy that Hard Drive.You Can buy samo of 500 GB,i suggest it becouse you want good gaming PC
what is CORE? how it is different from others?
core 2 duo is beta than the pentium dualcores becoz its available in high FSB speeds L3 cache and the grea hyper threading techo
oh common core 2 duo has 2 cores,core 2 quad has 4 cores,pentium d is old but contains 2 pentium 4 cores thats why its meant to be dual cpu.core 2 duo and pentium dual cores are same just a little difference.check everything here:
http://en.wikipedia.org/wiki/Intel_Core_2
I am bad at English and I have 15 years,but I work with computers 8 years.What’s the fuck up….Dual Core have 2 cores,Core 2 Duo have 4 cores.Like Awais said Duo means 2 so Core 2 Duo is 2 Core x 2 times = 4 Cores…If you can lift weights with 2 hands it will be easier if you lift weights with 4 hands…It will be easier and it will go faster.It;s same like processors…If 2 Cores are overloaded,work will be devided into 4 Cores,so processor will be work faster and your computer will work faster…:@@@
Example:
Intel Pentium D 3.4 GHz – It’s one core,so it’s 3.4 GHz
Intel Dual Core 3.4 GHz – It’s two cores,so it’s 3.4 GHz x 2 = 6.8 GHz
Intel Core 2 Duo 3.4 GHz – It’s four cores,so it’s 3.4 GHz x 4 = 13.6 GHz ……….THIS IS JUST EXAMPLE
I THINK YOU GET IT NOW…p.s. sorry for my bad english
I like quad core . core 2 is running too slow than quad core .
Core 2 Duo!duo means 2 so core 2 duo is same to pentium dual core.if looking for gaming dual core is best option according to price/performance/overclocking ratio.
still do not know what is a “core” ? ? ?
It’s 2 Cores u idiot.
Core is nothing but the entire stuff…In human being your brain is called as core….similarly in computer technology core refers a single processor..dual core refers 2 processors…
Core 2 Duo – 4 Cores
Dual Core – 2 Cores
What’s the problem?
That a Core 2 Duo has 2 Cores
A Core 2 Quad has 4 Cores
I cannot believe how dumb you all are.
Time to start talking about Core 2 Duo P series, Core i3, i5, i7, Athlon, Athlon II, Phenom and Phenom II cores.
core 2 duo has 4 cores while dual core has 2 core so core 2 duo is faster than dual core as all processes divided into 4 cores to work faster.
Core 2 Duo has 2 cores u dumb ass! learn ro read before u post misleading comments
i am a electronic engineer and i have purchase computer parts seperatly and have core i7 with 8gb ram, build in 2300mb graphic card in my board,my full system around 240 us dollers and 18 inch dell LCD MONITOR for 60 us dollers.
even i purchase my LCD in parts and saved money.
can i believe on all. ha ha ha
