CPU/Mobo Difference between Dual Core/Core 2 Duo

Dual Core is a general term (not related to any brand) meaning that there are two cores inside a single physical chip. Similarly Quad Core means that there are 4 cores inside a single physical unit.

Core 2 Refers to a Processor Model from Intel like the Pentium, Pentium 2, Pentium 3, Pentium 4 etc. Core 2 Duo means that its a Dual core variant belonging to the Core 2 line of processors. Similarly Core 2 Quad means that its a Quad Core processor belonging to the same Core 2 family.

Core2 is the latest generation of processors from Intel. The earlier one was called Core and came in Core Solo (Single Core) and Core Duo (Dual Core) variants. Earlier to that there was the Pentium D line which were again Dual Core processors from Intel. Similarly AMD also has a Dual Core line called the Athlon X2.

It seems that though Dual Core is a general term, the computer vendors have began to refer to the Pentium D lineup as "the Dual Core". But as I mentioned its a general term.

Hope this cleared up things for you. :D

but can u giv me specifically the diff in the speeds??

The clock frequency means nothing and how the frequency is used is what matters. The Core 2 Duo use a completely different architecture from the Pentium D line and hence even at the same frequency the Core2 will be faster than the Pentium D. A Core 2 Duo clocked at 1.86 GHz (E6300) can hold its own against a Pentium D clocked at 3.2~3.4 GHz. These processors are also highly overclockable adding to their value. If you want a Dual Core processor and cannot go for the Core 2 line due to the cost, then it would be better to go for the Athlon X2 rather than Pentium D.
 
Answered that in the previous post itself. :) Another thing, What you are referring to must be the Pentium D 820 and not Core Duo. Core Duo is a kind of processor belonging to the first generation of the Core series and widely used in Laptops and in Apple Intel based Mac's

oh k... so my the speed of a Core 2 duo is 1.66 Ghz but its faster dan a 2.66 Ghz Dual core...got it correct na?? thanks!

The lowest in the current Core 2 Duo lineup is the E6300 @ 1.86 Ghz running on a 1066 MHz Bus. There are other Core 2 Duos clocked at various speeds like E6400 @ 2.13 Ghz, E6600 @ 2.4 GHz, E6700 @ 2.66 GHz, X6800 @ 2.93 GHz. There is a new lineup comming with the E4300 clocked at 1.8 GHz running on a 800 MHz Bus.

What I wanted to convey is that even the Core 2 Duo Clocked at 1.86 GHz can easily better the 3.4 GHz Pentium D in terms of performance. If you need a better processor than the E6300, you can pick one of a higher frequency at a higher cost. :D
 
a simple reply wud b tht core2duo is da best cpu existing. though pentiumd is also dual core but it is no match near core2duo(due 2 overheat problem). my advise wud be core2duo > amd x2 > pentiumd. Dont go by clock speed, 1.83GHz core2duo perform much better than 3GHz pentiumD
