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

This isnt the required information. There is too much difference betwwen the two on technical grounds. I am sorry because I dont know about the details but I am sure that there is a difference regarding the cache memmory. Hope so, somebody would come up with a correct answer.

Hi,
This is such an usefull information. But I didn’t get u the 4th point which u mentioned in summary. Please clarify and give me related site.

What I’ve understood from what he said, he means that a Core 2 Duo can be a Dual Core as the Core 2 Duo has 2 (physical) processors and virtual processors also inside the same chip, whereas a Dual Core has only 2 physical processors. Thus, a Dual Core cannot be a Core 2 Duo!
Correct me if I’m wrong!

Excellent information. Now I got a good differentiation between dual core and core 2 duo
Thanks a lot

I think what we as purchasers need to know is the core duo is a 32 bit processor and the core 2 duo is a 64 bit processor other than that I think a 1.83 chip is pretty much a 1.83 chip as far as speed of processing goes if they both are confined to a 32 bit operating system. If the core 2 duo has the 64 bit operating system and a program that is capable of operating at 64 bit then the core 2 duo is going to have a significant speed advantage.

Please friends help me
which one is best
core2due E6400 or dual core E6300
Reply
The core 2 duo E6400 is a bit higher in specs than E6300 in terms of frequency rate.
