Dual Core means what looks like a single CPU on the outside actually contains two seperate processors on the inside. Quad Cores contain 4 cores. These all fit into a single socket.
There are a large number of "Dual Core" processors on the market.
The "Core 2 Duo" is one of these and is the fastest.
Both Intel and AMD have been making Dual Core processors for a few years now.

Hey guys, I'm not sure about this, but I think the OP is referring to the E2XXX series, the ones based off the Allendale core. They are listed in a separate section of "dual-core" under Newegg's search feature, so that might be what he is thinking of.
@OP: if that be the case, then the only difference is that the L2 cache on the E2XXX is 1MB, whereas the E4XXX series have 2MB.

There are new "Dual Core" CPUs from Intel. They consist of the E2xx and T2xx family. The official family name is "Intel® Pentium® dual-core processor".

What is the difference(s) between CORE 2 DUO vs. DUAL CORE?Whelp:
Intel Core 2
Pentium D
The both contain 2 cores (processors) in a single package like Zenmaster pointed out, and the Pentium D is a predecessor, which is something to stay away from... Unless you need to warm up a room during those cold winter nites.

Grimmy with all due respect that's why I said E6300 and E6400 because all the other E6*** models have 4MB but those two are 2MB. Not that there is any reason to buy either of them anymore since the E6750 is about $11 more than the E6300.

So don't freak out, I wasn't trying to correct ya.
Actually the 6750 is 10 bucks cheaper then the 6420 on newegg.

Thanks for all the help and info. I guess I should have been more specific. I was inquiring about the structural differences, and if there was a structural difference, was one considered a true dual processor and the other not?
It appears that there is really not a difference other than calling the newer version (of the same product) something different.

From a CPU standpoint, there's no difference in processing power between a dual core and a core 2 duo at the same clock speed. Only difference is dual core has less L2 cache. Here's sandra copy/paste from my two laptops, one w/ a c2d and another w/ a dual core.

Basicly intel have messed up. For example, the E5200 is Dual Core, BUT with the new 45 nm technology, like core 2 quad. Most, or many core 2 duo use 65 nm, and generate more heat and use more power.
It also has 2 MB of L2 cache and runs at 2.5Ghz. And half the price of a core 2 duo at 2.5Ghz.
SO, I don't think a core 2 duo, with twice the price is twice the better.
Besides, this clocks easy up to 3.5 - 4 Ghz ;D

A lot of this confusion has been created due to intel using similar names for 2 processors that are quite different. I have been breaking my head for quite sometime over this issue. Got some clarity after reading the . http://binaryday.com/2009/01/15/difference-between-intel-core-2-duo-vs-intel-dual-core-vs-intel-pentium-d/ . Quite useful for technically challenged people like me

C2D > PDC3.8Ghz PDC > 2.6Ghz C2D
Too many factor's to take into account but if you have a 2.0-3.0Ghz PDC and are looking to upgrade. The C2D is the way to go. If you have a 3.6-3.8Ghz PDC i'd look for a way to get to 4Ghz and maybe call it a day.
Er... PDC is pretty much the same as a C2D. Take away some cache, VT and usually a little clock speed and you're left with a PDC. If you're looking to upgrade you'd be better to move to a C2Q for some tangible performance improvements.
Now if you're talking about a PD it's a different story.
Somebody post a necro card.
