What is the difference between dual core and core 2 duo?

is there any difference besides price, and if so how much better would a core 2 duo perform?

I dont quite understand the question... a core 2 duo is a intel brand of dual core procs. It's different than the pentium Ds. Core 2's scream compared to a Pentium D.

It depends what core 2 you are talking about... Intel's flagship will smoke an old pentium D or AMD X2 by twice maybe three times in some benchmarks.

Oh I see...

As you can see they both have the same core... but the e4500 has more cache and runs .2 higher...

You will get more performance just because of the cache... the operating frequency doesnt play a huge role because you can easily overclock to make one faster... check out the charts too.

Taken from THG:

"The Pentium Dual Core, which we found to be an excellence choice for overclockers on a low budget, is based on the popular Core 2 architecture. In fact, the processor cores are the same, but the CPU comes with only 1 MB L2 cache instead of 2 MB or even 4 MB. In addition, some features, such as Intel's Virtualization Technology (VT) are disabled. The result is a castrated Core 2 Duo processor, using the small cache size and limited to 1.6 to 2.0 GHz clock speed at FSB800 system speed."

Please see: http://www.tomshardware.com/2007/0 [...] dual_core/ for more information and a good overclocking article.

If you are OCing it's not worth it. If you are not OCing it's worth it.

the core 2 duo cpu is far better in performance and a better overclocker, just spend the extra money on the core 2 duo. you won't be disappointed Just type in core 2 duo benchmarks on google.

Intel has, or had, several lines of dual core processors, including:

1. Pentium D - the early model for desktop - now the slower model with higher power requirement and more heat

2. Core Duo - the first dual core laptop chip - now the slower model

3. Core 2 Duo - the current, more powerful dual core chip, the mainstream and enthusiast chip for desktop and laptop

4. Pentium Allendale Dual Core - a current, less expensive desktop chip with smaller cache, but still very adequate for general mainstream computer use

Did NO ONE read my post?

And two years later you will be able to build an even faster computer for under $2,000.

I have been struggling with this question for quite sometime and kept on getting more confused after going through all the super technical explanations. However found that this article about difference between dual core and core 2 duo provides one of the best not so technical explanation of this difference.

Last time you linked this article it was apparently too verbose: http://www.tomshardware.com/forum/ [...] e#t1940556
