dual core is 2 cpu in a package

2 cpu's in a die = 2 cpu's made together
2 cpu's in package = 2 cpu's on small board or linked in some way

core 2 duo = brand name of certain kind of cpu like pentium or amd atholon

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.

Yes but is there any difference in performance? say that the e2180 and e4500 were both 2.0 ghz ( I know there not) would the e4500 be that much better, beside ocing power?

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.

DO you see it being worth it to buy the e4500 for the extra 40 on a tight budget? i am only going to use it for things like mp3 ripping and some slight gaming, mostly c&c2 RA

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."

i'd say its worth 40 if theres nothing else.

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

The only difference is the core2dua doesn't have any cheese between the meat patties but the D does.

Ask thunderman about the cheese ... LOL !!!!

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.

either way you won't see much difference unless gaming... and even then there won't be a huge difference. just overclock it and it'll run anything fast. I'd say run them up to 2.8ghz or higher and you'll be extremely happy

http://www23.tomshardware.com/cpu_2007.html?modelx=33&m...

here's the e4300 and the 2160 which are both at 1.8ghz. This is almost exactly what you'll see with by comparing the 2.0ghz models against each other. if you're not gaming you won't notice any difference and i'd highly recommend getting the cheaper 1, but if you are a gamer, you'll notice a little difference.

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

As you can see you CAN OC the E21xx chips quite a bit.



Did NO ONE read my post?

As you can see from supremelaw and rallyimpresives explanations... there is really no choice but to save up your piggy bank until you can get a "conroe".

Or you can spend the little money that you do have and in a few months time you'll start regretting it... What I would do is save your money up until you have so much that you can build a "dream machine" or a computer that can play crysis at max settings while listening to your favorite music and burning a DVD and not to mention downloading a movie online.

That should run you 50K!

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

Get the cheaper one. Do not save up your money for a "conroe". The e4 series are allendales The cheaper e2 series are also allendales which are nothing but conroe c2d's with less cache and a 800fsb. Which makes overclocking them very easy.

the 4 series has 2mb of cache the 2 series has 1mb of cache.

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.
