Difference between Quad Core and Dual Dual Core?

John mentioned here that the portableapps.com server runs off a "Dual dual-core AMD processors". My question is what is the difference, if any, between a Quad-Core and a Dual Dual-Core?

hmmm

Well there really shouldn't be much of a difference except the Quad core is probably more integrated and maybe slightly faster then a dual-dual core :S Don't quote me though....
Thanks,

This is how it was explained

This is how it was explained to me:

Single core- all work on one processor.

Dual core or more: work balanced between cores communicating with each other.

The maximum power for any single core is around 3 GHz. But, you can have two cores do the same work as one more efficiently because the single core has to juggle tasks. Dual cores and above share the load, no single processor taking more than another.

Dual vs Quad- Four cores get better performance because they have half the load of a dual core.

Hope I didn't lose you.

Hey! Where'd it go?

There is really no0t that

There is really not that much of a processing difference. I have a dual dualcore Xeon server at home and a dual single core PowerMac G4 as well. Multi core (dual/quad/tri/oct)means that there are a set number of processors on a single die (silicon). Multi processor means there is more than 1 die in the computer. as far as i have read the highest avalible for home use is a quad quad-core server. this means it has the equivalent of 16 processors in it. hope this helps.

Edit: a DIE is the ceramic casing so multi core means there are more than 1 silicon processors in a ceramic die.

i think the answer is this...

a "Dual dual-core" is a computer hosting 2 physical processors each with 2 cores on the die. meaning 2 sockets, 2 physical processors, 2 cores per processor, 4 cores alltogether.

You are dead on. The server

You are dead on.

The server has 4 cores total. Two physical CPUs, each with two cores. Typically the more condensed the processors are, ie - a single quad core processor, the faster they will run because of the greater bandwidth and less traversing the data will have to do.

I too feel like a quad core

I too feel like a quad core should outperform 2 x dual cores since everything is probably better integrated to work with each other...

I rather would have 2 quad-core processors in my computer Wink but alas money is what I don't have.

I rather have that Quad

I rather have that Quad Quadcore with 128GB ram and up to 16TB HD space :3 But then agian the new Octcores are comming soon.

u know u can't use anywhere

u know u can't use anywhere near that much RAM if u keep a 32-bit operating system. Anything beyond 4GB is useless because the 32-bit architecture can only create 4GB of address space
