All dual cores available are 64 bits man. So dual core is 2x64bit CPus.
So Dual core will be anyday better than a single 64 bit core.

ya, older opterons, Xeons and some IBM proccys

Hmmmm....
All opteron were based on K8 architecture which is AMD64, so not a single Opteron is 32 Bit ;)

Dual Core Xeon came in two cores, 'Dempsey' and 'Woodcrest' both made with 65nm and are 64bit ;)

As for IBM, their first Dual Core CPU was the 'Power4' and it also was 64bit.

So i think it is safe to assume, there never was a 32bit Dual Core CPU,am i right ?

Even if there is 32 bit dual core they would still win against 64 bit single core.
Compare the performance between a 64 bit single core PC running Windows 64 bit and a dual core running Windows 32 bit. Who wins? dual core. why?
Because performance increase of Win 64 bit over Win 32 bit is marginal. But performance increase a dula core vs single core is 30% to 60% depending upon the type of application you are running.

Dude update your knowledge, Intel Core Duo (Not Core 2 Duo) is a 32 bit dual core processor. It does not carry the Intel's EM64T instruction set, which makes Intel processor's 64 bit.

Nope not all dual cores are 64 bits (both Pentium D and C2D) inclusive ....

Agreed all server CPU listed by @Darklord are Dual Core and 64 bit....

Dual core will consits of twice number of cpu registers(comapred with singleton) whether they work on shared cache(Pentium D) or seperate cache (C2D) anyway they will give a kickass performance compared to singleton 64bit cpu....
Wait...... Just aien't over yet...
these bits coressponds to they storage of cpu registers ( AX,BX,CX,DX,SS,ES) since previously they were 32 bit hence also the instruction given to them to perform most of the applications are 32 bit binaries or can be ported to them as of present the 64 bit is not in much use yet.. presently they will perform better to 64 bit but may be when most of the binaries are 64 bit and if we cruch the numbers real closely ... hmmmm.. subtracting the overheads performed by 32 bit core to implement a 64 bit instruction........ i can say it just might a 64 bit race ahead of dual core.... then i guess i cannot be sure just of yet.........]

I am having a hard time finding NON 64bit Dual Cores, care to show me some ?

Dual core will consits of twice number of cpu registers(comapred with singleton) whether they work on shared cache(Pentium D) or seperate cache (C2D) anyway they will give a kickass performance compared to singleton 64bit cpu....-----> I thought Dual Core meant,the CPU had 2 x physical cores meaning its like having 2 physical processors.isnt it ? correct me if i am wrong :S

shared cache(Pentium D) or seperate cache (C2D)------> Nope,its the other way round.C2D have single large cache which can be shared by both cores. ;)

kickass performance compared to singleton 64bit cpu-----> I think it doesnt take a rocket scientist to say that Dual Core which is like having 2 Physical CPUs will be faster than a Single Physical CPU ;)

Hello!!! Pentium D is a 64 bit dual core processor. I have it and I've installed FC5 64 bit on it.

Just did a search on google. I agree with this. They are 32bit dual core.

DUH!!!! the cpu core consits of these cpu registers only that makes up the (ALU+MU+CU) you got your procy CORE.... Though i am preoccupied nowadays..... i am sure there are 32 bit dual core cpu right now... do as blackpearl said...... there are results.... supporting that i did not dig enough so plz forgive if its wrong........ It has been a long time since i have done some digging with whats is what...... but shared cache in C2D doen't make sense...... if they are independant cores any way editing the above post to avoid any confusions..........

i put up this ques coz my friend has Core 2 Duo and i have AMD athelon 3500+

lookes like he is winning

offcourse he will win coz C2d beats athlon 64 by a huge difference, but X2 can perform somewhat close to C2d series....

There is no dual core 32 Bit for desktops.....Core Duo is/was for the notebook platform.....and that is where Intel came with actual 64 Bit dual cores for the desktop market......

well what SAM says is absolutely right :D , but AMD came up with the first ever 64bit processor in the world.... :p

Lol i was expecting this to come up.Intel Core Duo as you mentioned is 32bit,agreed but it is not a desktop chip ;)

Actually it was Intel again, Intel Xeon series of processors was(is) the first true 64 bit processor.
AMD's 64 bit processor is a 32 bit instruction set, STUCK on an existing 32 bit processor, thus making it 64 bit. Its not a native 64bit processor.
Yes, AMD did come up with the first dual core 64 bit processor AFAIK

And I do not think we are differing on the facts dealing with the CPU platform, Laptop, Desktop or Server.
