dual core vs core2duo

[kickin_da_habit]

Hi guys

In terms of processors, is dual core better or core 2 duo better?

Which should i go for?

 

[BillytheBrave]

I think core 2 duo is better. P3 pc's uses the dual core technology.

 

[Sensorei]

P4s use dual core I thought.

Core2duo

 

[DrJohnZoidberg]

Core 2 duo is the better processor, the core 2 duos have bigger cache's than the dual cores. Sometime you won't notice any performance difference though, depending on what applications you are using it for. You can always just get comparative results at sites like tomshardware. Most of the time you won't need a core 2 duo, the new dual cores are right up there.

 

[Defiler]

All core 2 duo processors are dual core processors, all pentium d processors are dual core processors and all intel dual core processors are dual core processors…

Basically it means is that there are 2 cpu's in one, and intel uses different terminology to class its newer chips from its old ones, and yeah the core 2 duos are the newest/fastest.

 

[BillytheBrave]

like he said...

Also some Dual Core CPU's are 32-bit and not 64-bit to add even more confusion

The difference between C2d and Core duo is the amount of L2 cache available to them. That's it. Architecturally speaking they are identical.

I'm possibly talking utter ***, but IIRC, it depends on the chip. Some Dual Cores have VT (which allows Windows 7 to run in XP compatibility mode), some don't. Different chips have different L2 cache sizes, and it's not consistent.

Look at Intel's website.

Core 2 Duo and
Dual Core

 

[Asha'man X]

Dual Core is a type of technology, as is Quad Core. All it means is that the processor has more than 1 core on it.

Core 2 Duo is Intel's branding for their Dual Core chips. AMD also has dual core chips, generally shown as X2, i.e. Athlon X2

 

[Keeper]

iirc "dual core" only means it has 2 virtual cores - not two "actual" cpu's on one die

core to duo is 2 actual cores, and a quad has 4 actual cores

something like that....not 100% sure

[Jabberwocky]

dual core is the new celeron?

 

[wpswart006]

I think what the OP ment is, Core 2 Duo vs the new Pentium Dual Core's (like the E6300).
In that case C2D will be better , vut The Pentium's will be cheaper.

How can there be so much confusion about such a simple concept?

Dual Core:

• 2 physical cores
• less cache
• slower fsb

C2D:

• 2 physical cores
• more cache
• faster fsb

In general but C2D also has VT while not all dual cores do.

In short: C2D will generally perform better than dual core.

Go read the following:
http://en.wikipedia.org/wiki/Core_2_Duo

http://en.wikipedia.org/wiki/Pentium_Dual-Core

There are also dual core Celeron processors e.g. the Celeron E3300 is basically the same as the Dual Core E5200, just with half the cache.

Celerons are generally based on some processor but with only half the cache of the original and with some fetures disabled e.g. VT, speedstep etc.

Celeron basically began way back with the 8088 and 8086, but I digress.

Not really.....

Introduced in April 1998,[2] the first Celeron branded CPU was based on the Pentium II branded core.

Somehow I think the 8086/88 predates that.

While the 8088 obviously wasn't branded as a Celeron the concept was similar, it has an 8-bit data bus instead of the 8086's 16-bits otherwise they were pretty much the same.

So the 8088 is basically a cr@ppy/cheaper version of another processor - the 8086, just like the Celeron is a cr@ppy/cheaper version of whatever procesor it is based on.

What some people said. The only difference between Dual Core and Core2Duo is the cache. Dual Cores have less cache and will perform slightly worse in programmes that need a lot of cache. The E6300 (Dual Core) is 1066FSB and the E7xxx (Core2Duo) are all 1066FSB so there's not always an FSB difference.
