What is the difference between a processor like a Pentium D that is listed as being Dual Core, and a processor like an Intel Core Duo or Core Duo 2?

dual core is old technology and core duo is the second generation of dual core proccessors, faster

I believe the Pentium D is essentially 2 Pentium 4 cores on a single die. Could be wrong on that tho.
The Core is so much more efficient than the Pentium 4 - which was just something that should never have happened - so even at lower speeds it can perform operations faster.

Re: Help an idiot out

Thanks. How do the Athlon chips compare? What version of an AMD processor would be the equivalent of a Core Duo?

Re: Help an idiot out

tough question, amd used to be miles infront but the dawn of intel core duo changed all that, i,m not 100% on this but dual core amd's are quite quick and cheapers but i do not know how they compare with core duo chips appart from price, u will get a dual core amd for less money but if i,m correct the core duo will out class it for performance but then again the new am2 socket of amd i dont know a lot about just now, its a cut throat buisness and always will be but from what i,ve been gathering intel have been making some really sick chips @ the moment but like i said it swings around from time to time

performance = bigger hole in the pocket

Re: Help an idiot out

The Core 2 Duo processors have a 2 Meg L2 Cache and everything older is a 1 Meg (or smaller) L2 Cache. This essentially tranlates to a notably faster performance.

Not sure how the AMDs (at least for the hardware in home use) compare to Pentiums. Afaik, Intels rule on the PC / Laptop front and AMDs are kings on servers (Opterons will smoke the Xeons 6 ways from Sunday and then some)

used to be the opposite way around due to the fact that intel had there chips running on lower voltages

i guess it changes all the time

Re: Help an idiot out

Close call I think, Pentium has the L2 but lower communication bandwidth with the rest of the system (FSB speed), even though they've upped it AMD is still about twice as fast. I guess it translates to Intel being able to receive more orders and AMD getting less but being able to execute more at the same time?

I'd love a chip with the best of both...
