Pentium Duo and pentium Dual Core 3 gig which is fastest and why?

Question

I read that a pentium duo at 1.8 gig or 2.3 gig is faster than a dual core pentium d 3 gig as it has two processors, this means that the 1.8 or 2.3 is double giving 3.6 speeed and 4.6 speeed respectably.

This is not logical to me unless each task that is running is equally split between the two processors on the 1.8 and 2.3 gig duo. The 3gig dual core is always running every process at 3 gig so prove to me that the lower speeds are better.

Thanks in anticipation

Answer 1

that question makes no sence but i will try to figure it out. a pentium D is 2 Pentium 4's on a single socket. the core 2 duo is 2 64 bit pentium M processors on a single socket, core 2 duo processors run cooler that pentium d's. core 2 duo is faster than pentium d. its not always the case that it is doubling the clock speed with 2 cores. the cores work together and some programs can use both cores separately to do different things, which is wat ppl though 2 processors would do bac in the day.

Answer 2

just forget all this, they are essentially the same, a core 2 duo extreme is the best dual core chip out, doesnt run at double the speed cuz there are two processors or anything like that. thats like saying does a quadcore 3ghz run at 12ghz, not a chance in hell, it runs at 3ghz over 4 cores... just buy a quad core call it a night.

Answer 3

its extremely complicated to explain... it really has to do with how much work is getting done while the processor is running at 1.8/2.3ghz... the Core2Duo does more work per clock cycle than a dual core pentirum 4 does (even if it is running faster)... hard to comprehend... but its true...
