Question on multicore CPUs

post #1 of 8
Thread Starter 
I wasn't sure where to ask this, so I decided to post here. Which is faster assuming all variable factors are the same....

One CPU with 3 cores or multiple CPUS each with a single core.

Or are they roughly equal in speed?

Just trying to picture in my mind when some one says a processor has 2 cores is it like having 2 CPUS in the machine.

A dual core CPU would be just like having two of the same speed single core CPU's in a system. There might be some small differences but overall you probably wouldn't beable to tell by system performance.

Actually it's real simple. Two processors have to communicate through the motherboard...a dual core communicates right to each other...less latency = more speed.

Right now there is very little software for dual cores, maybe in the future.

Yeah, but what made me think of this was the specs for the XBox 360. It has a tripple core IBM Power PC processor with each core running at 3.2 gHz. isn't that more poerful than most pcs on this board?

It's slowly growing in support, even NVidia has added some support in there video drivers.
Dual core CPUs can be utilized to ...
example, Fold two seperate jobs, or 1 Folder and allow you the resourses of the second core to do other things freely.

yeah there pretty cool- i mean now i can run prime torture test on one core and open up multiple other apps with the other core (say play a game, do stuff online ...) and it doesnt even phase my system now where as with one core it would well you would have to be patient

Except it dont work that way

Fold and open task manager you will see both cores at approx 50% usage each,,Thats because SMP (Symetrical Multi Processing) shares the load as evely as possible Between both cores . .
