can someone explain what a quad 4 2.0 GH processor does...I mean am I getting a clock speed of 8 GH or only using 2 GH....am I looking a 4 2GH processors working on one project or is it only good for multitasking....can you give me an anology ...

thanks
 
Just as in a dual core processor it parcels out out the tasks and programs over the multiple cores. Each core in itself is 2Ghz, however, it doesn't "add up" per se. It just allows the allocation of different programs over the multiple cores to more efficiently run the programs as they would on a single core chip.

Overrated IMO.
 
Quad Core is like Dual just with 4 Cores.

Each core could be like 2.3GHZ. Then the the more cores you have the faster the system with be.

some software can make all 4 cores work on one program, otherwise, Windows will try to delegate new tasks to whichever core is working the least.
 
do what?

If you mean making new tasks work on other cores, windows task scheduler does the job for you. You don't need programs to do that for you.
 
i think he meant make a program multithreaded, and no, that is something that needs to be built into the original program

so if windows delegates tasks to all four of the cores what happens when only one of the cores is needed.....do the other three cores work in conjuction with the one core .....
 
If its coded to work on more than one core, it will use however many its coded for. If its not, just one core will be used.
 
People are getting these terms confused. No program out there uses all 4 processes on one task, what you are probably thinking of is a multi-threaded program, which will utilize 2 or 4 cores to work on separate portions of a task, such as in Photoshop or other rendering applications.
 
Now this might be a little off topic... but since it's at least something to do with the topic, I'll ask this anyway:

Can windows move an active thread to work on one of other cores if need be?

It Can.

In the Processes section of the task manager, right click on a process and click set affinity.
 
Thanks for that, but it didn't quite answer my question (i think anyways)

A process can have multiple threads, right? So, when I go to "Set affinity" I can actually set which cores the process is allowed to run tits threads on? I think this is what you meant to tell me...right?

So let's assume there are two threads T1 and T2, both use 20% of available processing power. We have a dual-core processor, and these tasks probably would be running at different cores. So, then comes along thread T3 which needs all 100% of available processing power... so threads T1 and T3 would both be running on the same core, hindering the performance of both threads while the other core would be nearly idle. So can the task shceduler move T1 to the other core, so that T3 can have all the power it needs and less-intenisve threads T1 and T2 run on the other core? Does this make any sense?
