3ghz quad core is 12Ghz in theory?

Nah jimbob27's right . . . we are all nOObs, nOObzillas, nOOblings and nOObnOrks . . . I wouldn't want it any other way myself! ;)

I'm not sure he's right about adding up all the MHz/GHz togther though? . . . I think the hardware needs a "Clock Generator" to produce a frequency?

Yeah, my computer has one of them.

Start menu > accessories > Calculator.

I mean how else could I add up the mhz of my ram?:D

(I hope you guys realise I wasn't being serious:p)
 
jimbob27,

there is a knack to conveying "Humour" across the internet . . . I'm not sure if you have quite grasped it yet but keep trying! :p

guys can you clarify one noob issue for me please?

I keep hearing core and thread being used interchangeably. What is the difference between them? My E6600 has 2 cores and two threads. What does that mean in practical terms?

Your E6600 has cores, it doesn't have threads. Threads are a software abstraction that are used to do more than 1 thing at once.

In layman's terms:
Thread 1: Turn on the kettle.
Thread 2: Put on some toast.

Without threading we would have to wait for the kettle to boil to put down the toast!
 
right so, if 4 cores worked at 3GHz on a piece of data to manipulaye it, how fast would a single core have to go to reach that same efficiency?
 
In reality you will never get 12 Ghz because most programs will have threads that will need to sync back to the main thread. Depends how the app is written.

If youre into multithreaded 3d rendering then yes he effectively has 12ghz.

No, it doesn't.

No, it means 4 cores at 3GHz - each job (i.e. each child thread) will be able to run at 3GHz, and you'll be able to do four jobs at once. Rarely in general desktop computing is each "job" identical to one another, so you can't stack things up like that.

You were correct when you said: "well if a programme is fully threaded wouldn't that mean one core at 12GHz = 4 cores at 3GHz? In processing power?"

Some people in this thread are misreading the question and ignoring the bold text or in the case of the OP the 'in theory' part. Nobody is, at least I don't think they are, suggesting that a quadcore 3Ghz gives you a 12Ghz processor, but it does give a processor that has same max theoretical throughput.

The reason that CPU-Z / CPUID reference both cores and threads is so that they cope with Hyperthreading processors like Pentium 4, and I3/5/7.

IE a 4 core I7 will have 4 cores, and support up to 8 concurrent threads.
