How can we count quad core Processor speed ?

[krzysiek.uk]

Hi, i just had a quick discussion with my mate about counting the processor speeds, i am saying that if the quad processor is 3.2 quad core (quad core extreme) it has the overal speed at 4x 3.2 GHz wchich is 12.8 GHz, he is saying that it is not 12.8 it is still only 3.2.

Whats the truth ? even if it's not any of these please tell us how it's worked out

It'll be classed as 3.2.

Now I await the person with the scientific proof to back me up.:worship:

Depends really...

If you happen to have programs that utilize all 4 cores and all are maxed out processing at 100% load.. Then in theory you could say your cpu is churning away at 12.8GHz.... but even then its not.. Just each of the 4 cores working at 3.2GHz.

Problem is there aren't many programs that are fully optimized for quad cores and even less that will require that much processing power.

Some benchmarks and folding I spose use it all.

It is without any question 3.2 GHz, just a 3.2 GHz with an improved ability to use that 3.2 GHz without having to queue up processes

Ok guys, thanks for quick replys, so it cannot be a 12.8 and it cannot be 3.2 is just 4x 3.2 but we cannot multiply it yea ?

Basically, if you have a program that can take advantage of all 4 cores.. you could probably get away with saying 12.8Ghz.

But at this moment in time not a single aplication uses all cores for one job. Apart from the SMP folding console.

So yeah, you should say "My Quad is clocked to 3.2Ghz" and not 12.8Ghz.

No that multiplication thing is wrong and very misleading towards those who do not understand the way multi core CPUs function. You see it on ebay a lot and it should be cracked down on, hard.

If anything, you have 4 x 1/4 CPUs

Thanks mate, now i know how its worked out, i see on ebay someone says 9.6GHz wchich was wired to me but everyone says that so i fout there is some truth in it but is not. Thing is sorted now.

i agree with llwyd on this one

Folding doesn't use all 4 cores for one process either, if you set all your cores at folding, you would have 4 processes running, each with the affinity of one core each.

BUT, each thread goes towards one thing, the finished unit.. so on paper that would be using 12.8Ghz.

 

[Phoenix]

Yeah, but that's taking it to the next level. It's like when people think they get 10MB/s downspeed on a 10mbit connection.

Its nothing like that

3.2 ghz.

 

[Phoenix]

Period. lol

The speed limit for a motorway is 70mph. If four lanes are in use and every car is travelling at 70mph does that mean the speed limit has been broken by 210mph? (4x70= 280 - 70)

 

[Phoenix]

Obviously, if they're heading for the same destination. lol

Well the most pc savy way u could have explained it was that the cpu has 1.4v (approx) across it, which doesn`t equate to 4x1.4v.

Exactly, the voltage does not increase, the ampage (number of cars) does, increasing the wattage (mass moving along the motorway)

it doesnt matter how you look at it or whether its on paper or not, there is no way you can say youre getting fsb x multi x cores

If you had a board which took 4 3.2GHz CPUs, and a board with a quad core 3.2GHz, which would perform best? (excepting shared cache issues).
