3ghz quad core is 12Ghz in theory?

[Serpantine]

Simple way of putting it is this:

if you have a 3ghz quad core cpu (4 cores, no hyperthreading) which will give 4 threads for tasks to be completed in.

So, any one task can be completed at 3ghz, it cannot use 2 threads to complete the same task this is why coding for it is difficult because you need to split tasks a program does into 'threads'

So, to clarify, no it is not 12ghz, its 4 3ghz processors in effect (minus chipset / application limitations)

When talking to the technically challenged I like to use the example of cars - does owning four, four seater saloon cars each capable of 100mph mean you can drive at 400mph ?

But having four cars will mean transporting twelve people may be a lot easier (drivers permitting, if you excuse the pun) than with a 400mph supercar.

Never have I ever heard(seen) such good comparison. Well done good sirs!

Hi guys I need clarification on the following issue:

Q6600 has 4 cores and 4 threads. So each core can run 1 program effectively at the same time meaning Q6600 is capable of running 4 single threaded cpu intensive programs easily or a program that requires 4 threads.

i5 750 has 4 cores and 8 threads. So this means each core is capable of running 2 programs at the same time meaning i5 is capable of running 8 single threaded programs or a program that requires 8 threads.

Am I right?

i5 750 only has 4 cores and 4 threads its only the i7 as far as i know that has hyperthreading thus 2 threads per core.

Hi all,

A friend of mine has stated that because he has got himself a quad core processor running at 3 Ghz he now in theory has a 12 ghz o processing power, Is this correct?

Only on EBAY

i bought my i7 and overclocked it, sometimes i do get near that massive ebay figure.

ie when i transcode blu ray structures all 4 [8 inc multi thread] do clock to 3.8 and run and run, it slashes the time taken by a single 3.8 core, in this situation you are seeing the 3.8x4 utilised for one user task

im not 100% sure on multi thread processors either
