Intel core 2 duo proccessor?

Question

Let's say that you have a computer with a 2.2 ghz. core 2 duo processor. Does that mean that both cores are running at 2.2 ghz., giving you a total speed of 4.4 ghz., or that each core is running at 1.1 ghz? I really need your help, thanks.

Answer 1

You have two cores running each at 2.2Ghz. This does not mean a total "speed" of 4.4Ghz. It means each core runs at 2.2Ghz, meaning if you have two things running, each one will have a core working on them at 2.2Ghz, as opposed to having to share one 2.2Ghz core. You can't multiply by 2, or by almost 2, or by 1.5, or any other number that these other people will tell you.

Answer 2

You have two 2.2 GHZ cpus running at up to 50% untilization each. The reason they are faster is that they run multi-thread instead of single thread. It's not 2X2.2 or 1.5X2.2--its 2.2!

Answer 3

Sigh.

Each core runs at 2.2 on it's own. The total combined speed isn't going to be exactly 4.4. But it will be close.

Answer 4

The general rule of thumb with dual cores is speed X1.5 = true cpu power.

so a 2.2 would equate to a 3.3

But - if you went to the 2.4 E6600 it has a larger L2 cache so it would appear to run faster.

The lower end C2D have a 2mb L2 cache while the 2.4 and up have a 4mb L2 cache. This helps alot.

Answer 5

2.2 gh x 2 cores = total speed of 4.4gh

each core is running at 2.2 gh total is 4.4 gh
