If a dual core processor has a speed of 1.86Ghz, do you double it because it is a dual core?

Answer 1

Dual CPU or dual core systems do not "double" in the sense that I gather you are asking. Each processor is capable of processing information but the applications running on the system must be designed to run on multiple processors using a concept called "threading". Not all programming task are suitable for threading so they can only use a single processor. The applications that can take advantage of multi-threading will have a performance increase but the management of the threads will require some level of overhead (i.e. if processing data on multiple threads, the data must be broken down for each processor, processed, then reassembled). So a multi-core or multi-CPU system isn't going to "double" as you might think. You will see improvements in performance though if running multiple applications (i.e. virus scanner and a game - each taking a CPU and not competing for processor time, although still for disk access and other system resources).

Answer 2

The easiest way to understand it is to think of a single core processor as a 2 lane highway and a dual core as a 4 lane highway, the speed is still 65mph but it can handle twice as many cars.

Answer 3

it depend on what you are trying to do.
in plain english, if it is word procesing, having a dual core is useless.
dual core processor are for heavy jobs.

let's put it this way. let's think that you and a friend work in a restaurant cooking. if you have to prepare a meal for 1 person , one of you can handle itwhile the other does nothing. but if you have to cook for 20 people you are going to need help, so both of you have to work together to keep up with the work.
is it clear? i hope so.

Answer 4

No, doesn't work like that and even if you could hack it to do so (involving liquid nitrogen) you'd burn the chip and board out in a VERY short time.

The accepted norm is to overclock by 10%. That say, slower labelled chips tend to be more overclockable. Rule of thumb, the faster it is the less you have to work with.

Answer 5

Nope, doesn't work like that sadly.

It won't be twice as fast parse, it will just be able to do two things at once.

Hmm, easiest way to describe it really.

Answer 6

No.

The way I understand it is that you have two processors that run at 1.86 GHZ.
