motherboard?

Question

I saw a computer motherboard with 2 processors why is that?

Does that mean its much faster than one with just 1 processor?

Answer 1

Yes, this will. It doubles the processing power. But not alone processing power is responsible for a net high speed. The amount of primary memory, bus-speeds and response time of involved peripherals ---- all have to contribute to a net speed.

Today's multitasking system make use of multi-threading. A thread is a process that runs on a single processor concurrently with other threads. For example, in a word processing application, one thread is providing you with editting facilites, while at the same time the other one is checking your spells and grammer.

Suppose at certain time instance, there are 16threads running in a system with one processor, the single processor has to accomodate all 16threads by allocating a time slice to each of them. so every thread (generally speaking) takes 1/16 of total time. Consider the same workload for two processor (generally speaking), each processor has to accomodate 8 threads thus giving each thread 1/8 of total time. More time given to a thread will obviously speed it up.

There are so many complex technical issues involved, I overlooked many of them just for the sake of simplicity.

If you are keen to know more about it, search the internet for "multi-processing systems". Hope that answers the question.

Answer 2

Yes 2 processors are fast than one. In one u have millions of circuits in one silicon chip. When you have 2 the capacity doubles and so the computer's speed turns faster. 2 processors are called Duo Core from Intel

Answer 3

Yes, because you can have 2 processors with each one having 2 or 4 processors on each chip. So you can get 4 or 8 cores of proccesing power. I think the only operating system that supports this is macintosh or some form of Linux.

Answer 4

Lol, why yes two processors are better than one. But in all reality its made for multi-processing applications, people who play extense games and video edit, with 2 processors if gives you two cores to work from instead of just one that would cause lagging. So, Two processors give you the extra girth to play those really dirty games. =)

Answer 5

Dual CPUs are intended for server applications not desktop PCs. The operating system has to be capable of supporting symetrical or parallel processing to make use of dual CPUs.

To the best of my knowledge, neither XP or Vista can do that.
