Depends on the application. If you are doing alot of multitasking (running many programs at once) then a multi-core will be a good option. CPU clock speed is relative in this because it is common knowledge that a good dual core processor can outperform quad cores in gaming at times. This is because most games out now do not utilize the 4 cores. So in conclusion it really depends on what you want to do. For gaming, a dual core is a good option, for heavy multitasking a 4 core may be good for you.
For eg, some games does not support multiple cores then the hertz is more importain while if ur working with photoshop or some graphic software the cores are more importain.
It is of no importance at all to the average computer user. All it tells you is the clock that the machine runs on and there are many other variables (both hardware and software) that affect the actual performance of the computer in actual use on real world problems. Without accounting for these variables, processor speed will be very misleading. For many people processor speed is important as a "boasting number" so that they can claim to be better than another person!
There is more to it then that. Some processor's that have a speed of 3.0GHz can process less data then one that is 1.7 GHz. To answer your question, because you could spend a thousand dollars and get a slower computer then one for 700.00.
It's the model number.
Most people will tell you that it is impossible to answer this. First of all, there is no notion of "fastness" in computer chips. You may be asking about the highest clock speed on a processor, but that number means little by itself when it comes to performance (which is the important factor). Second, if you were to ask about the best performing processor, then you need to devise some fair way of measuring the performance of each. And finally, even if you could definitely say which chip is faster or better between a pair of chips, the "fastest" or "best" would change constantly, and so asking something like this has little meaning.
The GHz is the clock frequency. It is important for processor speed but the number of kernels is even more important as each kernel can do processing independently from the others.
An address bus carries address information. It is important because the number of lines in it tells the maximum number of memory addresses. It balances speed.
The speed of a computer is a lot of things. The speed is how fast your computer can get data off your Hard Drive, How much Ram or Memory you have, and how fast your processor is. Most people say that the speed is the number on the processor. But That is not always true.
Your computer's central processing unit (CPU), also known as a processor, can be thought of as the brain of the computer. Fast processors typically offer better performance than slower processors, and they are especially useful for running multimedia programs, such as games or audio and video editing programs.A computer's processor speed describes the maximum number of calculations per second the processor can perform, and is given in megahertz (MHz) or gigahertz (GHz). Generally, the larger the number, the faster and more powerful the processor.Under System, you can view the processor type and speed, as well as the number of processors installed, if your computer uses multiple processors.Older computers and some netbooks still have speeds in MHz (Megahertz). These speeds may be doubled if the computer has more than one processor, or the processor has 2 or more cores.To find out the speed of your computer running windows,Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking System.For Mac users, click the Apple logo and click "About This Mac".
At the heart of every computer is one or more processors. While some hand held devices like mobile phones have the processor fixed to the main circuit board there are computers that allow you to change the number and speed of the processors in the computer. This versatility is done by fixing the processor to a business card sized card. This card is called a processor card
Check the manufacturer's Web site where you bought it and enter in your model number.
Th clock speed is the processor speed. It is simply the amout of operations the processor can do per second. However if the processor has multiple cores, it will be as fast as number of cores * clock speed. Note that the processor speed is not the overall computer speed.
Every computer must have a processor to do the work. To build a micro processor means assembling a large number of transistors, capacitors, and resistors into a small package
