When performing a desktop processor comparison do keep in mind that the processor is one of the most important components of a desktop as it essentially acts as the brains of the computer. How fast you can download files, how many applications you can run at one time, and how quickly your browser can load images and web pages are all largely determined by the brand and model of processor your computer has.
In general the higher the CPU(central processing unit) speed the higher the performance of the desktop computer. There are two processor speeds to pay attention to. The first is the speed at which information is processed(clock speed). The second is the speed at which the CPU communicates with memory and the graphics processor(via Front Side Bus).
A desktop processor comparison is not complete without explaining
