The speed of the front side bus is often used as evolution of processors pdf important measure of the performance of a computer. Intel opened its FSB CPU socket to third party devices.

Intel had very closely guarded who had access to the FSB, only allowing Intel processors in the CPU socket. Different CPU speeds are achieved by varying either the FSB frequency or the CPU multiplier. Setting an FSB speed is related directly to the speed grade of memory a system must use. The memory bus connects the northbridge and RAM, just as the front-side bus connects the CPU and northbridge. Often, these two buses must operate at the same frequency.
