The Memory Bus


The memory bus is actually the major limiting factor to overall system performance. Older motherboards had the processor running at the same speed as the memory bus, but the more recent boards have the processor running at 2, 3 or even more times the speed of the memory.

The more that the processor is running faster than the memory, the more often it will have to be on standby waiting for information from the memory. This is why the system cache is very important, because it is much faster than the main memory, which means the processor can do more useful work and spend less time just waiting.
