it depends on the cpu. I program microcontrollers that have as few as 8 pins, cpu's on motherboards have many more as they are required to interface with external devices such as memory busses. usually in excess of 200. more modern processors don't have pins, they have contact points which meet contact points on the mainboard. pins are a relative point of discussion but not necessarily factual.
