The Restaurant Kitchen Revisited

Imagine three ways to make a restaurant serve more customers faster: 1) The chef works faster (clock speed - more cycles per second). 2) Hire more chefs working at the same time (cores - parallel processing). 3) Keep frequently-used ingredients right next to the cooking station (cache - faster data access). Modern CPUs use all three strategies to maximize performance!
