ELI5: Computer processor. How do I compare dualcore to quadcore? For example, is 2GHz dualcore equivalent to 1GHz quadcore?

Something just doesn't seem right about straight multiplication.

Simple analogy: think of a core like a lane on a highway, and think of the clock speed as the speed limit.  Two cores would mean there are two lanes on the highway.  

Now, let's define a couple of systems.

* System A: single core, 1 GHz (30mph, one lane)

* System B: dual core, 1 GHz (30 mph, two lanes)

* System C: single core, 2 GHz (60mph, one lane)

* System D: dual core, 2 GHz (60mph, two lanes)

For a single car on a route, then, A and B are basically equivalent, as are C and D.  The extra lanes don't matter, so the 60mph road is going to be faster.

Now put 100 cars on the route.  Suddenly, system D is looking a lot faster than the others.
