What is the difference between duo core with dual core?

Now, many people are made confused by actual difference between Intel Core Duo and Dual Core. Which is faster? which is cheaper? which is better processor? etc..etc..etc....

Next, I will explain differences both processors as short as possible:

Actuallly both processors have the same core speed, but Dual Core is 50% smaller in L2 cache than Core Duo:
  • Core Duo: L2 Cache = 2 Mb
  • Dual Core: L2 Cache = 1 Mb
So, Core Duo is better than Dual Core, because have bigger L2 Cache and bigger FSB.
