DIFFERENCE BETWEEN CORE I3, CORE I5, CORE I7 !!!!!!!!!!!!

DIFFERENCE BETWEEN CORE I3, CORE I5,
CORE I7...?? 

 Core i3:

* Entry level processor.
* 2-4 Cores
* 4 Threads
* Hyper-Threading (efficient use of
processor resources) * 3-4 MB Cache
* 32 nm Silicon (less heat and energy) ->

 Core i5:

* Mid range processor.
* 2-4 Cores
* 4 Threads
* Turbo Mode (turn off core if not used)
* Hyper-Threading (efficient use of processor resources)
* 3-8 MB Cache
* 32-45 nm Silicon (less heat and energy) -> 

Core i7:

* High end processor.
* 4 Cores
* 8 Threads
* Turbo Mode (turn off core if not used)
* Hyper-Threading (efficient use of processor resources)
* 4-8 MB Cache
* 32-45 nm Silicon (less heat and energy)
