Diffrence Between Core i3, Core i5, Core i7 Processors

Intel has stopped selling Core 2 Duo. Core is the new range of Intel processors Named Core i3, Core i5, Core i7 Processors. So we should know the diffrence Between them : -

 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)
hope you find the info good...!!
