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

Core i3:
1) Entry level processor.
2) 2-4 Cores
3) 4 Threads
4) Hyper-Threading ­ (efficient use of processor resources)
5) 3-4 MB Cache
6) 32 nm Silicon (less heat and energy)
.
Core i5:
1) Mid range processor.
2) 2-4 Cores
3) 4 Threads
4) Turbo Mode (turn off core if not used)
5) Hyper-Threading ­ (efficient use of processor resources)
6) 3-8 MB Cache
7) 32-45 nm Silicon (less heat and energy)
.
Core i7:
1) High end processor.
2) 4 Cores
3) 8 Threads
4) Turbo Mode (turn off core if not used)
5) Hyper-Threading ­ (efficient use of processor resources)
6) 4-8 MB Cache
7) 32-45 nm Silicon (less heat and energy)
