* 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)
