General info

1.Supports 64-bit
Intel Core i7-4770K
Intel Core i7-4960X
Intel i7-3940XM Extreme Edition

A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit applications.

2.semiconductor size

22nm

Features

1.Uses hyperthreading technology
Intel Core i7-4770K
Intel Core i7-4960X
Intel i7-3940XM Extreme Edition

Many of Intel's processors use hyperthreading, which means that each core of the processor can work on two threads at once instead of most processors which work on a single thread per core. This means you can have significant performance gains in certain applications.

2.Has dynamic frequency scaling
Intel Core i7-4770K
Intel Core i7-4960X
Intel i7-3940XM Extreme Edition

Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.

3.Has AES
