Features

1.Uses hyperthreading technology
Intel Core i7-3940XM
Intel Core i7-4770K

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 i7-3940XM
Intel Core i7-4770K

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
Intel Core i7-3940XM
Intel Core i7-4770K

AES is used to speed up encryption and decryption.

4.Supports hardware-assisted virtualization
Intel Core i7-3940XM
Intel Core i7-4770K

It is easier to obtain better performance when using virtualization if it is hardware-assisted.
