General info

1.Supports 64-bit
Intel Core i7-3770K
Intel Core i9-7940X

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

14nm

A smaller size indicates that the process to create the chip is newer.

Features

1.Uses hyperthreading technology
Intel Core i7-3770K
Intel Core i9-7940X

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 i7-3770K
Intel Core i9-7940X

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 i7-3770K
Intel Core i9-7940X

AES is used to speed up encryption and decryption.

4.Supports hardware-assisted virtualization
Intel Core i7-3770K
Intel Core i9-7940X

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

5.Has Tri-Gate transistors
Intel Core i7-3770K
Intel Core i9-7940X

An advanced transistor technology developed by Intel that allows lower power consumption and higher speeds.

6.Has MMX
Intel Core i7-3770K
Intel Core i9-7940X

MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
