General info

1.semiconductor size

14nm

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

Best

AMD Ryzen 5 2500X

12nm

2.GPU clock speed

350MHz

The graphics processing unit (GPU) has a higher clock speed.

Best

Intel Core i7-4770R

1300MHz

3.Supports 64-bit
Intel Core i5-6400

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.

4.thermal design power (TDP)

65W

The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.

Best

Intel Atom E3805

3W

5.Has integrated graphics
Intel Core i5-6400

With integrated graphics you don’t need to buy a separate graphics card.

6.DirectX version

12

DirectX is used in games, with newer versions supporting better graphics.

Features

1.Has AES
Intel Core i5-6400

AES is used to speed up encryption and decryption.

2.Has dynamic frequency scaling
Intel Core i5-6400

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

3.Uses hyperthreading technology
Intel Core i5-6400

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.

For example

Intel Core i7-9800X

4.Supports hardware-assisted virtualization
Intel Core i5-6400

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

5.Has NX bit
Intel Core i5-6400

NX bit helps protect the computer from malicious attacks.

6.Has F16C
Intel Core i5-6400

F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
