What are the Differences between i3 and i5 processor? The i3 and the i5 processors belong to the same family Intel Core family. Like the others the i7 and the i9.

Intel Core code name “Yonah” is used for both desktop and laptop computers. The processor is also known as the CPU or the Central Processing Unit of the computer and its components.

The job of the processor is to take input and to give output to the user. It is one of the most prominent components of the computer.

It is also known as the most important IC or the Integrated Circuit chip attached to the computer.

Just like the brain, the processor interprets and understands the commands given by the user to the computer.

It can perform various functions and the latest processor can do even more than the older processors.

It even takes care of the movements of the mouse and the keyboard. Processors are used in many devices like desktop computers, laptops, and even mobile phones.

Many neglect the other Processing Units. And only think that the CPU or the Central Processing Unit is the main processor of the computer. The CPU is not the only processor.

One can even find the GPU or the Graphics Processing Unit there. Processors here consist of cores. One processor may have many cores. These cores work together.

Nowadays, in the market, processors come with more than two cores. Like the Quad Core having  4 cores, Hexa Core having 6 cores. And even the high end computers come with 8 cores or Octa Core processor.

The processors first take or receive information or command. Then it translates the command for the other parts of the CPU to understand.

Then work on the command to give a write back to the system which has given the command. Most laptop computers because of the small size and portability have microprocessors in them.

The latest processor comes with many cores or multi cores. Intel manufactures processors that come with many cores. The i3 and i5 processors are developed and manufactured by Intel.

They both can be used in desktop and laptop personal computers. Belonging to the “i” series and the Intel family. These two processors are seen as midrange processors.

And their prices are somewhat the same. Many find it difficult to choose between the two because many cannot differentiate the task they want to perform.

The purpose of choosing becomes quite different. Like if someone wants to do an intensive task, while some want to do regular tasks.

Playing games and photo editing also falls under the preference when one chooses a processor. Since both are seen as a mid-range processor.

The i3 processor is seen as lower than the i5 processors. It is because the i3 processor has a lesser number of cores compared to i5. It mainly consists of two cores and the higher end ones have four cores for the desktop computers.

On the other hand, the i5 processor comes with Quad Core or Octa Core processors. It is even known as the mid range processor. Better for gaming and intensive tasks.

So now it depends on the user’s budget, utility, and preference whether to choose i3 or i5 processors. Because both come with a lot of benefits and drawbacks.
