Types of Central Processing Unit » All Types of Processors.

The acronym CPU is referred to as the Central Processing Unit. CPU is one of the most important parts of any digital computer or any other programmable device. Different types of central processing unit (CPU) is responsible for the efficiency and working of the device.

Before jumping into types of processors first understand the function of the CPU in simple terms.

What is the CPU and its Function?


The CPU is the central memory of the computer or any device that allows all the tasks like gaming, editing, Internet surfing, messaging, etc, to be carried out efficiently. The processor is placed in the centre of the motherboard around the VRM section.

In technical terms, the Central Processing Unit (CPU) is a vital component being the brain of a computer device that handles all the instructions and arithmetic or logical calculations.

And then signals are sent to the other units of the computer to carry out all series of processes related to the management of computer memory. During this process, heat generates which’s why small CPU fans need to install to dissipate it.

In short, the central processing unit is responsible for inputting and storing the programs and data that the machine will require at the time of executing a job as an output for the user.

How CPU works

The central processing unit houses the internal units like RAM and ROM memories, hard drives, power supply units.

These offers ports in which you can connect various input and output and storage devices such as monitors, pen drives, microphones, headphones, keyboards, mouse, digital graphics tablets, printers, and cameras via PC Cabinet.

Types of Central processing Unit / Types of Processors

There are 6 types of central processing units Single Core Cpu, Dual Core Cpu, Quad Core Cpu, Hexa Core Cpu, Octa Core Cpu, and Deca Core Cpu. These are the 6 types of central processing units that are being used in various devices like desktops, laptops, and mobile phones.

These types of CPUs decide the speed, Efficiency, Multithreading, cache, clock frequency, effective functioning of the computer, and mobile devices.

The performance at which software programs operate depends on how powerful the CPU is. The main manufacturers are Intel, and AMD in computers and Qualcomm (SnapDragon), MediaTek, Samsung (Exynos), and Apple Bionic are in mobile devices, each of them has its own type of Central Processing Unit.

Let’s get to know the list of different types of CPU processors and their features.

Types of Central processing Unit (CPU Processors)

1. Single Core CPU

The single-core CPU is the oldest type available and it was introduced in the early history of computing this was the only one that could be used in computers. It was possible to carry out certain tasks, but it was a bit slow.

Single-core CPUs can perform only one operation at a single point in time, that’s why they are not a very good choice at multitasking. This meant, at the time, a notable decrease in the performance whenever the user executes more than one application in them.

Although only one operation could be started at a time, another could be activated before the first was finished, but with each new operation, the equipment was slower. Also, the clock-speed of these processors was very low. And the performance, power, and speed of any CPU depend on its clock-speed.

Characteristics of a single-core CPU are very few compared to the latest cores for system operations. However, this was the beginning of a great revolution in computing.

2. Dual Core CPU

A dual-Core CPU is actually a single CPU, but it is comprised of two cores on the chip that’s why this CPU functions like two CPUs.

The clock speed of this processor also almost doubles make it possible to handle multitasking more comfortably and much better than processors that have only one core.

Dual-core CPU can execute more than one operation at the same time and at a higher speed. This means that only one operation could be started at a time, the second operation would be started a little before the first one was over. In this way, performance capacity and speed reduce a bit.

The dual-core CPU processor has to switch back and forth to different sets of data streams if more operation is to be done.

In order to use the full potential of Dual Core, it is necessary to have a special code written in the operating system called Simultaneous Multi-Thread Technology (SMT) so as to run programs more efficiently. Dual-core CPUs are faster than single-core CPUs, but not as fast as the four-core CPUs that have replaced them.

3. Quad Core CPU

The term Quad indicates the 4 cores present in the processor characterized by taking into account speed and power consumption, they also have great capabilities for multitasking in comparison to the single and dual-core CPUs.

It has four cores working simultaneously, capable of performing any task for which it has been intended, at high speed, and above all, performing several tasks at the same time. It is the immediate antecedent of what would later be the 8 or10 core CPUs.

The Quad-Core CPU divides the workload into four cores. This does not mean that it will multiple the speed four times for a single application. In fact, it will only accelerate multitasking work that means executing multiple tasks at the same time efficiently.

When you have to do a lot of work on a computer, like for Video Editing, Gaming, Designing, etc. then you use these types of CPUs with executing the SMT code will boost the speed more.

4. Hexa Core CPU

The Hexa Core CPU has six cores on the chip to execute the task and transmit all data more rapidly as compared to quad-core and dual-core processors. Therefore, its working speed, clock speed, performance will be faster and will also be more suitable for multitasking.

The first Hexa core CPU was launched in Intel core i7 processor in 2010.

5. Octa-Core CPU

The octa core CPU as its name suggests another multi-core processor are consists of 8 cores, which takes the performance and speed of multitasking to a different level than the above CPU processors for any computer device.

Numerous octa-core CPU processors comprise a dual set of quad-core processors that separates various activities between the different sorts that’s why it is also known as a “dual quad-core processor“.

Commonly, these types of CPUs are utilized to execute advanced tasks on computers and other devices.

6. Deca Core CPU

The dual-core is built with two cores, four cores are built-in quad-core, six cores are built-in hexa-core, eight cores are built-in octa-core, where Deca core comes with 10 cores where the Deca processors are developed with eight autonomous cores to execute a task will be much efficient and rapid than all the core processors until now.

It is the most powerful and successful CPU than the above CPU processors for any computer device. Now you would have a clear idea that on increasing the number of the core of the processors, the performance and its capacity to perform multitasking to increments.

Presently you would have a reasonable thought that on expanding the quantity of center, the presentation and its capacity to do performing various tasks to increments.

Deca core processors are the latest trending processor in the market. Due to its advanced features and performance, it is very successful in multi-tasking and for programs like 3d gaming, VFX, modeling, etc at the same time expensive in rate.
