All about CPU cores: what they are, how they work and their types

Before purchasing any processor, one of the things you should pay attention to the number of cores.

Together with the other characteristics such as architecture, generation and others, it becomes one of the most important factors because it determines performance.

Among so many types of CPUs that exist, it is easy to get confused. That is why it is essential that you know very well how cores workas they can make a big difference when running video games and applications.

What are the cores of a CPU?

Surely you have searched for a processor model and you have realized that the number of cores is specified which has as a characteristic.

This is information that you should consider before purchasing said component, since it is an independent processing unit What is incorporated into the CPU chip?

In this way, each of the cores is responsible for carrying out actions individually so that different actions can be carried out in order to maintain adequate performance.

Due to these they are able to determine the number of tasks a team can do simultaneously, so the more cores it has, the greater the capacity.

Initially, this type of components had a single core, but over time the technology has evolved to create multicore processors to adapt to demands of new software.

How cores work

The operation of the cores of a CPU consists of following a cycle of instruction which goes hand in hand with the requests that the chip receives so that they can be executed correctly.

This process is broken down into various stagesgoing through the fetching of the instruction from memory (Fetch), the decoding (Decode), the execution of the instruction (Execute) and the result being recorded in memory (Writeback).

Once these phases are completed, the cycle is finished and the action is effectively completed. When a CPU has several cores, each of them must do one of the steps individually, dividing tasks to make it the fastest process and thus there is greater performance.

What type of CPU cores are there?

As already mentioned, the evolution of the CPU goes hand in hand with technology of the nuclei.

For this reason, there are multi-core processorssince this way they have the ability to perform more actions at the same time.

Nowadays, it is crucial to know exactly the amount of these elements, regardless of whether you have Windows or Linux.

These are the ones that give you the possibility of know whether or not you can run apps and video games of the latest generation on the PC or consoles such as Xbox Series X|S and PlayStation 5. To be more specific, they are the following:

• Single-core: It has a single core, being able to do one task at a time, making it the slowest and least powerful of all.
• Dual-core: two-core and better than the previous one, but still low-end.
• Quad-core: It means that the CPU has four cores, being one of the most common in mid-range computers and mobile phones, since they maintain acceptable performance in applications.
• Hexa-core: six cores. Mostly used for existing apps and multitasking actions.
• Octa-core: eight cores, which is also frequently used in PCs and smartphones due to its high-performance power.
• Deca-core: ten cores. While less common, high-end devices typically have this type of high-powered processor for extreme overall performance.
• Dodeca-core: It has twelve cores, being one of the most powerful and normally used in workspaces or servers for complex actions.
• Hexadeca-core: Being sixteen cores, it is typically used in high-capacity servers or applications that handle many multitasking requests.
• +Hexadeca-core: There are CPUs with more than 16 cores, such as those with 24 and 32, but only on special occasions, as incredibly demanding actions would be required, since it is the most advanced amount to date and larger numbers will surely be seen in the future.

From the list, the most common in computers today are quad-core, hexa-core and deca-core.

Special features are sometimes added to these types, such as Intel hyperthreadingwhich offers additional efficiency by allowing cores to handle thread executions.

With all this information, you will surely prepare very well to decide which will be your next processor and What type is worth investing your money in?.

Both Intel and AMD have a variety of series from different ranges where you can choose the most suitable model for you.
