What are the Cores in the CPU? How Many do you need? Complete Guide

The kind of software you can run and the number of programs your PC can handle at once are directly influenced by these components. You can save time, frustration, and money in the long run by planning ahead for your computing requirements. However, it can be challenging to precisely determine the number of cores required for optimal functionality.

What are the Cores in the CPU?

We explain how many CPU cores are required for various computing tasks and how to select the best CPU for you in this guide. However, keep in mind that the number of cores is only one aspect to consider when selecting the best CPU for your computer. The clock speed of your cores should also be taken into consideration. Our HP Tech takes article on CPU clock speed can be found here. Before you start shopping, it’s helpful to know how many CPU cores you need to run basic programs or get the most power out of your new laptop or desktop PC.

What are a CPU’s Cores and why do we require them?

Your computer’s central processing unit, also known as the CPU, is responsible for executing applications and sending instructions to the RAM (random access memory) to retrieve data. The pathways that a processor’s billions of tiny transistors use to function are known as CPU cores. To properly complete a task, anyone interested in multitasking will require at least two cores.

The processor of a CPU is a core (opens in a new tab). In the past, each processor only had one core that could concentrate on a single task at a time. CPUs today have between 2 and 18 cores, each of which can perform a different function. That can have a significant impact on performance, as shown in our CPU Benchmarks Hierarchy.

When exploring the concept of CPU cores, it’s important to consider the compatibility of the processor with your motherboard. One crucial aspect to determine compatibility is the motherboard’s socket type. To ensure you have the right CPU and maximize its performance, it’s essential to know how to find and check your motherboard’s socket type accurately. You can refer to a comprehensive resource that provides valuable insights on ‘How to Find and Check Your Motherboard Socket Type?‘ This resource offers step-by-step instructions and practical tips to help you identify the socket type of your motherboard with confidence.

A CPU is more efficient the more cores it has, as one core can work on one task while another core works on another. Some laptop CPUs (also known as mobile CPUs), like Intel’s 8th Generation processors, have four cores, whereas many processors, particularly those found in laptops, only have two cores. If you can afford it, you should aim for at least four cores in your machine.

A process known as simultaneous multithreading or, in the case of an Intel processor, Hyper-threading, both of which mean the same thing, can be used to divide a core into virtual cores known as threads. The majority of Intel CPUs with two cores use Hyper-threading to provide four threads, while AMD CPUs with four cores use simultaneous multithreading to provide eight threads.

Multiple threads are better utilized by some apps than others. Games, for example, don’t benefit from having a lot of cores, but most video editing and animation applications can run much faster with more threads.

Multi-core is a popular hardware buzzword because processors from AMD and Intel now have more cores than ever before. They’re fun, especially in the gaming world, but are they necessary? We look at exactly what multi-core processors do and whether or not they can really help your company.

What is a processor with multiple cores?

A computer processor with two or more separate processing units (CPUs) known as cores reads and executes program instructions as if the computer had multiple processors is known as a multi-core processor. The CPU’s performance in a single-core processor is limited by the amount of time it takes to communicate with RAM and cache. Waiting for memory access results consumes approximately 75% of CPU time. Manufacturers have been releasing more multi-core machines to boost processor performance. The performance of a CPU with multiple cores may be significantly superior to that of a single-core CPU of the same speed.

Multi-core processors might also be right for you if your company deals with virtualization, databases, and the cloud. All of these events must function by switching between each process using a single core. For these instructions to function without jitter or extremely long processing times, multi-core processing is necessary.

In general, a multi-core processor is preferable if the application supports it. A typical computer user only needs a processor with four or two cores. Even though most users and business owners won’t see any real benefits from using four processor cores because there isn’t enough non-specialized software to use them, many business computers now come with these as standard.

How many cores of the CPU do I need?

Resources are needed for different computing tasks. The number of cores you have is the most important determinant of whether or not programs will run smoothly. Your device needs multiple CPU cores if you want to run multiple apps at once or programs that use more resources.

How many cores of the CPU do I need

However, the majority of standard-tier laptops have two cores, so if you just want to create text documents, browse the web, or do other basic tasks, your basic models should have them.

1 CORE: It’s hard to find a computer with just one core in today’s world. You won’t be able to open more than one program at once if you only have one.

2 CORES: The majority of budget users prefer dual-core processors. Without overburdening your system, you can access email, create and edit spreadsheets and documents, and listen to music. However, you won’t be able to render or edit video without crashing your system. Also, many games can probably be played on lower settings, but if you really want to play games, you should think about getting a quad-core processor.

4 CORES: In addition to all of your regular work or school responsibilities, quad-core CPUs enable you to render video more slowly or play games at lower resolutions. As long as you are not playing the most processor-intensive games and have a dedicated GPU, most gamers will be fine here. On the other hand, if you work in video editing, graphic design and 3D rendering, sound editing, or a related field, more cores would be more helpful. Applications for these sectors need to use more processing power, have features like a dedicated GPU, more storage, and at least 16GB of RAM.

6 CORES: All of the aforementioned tasks can be completed with Hexa-core processors, as can more complicated software for editing video and audio. This is a good option for games and programs with more advanced features because it lets you run multiple programs at once. With six cores, most streamers will be able to stream games and run them, while those who work with other media will have plenty of power.

8 CORES OR MORE: Octa-core CPUs are great if you’re an engineer, a video editor, or a professional gamer. For maximum power, video gamers who play, record, and stream a lot of games should choose more cores. Additionally, this is your sweet spot if you frequently utilize power-intensive software like AutoCAD or VR.


We learned about the differences between a CPU and a processing core in this article. We began with a brief discussion of the development of processing units. Therefore, in order to comprehend their primary components, we investigated the concept of a processing core. In a similar vein, we examined the CPU’s concept and primary components. Last but not least, we reviewed the CPU’s processing cores and compared their similarities and differences.

Knowing the processor’s number of cores is essential when purchasing a new desktop or laptop computer. Two or four cores are sufficient for the majority of users, but video editors, engineers, data analysts, and others working in related fields will require at least six cores.

Processing cores and central processing units (CPUs) are not the same things, as we can see. A CPU is in charge of controlling the cores and connecting data from other components of the computer system to them, whereas cores actually perform tasks. As a result, a processing core operates within the CPU and relies on another to carry out computational tasks.
