The Ultimate Guide to Choosing a CPU

A CPU is often referred to as the brain of a computer since many believe it thinks like a human brain. Rather than referring to the CPU as a calculator, it would be more accurate to refer to the software as the “brain.” Without software, a CPU would be limited to calculating.

Types of CPUs:

There are six types of central processing units:

1. Single-Core CPU

In the early history of computing, single-core CPUs were the only type of CPU that could be used in computers. Specific tasks could be completed, but they were a bit slow.

Since single-core CPUs can only perform one operation at a time, they are not very good at multitasking. At the time, this meant that when the user executed more than one application in them, the performance decreased significantly.

2. Dual Core CPU

Dual-Core CPUs is one CPU but have two cores on the chip, so they behave like two CPUs simultaneously.

This processor’s clock speed also doubles, making it easier to multitask than processors with just one core.

3. Quad Core CPU

Compared to single and dual-core CPUs, Quad Core CPUs are characterized by their ability to multitask, speed, and power consumption.

Having four cores, it can perform any task at high speed and, above all, perform several tasks at once. A CPU with 8 or 10 cores is its immediate antecedent.

4. Hexa Core CPU

Compared to quad-core and dual-core processors, the Hexa Core CPU has six cores to execute tasks and rapidly transmit data. Therefore, its working speed, clock speed, and performance will be faster and more suitable for multitasking.

5. Octa-Core CPU

As its name implies, an octa-core CPU is another multi-core processor with eight cores capable of multitasking at a higher speed than any of the CPU processors listed above.

Most octa-core CPU processors contain a dual set of quad-core CPUs with various separate activities, which is why they’re also called “dual quad-core CPUs.”

6. Deca Core CPU

There are two cores in dual-core processors, four in quad-core processors, six in Hexa-core processors, eight in octa-core processors, and ten in Deca core processors, which are developed with eight autonomous cores. As a result, the Deca processors will perform tasks more efficiently and rapidly than all other processors until now.

Pros and Cons of a Used CPU purchasing:

There are several pros and cons to buying a used desktop computer. The main advantages are the general cost, the ability to find great deals, and the possibility of extra hardware or software. One of the main disadvantages is the potential for damage, scams, or stolen computers and the lack of a transferrable warranty. When purchasing a used desktop computer, buyers should conduct thorough research to ensure high quality, fair pricing, and legality.

Many buyers find used computers very appealing because of the significant cost savings they can achieve. Those who cannot afford a high-quality new computer can save money by finding a used desktop computer of equal quality. Individual previous owners often sell used computers rather than retail outlets, so there is no overhead, further reducing costs. Used computers often contain additional hardware or software purchased and installed by their previous owners, adding to their overall value.

How to choose a motherboard:

One component will serve as its foundation, whether you build your own PC or buy a pre-built PC that you might want to upgrade later. The motherboard is one of the most critical components of a PC. Many other components will be determined by it, and, at the same time, some other choices, such as the Decide which motherboard will work with the processor you’re going to use in your new PC. Here is what you need to consider before you buy:

Form Factor:

The first step is to choose a form factor. Micro ATX motherboards are also standard (although they are smaller and have fewer expansion slots).

Processor Socket:

The next step is to choose a processor socket after choosing a form factor. Different sockets have been used, but only three are applicable today. There are three types of connectors: LGA, PGA, and BGA. AMD uses PGA, while Intel uses LGA.

RAM (Random Access Memory):

RAM stands for Random Access Memory. The motherboard you buy determines how much and what RAM you can have. As a result, it’s essential to consider this before buying a motherboard.

PCI Slots:

A PCI slot is a connection or port on a motherboard. For years, they have been the standard expansion slot, allowing expansion cards to be connected. Consider whether your motherboard has the slots you need based on how you plan to use your computer.


When you buy a motherboard with built-in features, you don’t have to worry about buying extra expansion cards. Most motherboards come with onboard audio as a standard feature.


You may need to consider the number of SATA ports you need when purchasing a motherboard. SATA ports allow you to connect optical drives and storage drives, such as SSDs and HDDs. Make sure your motherboard has all the SATA ports you need for all your drives.

Choosing a Graphics Card (GPU):

Here are some of the most common terms you will hear and what they mean regarding choosing a graphics card and your machine’s performance.

  • Memory: Your GPU features RAM (Random Access Memory). For 1080p gaming on high settings, you should have cards with at least 4GB of memory.
  • Memory Speed: A graphics card’s bandwidth or memory speed determines how fast it can process data. This is because cards can have the same amount of memory but at different speeds, which can result in significantly different performances.
  • Power Connection: Almost all dedicated graphics cards require more power than a PCIe slot can provide. A 6- or 8-pin power connector directly connects the PC’s power supply to the GPU.
  • TDP: TDP, or Thermal Design Power, is a specification that measures how much power a GPU draws and how much heat it generates.
  • Size: Your graphics card’s size is essential for many reasons, sometimes called the form factor. This is primarily due to the GPU needing to fit in your case.


When you understand your utilization and how to choose a CPU based on your usage, choosing the best CPU is a simple process. You should first consider the intended use of the CPU before determining your budget based on the other components you will need. Even though CPUs are vital, combining a fast chip with subpar graphics or a mechanical hard drive that rotates slowly (unless you don’t play games) makes little sense.

Most people recommend AMD only to those on a restricted budget, which is accurate but incomplete. AMD dominated the processor market in 2016 when its Ryzen line was introduced. With AMD processors, Intel’s closest rivals are now beaten in almost every benchmark, including gaming, where AMD routinely beats Intel.
