What Is a CPU?

Before diving into the juicy details of the CPUs, you need to make sure that you understand what a CPU means and what it does.

A CPU is short for “Central Processing Unit” and is also known as the processor. As the name suggests, it’s a crucial part of the PC system where it processes all the tasks on your computer.

It works by reading the functions stored in a certain program and executing these functions based on the instruction given by it. A PC processor will adjust, analyze, and control all the logic tasks that run when you’re using a computer.

In other words, it’s responsible for doing all the legwork thrown on it by other parts of the computer. As a result, having a more powerful CPU in terms of performance will mean a smoother overall experience while using the computer.

How to Read the Name of an AM3+ CPU

One of the critical points to understand how AM3+ CPUs is to learn how to read its name correctly. At the end of the day, all processors look technically the same for the untrained eye.

However, you can easily interpret a lot about the processor simply by understanding the way they’re named. Here’s how you crack the code!

Each CPU in the AM3+ series will have a technical name made of some letters and numbers. For example, an AMD FX-8350 or an FX-4300. The first part “FX” means that this CPU belongs to the FX series that’s produced by AMD.

As for the numbers, the first one represents the generation of a processor. For instance, FX-8350 belongs to the 8th generation while FX-4300 belongs to the fourth one.

As you might’ve expected, the newer generations of a processor usually have better features and provide better performance and processor powers. However, they usually cost higher as well.

The rest of the numbers within a model name describes other features of the process. For example, it may dictate the amount of power it can utilize while operating.

As a rule of thumb, the higher these numbers, the more powerful the processor will be. As a result, they usually cost slightly higher in return.

Why Buying an AM3+ Processor is a Great Idea

When AM3+ CPUs came out, they took the world by storm. Of course, one of their best selling points is their price tag.

AMD made sure that AM3+ is significantly more affordable than their rivals. Yet, the processors provide excellent performance in terms of capabilities and smoothness.

In fact, AMD is popular for its affordable options that are great for anyone’s budget. In fact, even AMD motherboards are also noticeably inexpensive. The best part is, AM3+ really didn’t compromise on the price.

Although AM3+ and FX series are now overshadowed by Ryzen AM4 processors, they’re still able to put on quite a show. In fact, benchmark tests show a tiny difference between them and Ryzen 3 for example.

To put it in the simplest way possible, AM3+ processors can provide you with a super solid performance as long as you have the right rig for it.

In other words, if you have a good combination of graphic card and RAM, you’ll be able to make the most out of this brilliant CPU.

What to Consider Before Buying an AM3+ Processor

Choosing the right AM3+ CPU means faster tasks, smoother gameplay, and more. For that reason, it’s crucial that you pay major attention to every aspect and detail about the CPU.

In the following section, I’ll provide you with an overview of these important points. This section will also help you build an image of the ideal CPU for your needs.

The Motherboard

Your CPU will fit into the motherboards’ socket. As a result, it’s important that you make sure that your motherboard can support the design of AM3+ CPU pins.

AM3+ CPU has a pin diameter of about 0.51mm that you need to make sure that your motherboard supports. Some motherboards might support backward compatibility, in which they’re able to support relatively older CPUs.

If your motherboard is too old for the processor, you might want to upgrade it. Also, you need to know that you can’t use AMD processors on an Intel motherboard.

Both Intel and AMD processors use different technologies and architecture while designing their CPUs and motherboards. So, if you have an intel motherboard, you either need to get an intel processor or replace the motherboard with an AMD one.

The Number of Cores

The first aspect that you need to decide about your AM3+ CPU is the number of cores it has. A CPU usually has more than one processor. Each one of these mini processors is called a "core", and it’s reasonable for working for specific tasks.

The more cores that your processor has, the more processes it can handle at the same time. Ideally, you need a processor that has at least 4 cores within the CPU.

These are called “quad-core” CPUs. However, if you’re looking for a multitasking beast, you should opt for octa-core processors that have 8 cores.

Clock Speed

Some people call it the CPU frequency. However, both terms describe the same thing and are measured in the same unit. Clock speed dictates how fast your CPU operates.

It’s measured in gigahertz (GHz) and increases as your CPU gets faster. A higher GHz CPU has a higher speed, so it’s able to complete the given task in a shorter time.

Each CPU model comes with different clock speed settings where the CPU can adjust its speed based on the different aspects. These aspects include the unit temperature and the type of task it’s handling.

Overclocking (Turbo Boost)

Each CPU has a base clock speed that describes the processes at its slowest speed. However, some CPUs allow you to “overclock” your process.

In other words, these ones allow you to push the speed of your CPU beyond its clock speed limits. This can be perfect for programs and games that are highly demanding in terms of processing power.

Overclocking a CPU must be dealt with caution, it might affect the lifespan of your processor if you aren’t careful enough. Also, if you’re going for an overclocking CPU, I recommend that you update your cooling system to avoid crashes and overheating issues.


The CPU cache is the amount of data that transfers at a time between the CPU and the Random Access Memory (RAM). the higher the cache, the more data transferring between the two parts at a time.

Cache capacity comes in 3 different formats. The L1 is the fastest but with the smallest space for data. The L2 balance between speed and space. Finally, the L3 will have the largest data storage but in exchange for being the slowest.


Some people confuse threads for cores. The reason behind that is that most CPUs have an equal number of cores and threads.

A thread describes the number of processes that your CPU can handle at a time. However, some processors have a multithreading feature.

This one allows the cores of your CPU to handle more than one action at a time. The most common one is a dual-thread core. This means that a multithreading 8 processor can handle up to 16 tasks at a time!

The Built-in Software

After you install the CPU to your motherboard, you should be able to install its software on your computer. This software is crucial to access some features and specifications of the CPU. For example, the software is where you usually overclock your CPU.

How to Install an AM3+ CPU on your Motherboard

Installing a CPU on your computer might sound like a complicated process. However, it’s quite simple if you’ve got everything right.

Before starting, you need to make sure that the CPU chip is compatible with your motherboard model.

To make things easier for you, you need to remove the motherboard from your computer and lay it on a flat surface.

Also, shut down your computer and unplug it from the wall for extra safety. Here’s what you should do:

  1. Open the sock lever that holds down the CPU in place
  2. Remove the old CPU if you’re upgrading
  3. Align the new CPU chip with the pins
  4. Gently push the CPU chip all the way in (it should feel like its clicking into position)
  5. Apply the thermal paste on the CPU

Now that the processor is in place, you can fit the cooler of your choice. You can easily apply the stock cooler that might come with the product.

The AMD cooler that comes with the process can easily fit your CPU chip. You’ll find a plastic cooler mount around the processor socket in the motherboard. You can fit in the cooler using the two nodules sticking out to hold the cooler clips.

You can also use a third party cooler if you want better performance and longer processor lifespan.

The Cooler Master Hyper 212 Evo CPU Cooler is one of the best coolers for the FX series. It also comes with all the wires needed for the task along with clear instructions on how to fit it.

Final Verdict

There you have it. A complete guide with everything you need to know before choosing the best AM3+ CPU for you.

As you can see, there’s a wide selection of options to opt for based on your needs. If you’re looking for an absolute beast of a CPU, the AMD FX-9590 is your way to go.
