How Do I Choose the Best CPU?

Who are you? What do you do for a living? What important tools do you use at work? What do you do for fun? For most people, the answer to at least one of these questions will involve a computer of some sort. As the years go by, we see computers becoming more and more influential in daily living.

Almost everyone has one form of personal computer or another in their homes or offices. While some may not spend all their time at their computers, there are those that do. These people may be earning their living this way, requiring that they get a laptop so they can keep working wherever they are. Others might just watch movies, or they could be hardcore gamers on their gaming desktops. Whatever the case, a great percentage of us spend a lot of time in front of a screen.

Most of the people who require heavy processing for gaming or programming can attest to the frustration that can occur when their computer isn’t working correctly. What determines the performance of your computer is the CPU, or central processing Unit.

A CPU is one of the more integral parts of a computer system, and it plays an important role in determining the overall speed and performance of the system. This is why it’s necessary to have the most suitable one for your everyday needs. Trying to work on a slow or erratic computer system is a pain that many have known, so having a well-working CPU can reduce a lot of the daily frustrations you may experience.

In this guide, we’ll help you in your search for the perfect CPU. What’s the perfect CPU, you ask? It’s the one that has all the features you require for work, gaming, or just daily use, and one that falls within—or even below—your budget! Depending on your needs, you may also want to check in to getting a CPU cooling fan as well.
Price
Before deciding what to buy, it’s always important to consider the price of the product as well as your own budget. In our research, we found CPUs that can be purchased for as low as $70, and ones that can cost as much as $600. The price will be determined by factors like the CPU’s clock speed, number of cores, and the presence of a cooling fan.

While this range does not cover every price possibility—some are more expensive and some are cheaper—be careful of cheap CPUs. If you don’t use your computer much, or if you only need it for just a few things like email and printing, you might be able to get away with purchasing something cheaper. However, if you need your computer for work, school or just relaxing, investing in a quality CPU is a good idea because then you won’t have to spend money on another CPU later.
Features
Before buying a CPU, it’s important to be know what you need. Computers are complex, and finding a CPU that properly fits your needs can be difficult if you don’t know what features to look for. While any given CPU can have a myriad of features, we have taken the time to highlight the ones that require the most consideration before purchase.

Here’s our list:
  • Clock Speed
  • Max Turbo or Overclocking
  • Number of Cores
  • Number of Threads
  • Cache Memory
  • Cooling System
  • Noise level
  • Energy Management
Now, let’s take a closer look at what these features mean.
Construction and Design
A CPU’s clock speed basically determines how fast it can perform. It also determines how many programs you can run at any one time without slowing the entire system down. A good clock speed will be able to run all your necessary programs smoothly and efficiently. As a general rule, a higher clock speed is usually better.

A computer’s speed is especially essential for gamers or people that run demanding programs, like 3D modeling. They usually require as much speed from their systems as possible. This is why some CPUs also have a max turbo, which is a clock speed beyond a CPUs regular speed. It can be made to reach this speed through certain processes like overclocking. Overclocking puts strain on your system, but this is accounted for in some CPU designs.

The number of cores possessed by a CPU is usually a huge determinant of its overall speed and performance. A higher number of cores means that a CPU can handle a larger amount of tasks at the same time. The number of threads present in a CPU also determines its performance and speed. Similar to cores, each thread translates to further proficiency at handling multiple tasks. For users that run several programs at once, a CPU with a higher number of cores and threads is best to ensure continued smooth operation

A CPU’s cache memory is a temporary record of all program instructions within a system at any one time. It can be viewed as a list of all the things your computer needs to do at that very moment. A CPU with a cache memory that’s too small might end up delaying your programs and processes, so go for a lightly larger one.
Performance and Ease of Use
CPUs can generate a lot of heat, which can be harmful to the system if it starts to reach a very high temperature. Cooling systems help control heat output, and you can find them as fans or as liquid systems. If you plan to really push your computer to the threshold of what it can do, buying a separate cooling fan to avoid overheating isn’t a bad idea.

During operation, CPUs can be noisy, especially if something isn’t fitting correctly, or if the system has been put through a lot of abuse. Some Typically, a CPU should be fairly quiet, but you may want to look for one that’s designed to reduce noise if you don’t like to hear it humming.

You may also want to look at how much energy a CPU will consume as it runs. Although you can reduce energy costs by turning off your computer or having it go to sleep after a set period of time, some systems will take more energy to run than others.
