Few system components are as essential as the central processing unit (CPU). Most of what your computer actually does is processed by the CPU. This includes making game logic, running demanding apps, and doing tasks that seem simple. Therefore, if you are in the market for an upgrade, you must understand how to choose a better CPU.
The central processing unit (CPU) is sometimes referred to as the “brain” of the computer. It has the memory spots needed to take in data, analyze it, and then send something out. The CPU is always doing what it is told by computer programs, which are instructions for what data to process and how to handle it. A central processing unit is essential for every computer to function.
It is sometimes apparent what CPU is best for your needs. Data about processor “cores,” “threads,” “clocks,” and “cache” is readily available, but it takes some expertise to interpret it. Below, we will take you through our CPU buying guide with a thorough understanding of the basics, including how to select a CPU, what features to prioritize, and why they are essential.
How to Choose a Better CPU? 7 Simple Steps
Whether you are creating a new computer from scratch or upgrading an older one, picking out the most powerful central processing unit (CPU) is an extremely important step.
There are many different choices available to consumers when it comes to CPUs. You will find a rundown of the various kinds of CPUs that are available here. Below, we will go through 7 simple steps for finding a better CPU.
- What will you do with your computer?
First things first, you have to think about the specific purposes for which you will be utilizing your computer. The first step in purchasing your ideal CPU is to be sure of your intentions.
Suppose you want a new computer for essential internet use, email, and video streaming. In that case, you do not need as much processing power as someone who plans to play graphically intensive games or use their PC as a workstation.
Or, if you are a gamer who plays casual games like League of Legends, you can save money by purchasing a cheaper quad-core processor and putting that money toward other parts of your rig.
Look for a high-end processor with multiple cores and threads if you prefer to use your new computer for intensive tasks like video editing, graphics design, or playing the latest and greatest games. Also, the extra cores and threads will make graphics design, video editing, and other similar tasks run faster.
To summarize, the most important thing to figure out is how you intend to use the CPU.
- AMD or Intel: Which Should You Get?
Regarding central processing units (CPUs) for computers, AMD and Intel are the two most common options. Before 2017, Intel was your only valid option unless you were on a limited budget. But, today, you can have a great experience with either an AMD or an Intel CPU, so long as you choose the proper one for your needs.
Various CPU makers offer unique features and capabilities. Intel’s processors are known for having superior single-core performance and efficiency. As of this moment, this reflects higher gaming performance in general.
CPUs with multiple cores are the standard at AMD. Even though AMD chips’ single-core performance is not as good as Intel’s, the gap between the two is closing because of the increased number of cores on AMD chips.
AMD has made steady progress toward performance equal to Intel’s with its processor series like Ryzen and Threadripper. Also, AMD has surpassed Intel’s current products with Ryzen 5000 and chips like the Ryzen 5 5600X, which are usually better at both easy and challenging tasks that use multiple cores. Nonetheless, their new innovations have the potential to change their performance significantly.
All that said, Intel and AMD both make powerful gaming CPUs that can handle any of today’s games. To sum up, you can choose between the two companies based on a combination of factors, including pricing and performance.
- Cores and Threads
When choosing a central processing unit (CPU), you should think about the number of cores and threads.
Cores function similarly to separate CPUs but share a single chip. Since each core can only work on one thing simultaneously, more cores mean better multitasking. Nowadays, CPUs can have anything from 2 to 64 cores, with most having anywhere from 4 to 8. They can each handle their own responsibilities independently. Today, 4 cores (or 4 threads) are the minimum needed for most tasks.
Threads are the number of tasks that a CPU can perform at the same time. Many modern processors have simultaneous multithreading, which Intel CPUs call “hyperthreading.” This lets processors use the performance of cores that are not being used for other tasks.
Many modern CPUs have multithreading, which lets a single core create two separate threads when there are more threads available. This makes it easier to switch between tasks, and apps that use multiple threads, like video editors and transcoders, run much faster.
- Clock Speed and IPC
CPU clock speed and IPC are additional important factors for the PC.
How many groups of actions a processor can do in one second is measured in terms of its clock speed, which is measured in megahertz (MHz) or gigahertz (GHz). As a result, the higher the number, the faster it is. Most modern CPUs have a base clock speed (the slowest speed) and a turbo clock speed (the fastest speed). Their clock speeds change based on how much they are being used and how hot they are.
Also, CPUs have varying instruction per clock (IPC) values. Depending on the architecture, this is the number of jobs that can be done every second (one clock cycle). IPC depends significantly on how the CPU is designed, so newer chips (like a Ryzen 5 5600X with Zen 3 versus a Ryzen 7 2700X with Zen+) will perform better than older chips (like a Ryzen 5 5600X with Zen 3 versus a Ryzen 7 2700X with Zen+).
- Integrated graphics
Think of a central processing unit (CPU) that also has a graphics processing unit (GPU) built in. Integrated GPUs are sufficient for most processing activities because few people utilize graphics-intensive apps. This eliminates the need to buy and install an additional GPU. This saves time and money, as graphics cards can be expensive.
While most Intel processors (not including the 9900KF) include some integrated graphics solution, those with the letter “F” in the model number do not; even though they are not very strong, even an entry-level integrated graphics chip like the UHD 620 may manage 30 to 60 frames per second in older e-sports titles like CS: GO.
Although AMD’s desktop CPUs generally do not contain onboard graphics, the company offers several accelerated processing units (APUs) that include such functionality. They are more like the graphics from Intel’s 11th generation and work well enough for both beginner and e-sports games.
You should know that a higher number of graphics cores usually means better graphics performance. You will need to examine the evaluations of specific CPUs to see how capable they are because there are other aspects that affect gaming performance.
- Power and thermals
Power and thermal requirements are crucial factors to consider if you want a peaceful, efficient, or compact PC.
AMD and Intel need to offer more transparent information about how much power and heat their processors need. Instead, they use a rating called “Thermal Design Power (TDP)” to describe both. This is measured in watts, and it helps give you an estimated idea of how much power the CPU will need from the power supply and how powerful a cooler you will need to keep it running safely.
Low-power laptop CPUs can work with just a few watts, and the most powerful gaming systems use about 45 watts at most. But desktop CPUs can reach a maximum of 125 W in some situations, though most of the time, they use between 65 W and 95 W.
You can find out the same power and cooling needs of a processor by reading reviews, but if you want to build a quiet PC and are thinking about higher TDP CPUs that need about 100W, more giant and more efficient coolers are a good choice.
- Get the Right CPU Cooler
Last but not least, if you choose to go with a CPU that is able to overclock, you should consider upgrading to a more effective cooling solution. The term “overclocking” refers to the practice of operating a computer’s central processing unit at speed greater than its default. To make it go faster, more energy must be supplied to it. However, the greater the input power, the hotter it will become.
Processors can only work at a specific temperature for a certain amount of time before they have to slow down. On the other hand, if you can keep your CPU’s temperature within a reasonable range by matching the increase in temperature that happens when you overclock the processor with a better cooling solution, you will be successful.
The more efficient your cooling system is, the more you can overclock your processor (to an extent). Conventional central processing unit (CPU) coolers are typically included with CPUs. As a rule, the stock cooler needs to be revised to severe overclocking. (Although the stock coolers on AMD’s new Ryzen processors are rather good.)
