Processor Buying Guide 2022

The processor is crucial when creating or updating a PC. We’ll assist you in making the best decision for your needs. Intel Xeon SRFPP and AMD 100-000000054 EPYC 7502 might seem like a good option, but what things should you consider before buying a new processor?

What is a Processor, or CPU?

A circuit board within a computer known as a processor, or CPU, carries out instructions on behalf of programs. Millions of instructions can be processed in a second by modern computer processors. The primary chip in a computer is the processor.

It’s challenging to assess new technology without taking the processor into account. Even for techies, it might be challenging to understand what a processor does.

The brains behind a computer are its processors. They manage the logic that your computer uses to run applications and conduct calculations. 

Terms You Should Know 

Clock Speed

The clock speed of the computer processor is quantified in gigahertz (GHz). It provides the number of activities that a processor can complete in a second. The higher the computer processor clock speed, the greater the operation number. Your computer or laptop will operate quickly when launching programs, downloading files, and exporting images when the clock speed is high. 

You’ll see a minimum clock speed and a turbo clock speed when buying a processor since most current CPUs alter their clock speeds depending on the their temperature and programs. 

Core Count 

Any laptop or desktop CPU will typically have two or four cores. It has dual- and quad-core names. Some modern models come with six or even eight cores. Better computers and laptops have more cores. The rationale behind this is that having more cores enables your computer to perform numerous activities simultaneously without experiencing any lag. Therefore, additional cores will be ideal for you if your requirement comprises running numerous programs or opening numerous web browser tabs.

Nowadays, you’ll often need at least four cores or at least four threads.


It describes how many separate processes a processor can manage simultaneously. In other words, having more threads leads to better performance and multitasking abilities. These are the biggest numbers of processes that chips can manage simultaneously, which corresponds to the no. of cores in theory. Although many CPUs support multithreading, one core can create two threads, thanks to this feature. This is known as Hyper-Threading by Intel, and AMD says it Simultaneous Multithreading (SMT). More threads result in greater multitasking and improved performance on multi-threaded software like transcoders and video editors. 

Thermal Design Profile (TDP) 

The heat that a chip can (or should) produce at stock speeds is known as the Thermal Design Profile/Power (TDP), and it is expressed in watts. You can ensure that your CPU cooler can manage the dissipated heat that your power supply unit can supply enough power by knowing, for instance, that the Intel Core i7-8700K has a 95 watts TDP. But keep in mind that overclocked CPUs generate substantially more heat. Knowing your TDP will help you choose the appropriate cooling and power supplies to support your computer processor. Additionally, other factors, such as process node size and overall architecture efficiency, also affect performance, a higher TDP typically corresponds with faster performance.  


The onboard cache of a processor is employed to expedite access to information and instructions between your processor and random access memory. There are 3 different cache types: L1, is the fastest but the smallest; L2, the larger but slower; and L3, the larger but slower. The RAM is substantially slower than a processor’s on-chip cache when a processor wants data that isn’t present in any of these locations and isn’t present there either.

The cache size shouldn’t be given much consideration because it’s difficult to translate to real performance and more crucial considerations to take into account. 

Instructions Per Clock Cycle (IPC) 

Though two CPUs are from different firms or created on different designs from the same IT shops, even if they have the similar clock speed and no. of threads, they will produce different levels of IPC. The architecture of the CPU has a significant impact on IPC, so newer chips (such as a Ryzen 5 5600X with Zen 3 versus a Ryzen 7 2700X with Zen+) will perform better than older ones. IPC is often determined through benchmark testing and is not typically mentioned as a specification.

Processor Applications 

Everyday Computing 

An entry-level chip with two or four cores can be exactly what you need if all you want is a chip that will let you stream video, surf the web, and perform basic productivity chores like word processing and light spreadsheet work. But it might be best to move up a model or two if you frequently find yourself performing more than one of those simple chores at once. 

High-end Gaming 

Choose a midrange Intel Core i5 or AMD Ryzen 5 CPU with high clock rates if your primary concern is high-end gaming performance. Although you can buy any regular processor, it is unwise to invest in a processor only for gaming purposes because the graphics card is more crucial for gaming than the processor. 

Clock Speed, Cores, or Thread: What Should You Increase? 

The simple answer to this question depends upon the kind of activities you are going to perform. Faster responsiveness and program load times are correlated with higher clock speeds (though RAM and storage speed are key here as well). Single-threaded tasks (like audio editing and some older apps) can also be completed more quickly because of higher clock speeds. Many well-known games are still only minimally threaded.

But a lot of contemporary programs can benefit from having numerous cores and threads. Prioritise the number of cores if you multitask frequently, edit high-resolution films, or perform other difficult, time-consuming CPU-intensive jobs. However, a clock speed of between 3 and 4 GHz with four and eight cores is sufficient for the great majority of players  

and basic computer users. 

Final Words 

When selecting a CPU, think about what you’ll use it for first, then calculate your budget for it once you know how much you’ll be spending on other parts. For more information, see our guides to the best SSDs, RAM, graphics cards, and power supplies. While CPUs are vital, it makes little sense to mix a fast chip with mediocre graphics (unless you don’t play games) or a mechanical hard drive that spins slowly. Now you can easily pick between AMD 100-000000054 EPYC 7502 and Intel Xeon SRFPP.
