The processor is one of the most important components of a personal computer and its selection requires consideration of various parameters. Compatibility with the motherboard chipset and other components is a trivial matter, and there are many more important parameters for choosing the right processor for your application and budget. In this short and useful article, we will introduce various CPU parameters.
How To Buy The Right CPU For Your Laptop or PC Complete Guide
Intel or AMD
Among the two PC processor manufacturers, Intel and AMD have long been active, and users must choose between the two brands. At present, Intel and AMD produce and market new products every year, and despite all the restrictions, we are witnessing the arrival of the latest achievements of these two companies in the domestic market. However, in some cases, this happens with a long delay, and most importantly, choosing a much higher price compared to the dollar price causes users to deviate from their desires.
Architecture, lithography, and sockets
Each generation of Intel and AMD processors has three very general and main parameters, the most important of which is the microprocessor architecture. The CPU build architecture can specify other parameters such as lithography and socket. Intel is currently producing 10th generation Comet Lake processors based on the LGA 1200 socket and 14nm lithography. On the other hand, with the presence of third-generation RYZEN processors based on the AM4 socket and 7-nanometer lithography, AMD has disrupted all of the rival company’s calculations.
Due to many problems in recent years, Intel is still producing products based on the architecture and lithography of the past few generations, and according to new news, they can not have a CPU with newer lithography, at least until the end of 2020 or the beginning of 2021. To market. Finally, we must point out that based on the architecture and socket of your processor, you should choose the desired motherboard chipset.
Number of cores and processing threads
The most important parameter that is normally considered by users is the number of cores and processing threads. You can not determine the number of Cores and Threads with certainty and knowing the name of a CPU, and for this, you should refer to the manufacturer’s website. Both CPU manufacturers are now increasing the number of cores and strings, which is why new products have made significant progress in this regard. The number of processing cores leads to the separation of large processes and the processing threads also lead to the separation of smaller processes in order to complete operations faster.
In this way, the more cores and strings of processing, the higher the processing power of the CPU, but in the meantime, the operating frequency of the processor must also be considered. A CPU may have more cores and strings than another product, but due to its lower operating frequency, it has lower processing power. However, to choose the right CPU, you need to put different parameters together and weigh them all
Operating frequency
Each of the processing cores operates at a specific operating frequency and is measured in GHz (or MHz). The operating frequency of the processor depends on such things as the series of construction and application, although it is not possible to comment definitively on the factors influencing the frequency, as a comparison between two similar products, it is a determining parameter. Many of today’s processors have a lower base frequency and a higher speed boost frequency, and the latter leads to increased work speeds in cases such as the involvement of all cores and threads.
All processors operate at normal base frequencies and can only achieve higher frequencies if turbocharged technology is enabled or supported. In new Intel products, we see the use of a new technology called Thermal Velocity Boost, which determines the boost frequency of the processor based on the operating temperature. However, the difference between the normal boost frequency and TVB is not much different and the difference is around 200 MHz!
Cache
A CPU cache can store data that has already been processed and may be reused, and this data is stored at different levels of cache until the PC is turned off or restarted. There are generally three levels of cache in a CPU, with the lowest volume and highest speed being the first level of L1 Cache and the highest volume and lowest speed being the third level or L2 Cache. However, users pay more attention to the third level to choose a thinking brain, and L3 Cache has become a very important parameter.

Thermal design power or TDP
The maximum tolerable power in the CPU cooling system, called TDP, warns users what type of cooling to choose for their CPU. Manufacturing companies ready desktop computers, on the tub, mini PCs, and laptops based on the TPD CPU and GPU cooling choosing to act. The number given for TDP is a kind of average of thermal design power and it is possible to increase it in turbo boost mode. Thus, it is recommended that you use a cooler with a TDP above your CPU value on your PC.
Finally, in addition to the above, we can mention Hyper-Threading technology (process separation management in processing disciplines) and Virtualization technology (virtualization) as effective parameters.
