Buying a processor (CPU)
Today’s computers are made of many parts, the most important of which is the CPU. The word CPU stands for the central processing unit. This part is the brain of the computer and is responsible for performing complex calculations that make all the requested processes done correctly. The main building of a processor is made by placing millions of micro-transistors on a chip. The general operation of this device is based on the disconnection and connection of the electric current by micro transistors, which are coded as 1 and 0. The processing process is a complex set of these codes. The main chip and a few other parts form a package that is under a metal cover. This part is placed in its special socket on the motherboard and is connected to it through special pins. A heatsink is usually placed on top of it to prevent heat damage to the internal structure.
These parts have different types. Some are designed to perform a specific type of processing that is used in scientific projects. Others are built for servers, have high computing power, and have special security features that are essential for business use. The most widely used type of CPU is made for home use, which has features that make it suitable for everyday use by normal and professional users. Laptop and desktop CPU types are the same in terms of structure; But their energy consumption is different. The conventional method for classifying these devices is the number of cores and their structure, which will be discussed further.
This model has a processing core that is responsible for doing everything. These products are not very optimal, they do not have much processing power and are mostly seen in various models of old computers .
The need for more processing power increased the number of processing cores. Dividing the work between the cores makes the calculation faster. Almost all modern computers use multi-core processors. The number of cores depends on the category of energy consumption and its processing power, for example, low-consumption examples usually have 2 cores. As the power increases, the number of cores also increases.
Main CPU manufacturers
Intel has been working in this field since 1968. This company is ahead of its competitors in the field of manufacturing these parts and has a larger share of the market. The types of CPUs are Intel, Pentium, Celeron, Core i, etc., whose names are familiar to many people. Celeron, Pentium and Core i3 are economical and cheap series of this product. Core i5 is in the middle category. Core i7 and Core i9 are the most powerful for normal use. Xeon series are also made for commercial use, servers and workstations.
This American company, founded in 1969, is Intel’s biggest competitor. Although Intel has been more successful in selling its products, AMD is by no means a loser in this competition; Because the main competition is in the field of manufacturing technology. In recent years, these two companies have repeatedly exchanged the position of “the most advanced CPU manufacturer”. AMD Rysen series CPU was recently introduced and has gained many fans. Rysen 3 low power and economical; Rysen 5 medium class; Rysen 7 and Rysen 9 are strong and expensive series. Also, Ryzen Threadripper with 64 cores is one of the most powerful processors on the market.
What points should we pay attention to when buying a CPU?
The real cores are the calculation units, and the more they are, the more powerful the processor will be. Virtual cores perform pre-processing operations and are actually part of real cores. The frequency of each core indicates the calculation rate per second. Another important technical characteristic of processors is their cache value. Cache is a memory that is used to reduce RAM access time. It is smaller, faster, and more expensive than RAM. Using a cache reduces data access latency; As a result, the more cache you have, the faster your processor will be.
Year of manufacture and generation
Newer generations use up-to-date technologies and are more powerful. According to Moore’s law, the number of transistors on a fixed-area chip roughly doubles every 2 years. For example, a 9th generation Core i3 CPU may be more powerful than a Core i5 a few generations ago.
Each CPU manufacturer has its own motherboard socket. This port may be different in different generations of a particular series. If you are going to buy a CPU but don’t want to change the motherboard, you should pay attention that the sockets match.
Processor usage and price
Technical specifications and processing power determine the CPU price. The price of a powerful CPU is expensive; So make sure you need it so you don’t overspend. Buying a cheap and economical dual-core CPU is recommended for normal home use. The price of a quad-core CPU varies depending on its generation and series. These products are stronger and suitable for heavier uses. The price of mid-range CPUs (such as Rysen 5 and Core i5) is lower and its power is enough to run games. Computer games require a powerful graphics card. If your budget is limited, we suggest spending it on buying a more powerful graphics card. To see the price of the CPU i5, the price of a second-hand CPU, the price of the CPU core i7, and the price of the CPU core i5, you can visit the products available in Isam. Buying a second-hand CPU is one of the best ways to get this product economically.
Higher power means higher energy consumption and more heat generation. To use the full power of the processor, you must control its temperature with a CPU fan; Otherwise, parts may be damaged.
Frequently asked questions
What is clock speed?
The clock speed indicates the speed of the chip and in fact the number of cycles that the CPU performs in each second. In general, the higher the clock speed number, the higher the speed of your desired product. Most of today’s CPU models on the market are designed in such a way that they can adjust their clock speed based on the temperature of the part and the number of tasks it performs.
What is the CPU core?
Cores are the parts that are placed inside the processor. Today’s CPUs have between 2 and 32 cores, each of which performs its own tasks. In general, most CPUs in the market have 4 to 8 cores, and you can choose the most suitable option according to your peripheral needs.
What is Thread?
A thread refers to the number of independent processes that each chip can perform in one second. If your processor has multithreading capability, it can divide each core into two threads. More thread value means higher multitasking and more performance for the user. If you intend to edit professional videos, this feature will be very useful for you.
