Every computer needs a processor to make it work, just like a human brain needs to work, whatever the computer is big or small. Processes the user's input with the appropriate program or application, publishes the results to the user, and processes everything until it is stored on a storage device. Ordinary desktop computers or laptops are capable of displaying results by completing any instruction in 1 million parts of 1 second, which supercomputers can do in 1 billion parts of 1 second.
In Bangladesh, there are two popular companies for computer processor - Intel and AMD. Though AMD has some running series, Intel is more popular.
Intel core i3 processor is ideal for browsing Internet, watching movies, and other common task for daily use.
Intel i5 processor perfects for a little bit gaming, photo editing, browsing and so on.
Intel Core i7 processor is more advanced and ideal for high-end gaming, audio-video editing, programming and applications that require powerful processing.
Core i9 processor is a new series and almost same as Core i7 but has faster processing power, more cores, and more cache.
AMD is a high-performance processor for gaming, streaming and VR with clever machine intelligence and advanced processing.
Processor clock frequency
The processing power of a processor depends on its clock frequency. The processor is like a door called a clock. Clock frequency is the amount of clock speed of a processor through which all the signals of 0 and 1 come and go. The door of this clock will open and close as many times as 0 and 1 will come and go. The faster the door opens and closes, the faster the instruction process.
The processing power of a processor is calculated as a fraction of a millionth of a second. Simply put, 1 GHz of a processor means it takes 1 billionths of a second to complete a calculation. In other words, the clock gate of the processor is opened and closed 1 billion times in 1 second.
Nowadays, in order to increase the performance of modern computer processors, multiple processors are placed in the CPU chip in the processor so that the instruction execution capacity of the computer is increased and the execution time is also reduced. Quick results can be published in a very short time. Which is allows all processor cores in a CPU chip to work simultaneously.
Processor cache memory
Processor cache memory is an important factor associated with processor performance. When the CPU is working with the same type of data over and over again, it temporarily stores that data in its cache memory to facilitate the work.
