What is CPU? CPU manufacturers are commonly used today

The concept of CPU is no longer strange to laptop users. However, many people still do not know what a CPU is. Let’s join lassho.edu.vn to immediately refer to the following article What is CPU and the most commonly used CPU manufacturers today!

What is CPU?

CPU stands for Central Processing Unit , also known as central processing unit. The CPU helps to store all information and carefully calculate all operations, data and give commands to control the operation of the laptop.

CPU function

The CPU has the main function in processing all the computer programs of the laptop. In addition, the CPU also processes input data and all instructions are transferred to the CPU through software or hardware running on the laptop.

Structure of CPU

Control Unit (CU – Control Unit)

At the control block, requests and operations from the user will be compiled into machine language. Then every control process will be handled correctly. This is considered an important part of the processor when it is composed of logic circuits.

Arithmetic Logic Unit (ALU)

The ALU calculation block holds the function of calculating mathematical and logical numbers carefully and accurately. After that, the results will be given and passed to the next processing processes.

Registers (Registers)

Registers with high access speed have the function of temporarily storing results, memory locations, operands, etc. There are many different types of registers, of which the most important is the set of registers. count the program with the task of specifying the instruction to be executed in the next steps.

Opcode

Opcode is a detail that holds the main task of recording the CPU’s machine code so that the instructions in the executable file are executed.

Control part

This is the important part that controls the clock frequency and blocks. In particular, the clock has the effect of synchronizing operations inside and outside the CPU. The interval between each clock is called the clock cycle with the clock speed in million units per second (MHz).

The CPU’s structure includes main parts such as: control block, ALU calculation block, …

How fast is CPU processing speed?

The CPU’s processing speed is its computing and working frequency measured in GHz or MHz. If the same chip line as Core i3, higher clock means faster processing speed, better working ability.

However, if between two different chip lines such as Core i3 dual core 2.2GHz and Intel Pentium Dual core 2.3GHz, it is not possible to compare immediately. The reason is because the processing speed of a laptop depends a lot on cache memory, RAM, graphics chip, hard drive, etc.

Types of CPUs being used today

Intel’s CPU

Intel currently has popular CPU types such as: Intel Core i3, i5, i7, i9 and Intel Xeon. Intel has improved a series of features as well as cut old technologies to optimize processing speed, data transmission … for the CPU as well as reduce power consumption.

AMD CPUs

AMD is one of the largest chip and CPU brands in the world. Some popular AMD CPUs are used by many people such as: AMD Ryzen 5, AMD Ryzen 7 and AMD Ryzen threadripper. AMD CPUs stand out with much better overclocking on laptop devices.
