The CPU on a computer motherboard mainly has the following functions

1、Process instructions and data

The CPU is the core of a computer, responsible for executing program instructions and processing data operations

2、control computer operations

Coordinate and manage the operation of other hardware components (such as memory, hard disk, graphics card, etc.)

3、Arithmetic and Logic operations

Perform mathematical calculations (addition, subtraction, multiplication, division) and logical judgments (and, or not, etc.)

4、Cache Management

Improve the data access speed through multi-level caching (L1/L2/L3 Cache)

5、Multi-Core/Multi-Threadin processing

Modern cpus support multi-core and hyper-threading, enhancing parallel computing capabilities

6、Power and Thermal Management

Dynamically adjust voltage and frequency (such as INTEL's SpeedShift.AMD cool'n Quiet) to optimize energy efficiency and heat dissipation

7、Bus and interface control

Communicate with the motherboard chipset via the Front Side Bus (FSB), QPI or Infinity Fabric(AMD)

8、Virtualization support

Hardware-level virtualization technologies (such as intel VT-X、AMD-V) enhance the performance of virtual machines

9、security Features

Provide hardware Encryption (such as INTEL AES-N、AMD Secure Memory Encryption) and trusted execution environments (such as TPM)

10、Integrated graphics card support (for some cpus)

 Such as Intel HD Graphics card AMD Radeon vega,The output can be displayed without a dedicated graphics card
