For servers, the motherboard becomes the carrier of its high performance. For server motherboards, the chipset can be called the soul of the motherboard; if the chipset cannot work well with the CPU, it will seriously affect the computer. The overall performance cannot even work properly, and the chipset requires good compatibility, interchangeability and scalability.

For servers, the motherboard becomes the carrier of its high performance. For server motherboards, many people call the chipset the soul of the motherboard, which is most appropriate. If the chipset cannot work well with the CPU, it will seriously affect the overall performance of the computer or even fail to work properly. The chipset requires good compatibility, interchangeability and scalability, and also has the highest requirements for stability and comprehensive performance.
What is a server CPU?
Currently, server CPUs are still distinguished according to the CPU instruction system. They are usually divided into two categories: CISC type CPU and RISC type CPU. Later, they were divided into CISC type CPU and RISC type CPU. A 64-bit VLIM (Very Long Instruction Word Very Long Instruction Set Architecture) instruction system CPU has emerged.
1. CISC type CPU
CISC is the abbreviation of "Complex Instruction Set Computer" in English. The Chinese meaning is "Complex Instruction Set", which refers to the CPU produced by Intel. The x86 (a naming convention for Intel CPUs) series CPUs and their compatible CPUs (CPUs produced by other manufacturers such as AMD, VIA, etc.) are based on the PC (personal computer) architecture. This kind of CPU generally has a 32-bit structure, so we also call it IA-32 CPU. (IA: Intel Architecture, Intel architecture). CISC CPUs currently mainly include Intel server CPUs and AMD server CPUs.
2. RISC CPU
RISC is the abbreviation of "Reduced Instruction Set Computing" in English, and the Chinese meaning is "reduced instruction set". It was developed on the basis of the CISC (Complex Instruction Set Computer) instruction system. Someone tested the CISC machine and showed that the frequency of use of various instructions is quite different. The most commonly used are some relatively simple instructions, which only account for 20% of the total number of instructions, but the frequency of occurrence in the program accounts for 80%. A complex instruction system will inevitably increase the complexity of the microprocessor, making the development of the processor long and costly. And complex instructions require complex operations, which will inevitably reduce the speed of the computer.
