There are often novices who confuse servers and ordinary computers. In fact, the difference between them is not the appearance. Let’s make a simple analogy. A PC is equivalent to an outpatient doctor who knows everything, but the doctor’s technology is not superb, and the server is a certain aspect. expert.
Of course, we must first make a point: The CPU of a server and an ordinary PC are not universal. The instructions of the server CPU are generally RISC (reduced instruction set). According to research, in most applications, the CPU only uses a few commands, so the researchers designed the instruction set based on this situation, and used centralized command combinations to achieve various requirements. The advantage of this design is that it is more targeted, can be specifically optimized according to different needs, and has higher processing efficiency. The corresponding is CISC (Complex Instruction Set). Its characteristic is to integrate various commonly used functions into one as much as possible. For example, the MMX, SSE, SSE+, 3D!NOW! and so on that, we often hear are all of this type. of.
In addition, the main differences are the following:
The server CPU is designed to run continuously for a long time, and is basically designed to work continuously all year round, while the ordinary desktop CPU is designed for 72 hours of continuous work.
The CPU design of a server generally has to consider its multi-channel function, that is, multiple CPUs work together, while a PC generally has only one CPU.
The cache also determines the performance of the CPU. Because the server CPU has high requirements for computing performance, the server CPU often applies the most advanced technology and technology and is equipped with one, two, and three levels of cache, which makes it more powerful. L3 cache has only recently appeared in ordinary desktop CPUs
Server CPU and ordinary CPU interfaces are often different. At present, most of the server CPU interfaces are Socket 771, Socket 775, LGA 2011, and LGA 1150. Compared with ordinary CPU interfaces, although many of them are the same, the motherboards actually matched are different. The motherboards equipped with server CPUs usually do not have graphics card slots, because the core graphics cards that come with the CPU can meet the demand, and the CPU bus bandwidth is higher than that of home CPUs.
The server CPU exists for long-term stable work, and is basically designed to work continuously throughout the year. Server CPUs are very different in terms of stability and reliability compared to home CPUs. Generally, servers are turned on and run 365 days a year, and only occasionally shut down for maintenance, which requires extremely high stability.
The above is the analysis of the difference between server CPU and ordinary CPU.

In addition, the main differences are the following:
1. Running time
The server CPU is designed to run continuously for a long time, and is basically designed to work continuously all year round, while the ordinary desktop CPU is designed for 72 hours of continuous work.
2. Multi-channel interconnection
The CPU design of a server generally has to consider its multi-channel function, that is, multiple CPUs work together, while a PC generally has only one CPU.
3. Different caches
