This article is to share with you about how much CPU usage is normal. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

CPU usage is normal as long as it is not always above [50%], and it is normal for CPU usage to be less than [15%] without running other programs.

CPU usage is actually the CPU resources consumed by the program you are running, indicating how the machine is running the program at a certain point in time.

CPU usage is normal as long as it is not always above 50%. It is normal for CPU usage to be less than 15% without running other programs.

CPU determines its execution behavior according to the instructions extracted from the memory. In the decoding phase, the instruction is disassembled into meaningful fragments. Interprets numeric values into instructions according to the instruction set architecture definition of CPU.

Part of the instruction value is an arithmetic code, which indicates which operations to be performed. Other values usually provide the necessary information for the instruction, such as the target of an addition operation.

This is normal if your cpu occupancy varies between 0% and 75%. But if it is often above 90%, or even 99.9% or 100%, the reasons are as follows:

1. Anti-virus software causes failure due to the new version of KV, Jinshan and rising have joined the random monitoring of web pages, plug-ins and emails, which undoubtedly increases the burden of the system.

2. The driver is not certified, resulting in a large number of beta drivers that take up 100% of CPU resources, resulting in a failure that is difficult to find.

3. Viruses and Trojans cause a large number of worms to replicate rapidly in the system, resulting in a high rate of CPU resources.

Extended data:

What does cpu dominant frequency mean?

The cpu main frequency is the clock rate (CPU Clock Speed) at which the cpu kernel works. The so-and-so cpu is commonly referred to as the number of megahertz, and this number of megahertz is the "main frequency of cpu". Many people think that the main frequency of cpu is its running speed, but it is not.

The main frequency of cpu represents the oscillation speed of digital pulse signal in cpu, which is not directly related to the actual computing power of cpu. There is a certain relationship between the main frequency and the actual operation speed.

But at present, there is no definite formula that can quantify the numerical relationship between the two. Because the computing speed of cpu also depends on the performance indicators of all aspects of the cpu pipeline.

Because the cpu main frequency does not directly represent the operation speed, under certain circumstances, the actual operation speed of cpu with higher main frequency is likely to be lower.

For example, most of AMD's AthlonXP series CPU can reach Intel's Pentium with a lower main frequency.

The 4-series cpu has higher CPU performance of the main frequency, so the AthlonXP series cpu is named after the PR value.

Therefore, the dominant frequency is only one aspect of the performance of cpu, and does not represent the overall performance of cpu.
