Ask a question about CPU frequency, please point it with a high finger

The current Intel Core i3 does not have turbo boost technology, so it is impossible to exceed the default frequency, and your situation is actually normal, because the i3 processor will automatically downspeed when working at low load, and if you play a large game, the main frequency will rise.

How do you check the current frequency?,Is it measured by software?,Many of the measurements are not very accurate.,Some errors.,If you suspect that the frequency is inconsistent with what the merchant promised at the time, you can go into the BIOS to look at your CPU frequency.。

There will be a difference in how much, just like some storage devices such as hard disks and USB flash drives, it is impossible for 2G capacity to be just 2G capacity, the same reason. If you want to overclock, you can go to the Bois settings, you should ask for details!

Because it is automatically inverted in Hoi An's actual workload, you try to open a little more software, or use the oven software, and then look at the CPU, it will definitely be different. Of course, the highest frequency will not be higher than the default frequency.

The current design is such that it automatically reduces the frequency during low-load work. You can do multithreading or something and see (working at full capacity) and the frequency should come up.

This is a normal friend, and if it exceeds the default, it is called overclocking. Do not worry.

Is it that it turns on the function of automatic energy saving, when your usage rate is not high, the current CPU will automatically reduce the frequency to achieve the purpose of energy saving.

Because the i3 CPU is smart, it will be a little less frequent when you process very little data, which is used to save energy.

Because you don't have a lot of programs that use the CPU, it doesn't take up much CPU resources.

The computer runs fewer programs, so there is no overclocking. Your computer configuration is pretty good, and if you play normally, you won't be overclocked.

Intel's new model CPU will run at reduced frequency when the task is not busy! It's okay.

If you don't overclock, the current frequency will definitely be lower than the default frequency.

Exceeding the default frequency is called overclocking, which is not good for the computer.

Normal. Look at the current frequency of use.

CPU frequency is the clock frequency of the CPU, which is simply the abbreviation of the operating frequency (the number of synchronization pulses that occur in 1 second) during CPU operation. The unit is Hz. It determines the running speed of the computer, and with the development of the computer, the main frequency has developed from the past MHz to the current GHz (1G=1024M).

Generally speaking, in the same series of microprocessors, the higher the frequency, the faster the computer, but for different types of processors, it can only be used as a reference.

In addition, the computing speed of the CPU also depends on the performance indicators of all aspects of the CPU pipeline. Since the main frequency does not directly represent the computing speed, in some cases, it is likely that the actual computing speed of the CPU with a higher frequency will be lower. Therefore, the clock speed is only one aspect of CPU performance, and does not represent the overall performance of the CPU.

When it comes to the processor frequency, it is necessary to mention two concepts closely related to it: frequency doubling and external frequency, the external frequency is the base frequency of the CPU, and the unit is also MHz. The external frequency is the speed of synchronous operation between the CPU and the motherboard, and the external frequency of most of the current computer systems is also the speed of synchronous operation between the memory and the motherboard.

The frequency doubling is the multiple of the ratio of the main frequency to the external frequency. The main frequency, external frequency, and frequency doubling, and their relationship formula: main frequency = external frequency doubling.

In the early days, CPUs didn't have the concept of frequency doubling, when the main frequency and the speed of the system bus were the same. With the development of technology, the CPU speed is getting faster and faster, and accessories such as memory and hard disks can gradually not keep up with the speed of the CPU, and the emergence of frequency doubling solves this problem, which can make the memory and other components still work at a relatively low system bus frequency, and the main frequency of the CPU can be infinitely increased by frequency doubling (theoretically).

People can regard the external frequency as a production line in the machine, and the frequency doubling is the number of production lines, and the speed of a machine's production speed (main frequency) is naturally the speed of the production line (external frequency) multiplied by the number of production lines (frequency doubling). Nowadays, manufacturers have basically locked the frequency doubling, and the only way to overclock is to start with the external frequency, and use the combination of frequency doubling and external frequency to jumper the motherboard or set soft overclocking in the BIOS, so as to achieve a partial improvement in the overall performance of the computer. So when buying, try to pay attention to the external frequency of the CPU.

The actual operating frequency of the CPU is the product of the outer frequency and the octave, the outer frequency is like the width of the road, and the octave is like the number of vehicles allowed to pass per unit time on the road. At present, the external frequency of mainstream CPUs is usually 133 or 133, for example, Pentium III 667 is 133 external frequency multiplied by 5 times. Generally speaking, CPU performance with high external frequency is better, which is why the PI667 with 133 external frequency will be on par with the PIi700 with 100 external frequency.

Therefore, when choosing a CPU, in addition to looking at the total frequency, you should also pay attention to the composition of the frequency. ;

CPU usage is related to CPU performance, generally speaking, the lower the CPU usage for the same application, the higher the CPU performance. There is a certain relationship, but it is not necessarily a proportional relationship. It is also related to the temperature, graphics card memory and other supporting equipment.

A CPU with high performance but less memory may also take up more.

CPU usage refers to the load of the CPU. Open the explorer (ctrl+alt+del), you can see the CPU usage, which is expressed as a percentage (%), generally between 5% and 100%, and the value depends on the load of the CPU. A higher percentage value indicates a higher load on the CPU, and vice versa.

So the relationship between CPU frequency and usage rate comes out. When processing the same amount of data, the CPU with the highest frequency has a low utilization rate. The CPU with a low clock speed has a high usage rate.

CPU usage refers to the percentage of CPU used by a program in real time during running, which is a statistic of CPU usage over a period of time. This indicator shows how much CPU is occupied during a certain period of time.

The CPU (Central Processing Unit) is the computing and control core of the computer system, and is the final execution unit of information processing and program operation, which is equivalent to the "brain" of the system. When the CPU is too busy, just like the "human brain" processing too many things concurrently, it will reduce the efficiency of doing things, and even lead to crashes and "downtime" in severe cases. Therefore, understanding how CPUs work and properly controlling the load is an important means to ensure the stable and continuous operation of the system.

CPU performance first of all has a lot to do with the architecture, no matter how high the frequency is, how strong the number of cores, if the architecture itself is inefficient, then the performance of the CPU will not be good.

High CPU usage can slow down your computer, but it's normal if it happens once in a while and recovers quickly. But if it stays high for a long time, there will be a problem, and many people will think of poisoning at the first time. By upgrading the anti-virus software and eliminating the virus, after ruling out the cause of the virus, if the CPU resource occupancy rate is still high, many people don't know what to do The first time they think of the virus, this is normal, after all, this is also a typical symptom after being infected with the virus, but it does not mean that there must be a virus. If the cause of the virus is ruled out, I suggest starting with the process, checking which process is occupying a lot of CPU resources in the task manager, remembering the name of the process, and searching for other people's descriptions of the process on the Internet, so that you can use the successful experience of others to analyze and deal with the faults you encounter. It is important to note that some system processes can also be exploited by viruses.

The higher the frequency of the same CPU, the faster.

However, the same CPU frequency increase is less than 1GIt's hard to feel the difference subjectively.

Because the gap is only a few seconds.

If you use heavy applications, the CPU should be overclocked. To put it simply, a small road can walk two people side by side, and now that you are overclocked, the wide road is equivalent to overclocking, and at this time you can walk three people. Isn't it equivalent to having more tasks to deal with at the same time, when the efficiency is high, the faster.

However, too much overclocking will cause a series of problems, such as increased heating, increased power consumption, and affected lifespan. If your core is 1 (old machine) overclocking the boost is noticeable. The two cores are also obvious.

Dual-core and four-threaded words can also be felt. If the physical core is greater than or equal to four, it will not be noticeable (except for software that only supports a single thread). Overclocking is good for gaming, video and audio transcoding, and tasks that require high single-threaded or multi-threaded usage.

Hope it works for you.
