How to find out a multi-core processor or not. Three ways to find out how many nuclear processor stands in PC. Programs to determine the number of processor cores
Instruction
If you have installed operating system Windows, learn how many nuclei in your processor can be through properties. To do this, select the Computer icon on the desktop, click Alt + Enter or right button Mice and in the context menu "Properties".
A window will open with information about the operating system, processor, random access memory and computer name. On the right there will be references, among which you need to find "Device Manager".
The dispatcher will indicate the equipment that you have installed. Find the Processor item in the list and click on the arrow next to it. A column unfolds, in which the number of your processors will be indicated.
You can run the task manager using Ctrl + Shift + ESC combination. Open the tab called "Speed". The number of windows in the section "TsP loading chronology" corresponds to the number of cores of your processor.
If the computer is enabled on the computer, the imitation of the multi-core processor is included, then the task manager will show the number of symulated cores. This can be defined if all the kernels show a completely identical load. Then you can come in handy free utility CPU-Z. The CPU tab shows all information about the processor. Below is the Core window where the number of cores is indicated.
You can use another free PC Wizard program. It can be downloaded from the developer's website. Install the program to the computer. Run the PC Wizard.exe file, click the "Iron" tab, then the "processor". Find the "Element" section on the right, and in it the Number of Core. The "Description" section shows the number of cores.
There is an opinion according to which the power of the computer is primarily measured by the number of cores in the processor. Allegedly multi-core processors, which contain two or more nuclei in one case, are considered the most productive, which, accordingly, has a positive effect on the speed of the computer as a whole. This is partly true if you do not forget that other components are responsible for the speed of work PC.
In multi-core processors, the clock frequency is usually reduced, and this is done intentionally - to reduce the power consumption of the processor without affecting its performance. On some models, the clock frequency of each nucleus may vary depending on its individual load. But how much the performance of the application will increase, it's hard to say. The fact is that using both single-core and lot nuclear processoryou can not see the difference in the application itself if it is not optimized - it simply will not receive any benefit from additional cores. Moreover, in some cases such applications begin to work slower! Fortunately, there are few such applications and most of them was created before the appearance.
In general, to rely only on the number of cores, speaking about the power of the computer as a whole, it would not be quite right. And yet the number of nuclei is indeed one of the important indicators, so if you do not know how to see their number, I will help you.
There are enough options to find out this information. I'll show the most simple waysthat do not require temporary costs and resources.
Task Manager
The easiest way to use. For example, on Windows 7, this method works great.
You need to run the task manager. I already told in detail how it can be done. One of the most simple methods - CTRL + SHIFT + ESC key combination, or hover the mouse over the tray (taskbar in Windows), click on the right mouse button and select "Run Taskbang".
The task manager window opens. Open the "Speed" tab. There is a so-called "CPU loading chronology" - calculate the number of windows that means the number of cores. If two windows are two, then you have a dual-core processor if four are quad-core, etc.
In my opinion, this is one of the most successful ways, the use of which will take no more than a minute of your time.
Device Manager
Another method that allows not to resort to the use of additional software, it is a built-in Windows utility called "Device Manager".
Let me remind you that you will easily open the device manager so: Move the mouse over the computer icon on the desktop (if any, find it in the menu by clicking the "Start" button, click on the right button and select "Properties".
A window will open with the characteristics of the basic information about your computer. In his left part, you can see the "Device Manager" item - click on it.
Before you - Device Manager window. Find the Processor item and click on it. Calculate how many processors you see in the list - this is exactly the number of nuclei has your processor.
Unfortunately, the specified method has one important minus. On some processors that support Hyper-Threading (hyperpotoration), each kernel can share data processing into two independent streams. And this means that if your processor has four cores in reality, then you will see eight at once, using the specified method. If your processor uses this technology, use the task manager in this case is not worth it, since you get distorting reality information.
Sophisticated software
Of course, it is possible to see the number of cores using various programs and applications. Today I will not resort to the favorite all Everest program, but will tell about CPU-Z.
CPU-Z is a small utility that allows you to find out all the necessary information about the computer. For example, it shows all installed components, the temperature of some components and, of course, the number of cores in the processor.
Download CPU-Z from the official site and install it on your computer. There is, by the way, the portable version that does not require installation on the PC.
Run the program and directly on the CPU main tab, please note the Cores item, which is located at the bottom of the window. It is here that the number of nuclei in the processor is indicated.
You can ask your questions with the help of comments.
In our progressive time, the number of nuclei plays a dominant role in choosing a computer. After all, it is due to the kernels located in the processor, the power of the computer is measured, its speed during data processing and issuing the result obtained. There are kernels in the processor crystal, and their number in this moment Can reach from one to four.
At that time "no longer time, when there were no four-core processors, and the two-cores were in the wonder, the speed of the computer's power was measured in the clock frequency. The processor processed only one stream of information, and as you understand, while the resulting processing result reached the user, took an inval amount of time. Now the multi-core processor, using specially designed improved programs, shares data processing into several separate, independent flows from each other, which significantly speeds up the resulting result and increases the powerful data of the computer. But it is important to know that if the application is not configured to work with multi-core, then the speed will be even lower than that of a single-core processor with a good clock frequency. So how how many nuclei in the computer?
The central processor is one of the most important parts of any computer, and determine how many nuclei in it is quite a satisfying task for a beginner computer genius, because your successful transformation into an experienced computer bison depends on it. So, define how many nuclei in your computer.
Reception number 1
- To do this, click computer mouse On the right side, clumsy on the computer icon, or the context menu, located on the desktop, on the computer icon. Select the item "Properties".
- A window opens from the left, find the "Device Manager" item.
- In order to reveal a list of processors located in your computer, click on the arrow placed the left of the main points, including the Processors item.
- Calculating how many processors are in the list, you can say with confidence how many nuclei in the processor, because each kernel will have even a repeating, but separate entry. In the sample presented to you, it can be seen that the cores are two.
This method is suitable for Windows operating systems, but on intel processorsHypertension (Hyper-Threading Technology), this method is likely to issue an erroneous designation, because in them one physical core can be divided into two streams independent one from one. As a result, a program that is good for one operating system for this, every independent flow for a separate nucleus will consider, and you will result in an eight-core processor. Therefore, if your processor supports Hyper-Threading technology, consult a special utility - diagnostics.
Reception number 2.
There are free programs for curious about the number of nuclei in the processor. So, the unpaid CPU-Z program, quite cope with the task you have. In order to use the program:
- go to the official website cpuid.com.And download the archive with CPU-Z. It is better to use the version that you do not need to install on the computer, this version is the designation "No Installation".
- Next, you should unpack the program and provoke its launch in the executable file.
- In the main window of this program that opens, on the "CPU" tab, find the item "Cores". Here will be the exact number of the cores of your processor.
You can find out how many nuclei in the computer with the installed windows systemusing the task manager.
Reception number 3.
The actions of actions are:
- Run the dispatcher using the right side of the mouse on the panel quickly launch, Usually located below.
- A window will open, we are looking for the item "Run Task Manager"
- At the top of the dispatcher windows tasks There is a "Speed" tab, here in it, with the help of chronological loading of the central memory and the number of nuclei is visible. After all, each window and denotes the kernel, showing its download.
Reception number 4.
And one more opportunity to calculate the computer cores, for this you need any documentation on the computer, with the full list of component parts. Get an entry about the processor. If the processor refers to AMD, then pay attention to the symbol X and standing next to the figure. If it costs x 2, then it means you got a processor with two nuclei, etc.
In Intel processors, the number of cores is prescribed by words. If there is Core 2 Duo, Dual, then the kernels are two if Quad is four.
Of course, you can count the kernel, going on motherboard Through the BIOS, but is it worth it when the described methods give a completely clear answer to the question you are interested in, and you can check whether you really told you in the store and count how many kernels in your computer independently.
P.S. Well, that's all, now we know how to find out how many nuclei in the computer, even four more ways, and what to use is already your decision 😉

The central processor is the most important component of any computer that performs various calculations for any of running programs. One processor performs consistent data processing obtained from a separate program to one stream. The speed with which the data will be processed by the processor depends on its power, which is measured by the indicator called the clock frequency. In recent years, the increase in processor power by increasing clock frequency significantly slowed down, but another appeared perspective direction - Increase the number of nuclei in the processor crystal.
Multi-core makes it possible to divide the processing of data from the programs optimized for such processors, into several independent streams, which significantly speeds up their processing. If the application is not optimized for working with multi-core processes, it can be performed even slower than on a single-core processor with a greater clock frequency.
To find out how many nuclei has a computer processor in operating systems windows family Perform the following steps. 
This method can issue an error on Intel processors supporting Hyper-Threading technology (hyperpotoration). In such processors, each physical core can share data processing into two independent streams, as a result of which the operating system will recognize the doubled nuclei. That is, a processor having four physical kernels with support for Hyper-Threading technology will be displayed as eight-core.
Therefore, it is possible to determine the number of cores in the computer with the help of special utilities diagnostics. For example, free CPU-Z. The determination of the number of nuclei by this program is performed as follows. 
There are other ways to determine the number of processor cores. For example, through Windows Task Manager or BIOS ComputerBut in most cases it will be enough and those that we have described.
On the number of nuclei in central processor strongly depends total performance Systems, especially in multitasking mode. You can find out their number both with third-party software and standard methods Windows.
Most processors are now 2-4 nuclear, but there are dear models for gaming computers and data centers for 6 and even 8 cores. Previously, when the central processor had only one core, all the performance was in frequency, and work with several programs simultaneously could completely "hang" OS.
Determine the number of cores, as well as look at the quality of their work, you can using solutions embedded in Windows itself, or third-party programs (The article will consider the most popular of them).
Method 1: AIDA64
- this is popular program To monitor computer performance and conduct various tests. By paid, but there is a test period, which is enough to find out the number of cores in the CPU. The AIDA64 interface is completely translated into Russian.
The instruction looks like this:
Method 2: CPU-Z
CPU-Z - free programwhich allows you to get all the basic information about computer components. It has a simple interface that is translated into Russian.
To find out the number of cores with this software, just run it enough. In the main window, find at the very bottom, on the right side, item "Cores". Opposite it will be written the number of cores.
Method 3: Task Manager
This method is suitable only for users of OS Windows 8, 8.1 and 10. Perform these actions to find out the number of cores in this way:
Method 4: Device Manager
This method is suitable for all versions of Windows. Using it, it should be remembered that the information may be incorrect for some processors from Intel. The fact is that the CPU from Intel use Hyper-Threading technology, which divides one processor core into several streams, thereby increasing performance. But at the same time "Device Manager" Can see different streams on one nucleus as a few separate nuclei.
Step-by-step instruction looks like this:
Independently find out the number of nuclei in the central processor is easy. You can also simply see the characteristics of the documentation for the computer / laptop, if there is at hand. Or "thug" model processor, if you know it.
