How to find out which nuclear processor. How to enable all processor cores

For modern operating systems such as Windows 7 or the newly-minted Windows 8.1, one or two processor cores in system unit is no longer enough. Therefore, manufacturers strive to add as many cores as possible to modern PCs. but also save on price. Basically, now they produce two, four-core notebooks and four-core processors for computers.

Sometimes, in the process of mastering personal computer or laptop, the user has a question R12; how many cores are there in his computer? Many want find out how many cores processor in his computer.

How to find out? This is very easy to do. There are programs with which you can find out many parameters of the system, such as a video card, sound card, volume random access memory, temperature and so on. For these purposes, the Everest program, or as it used to be called Aida, is very well suited. There are separate programs with which you can find out only about the video card or only about the processor. But in our case, none of this is required. We will find out how many cores in our computer are built-in means of Windows.

So, let's begin!

METHOD 1.

To do this, go open the "START" menu and look for the "Computer" item in the right side of the menu and click on it with the right mouse button

Thus, we call the window where you need to select the item "Properties"

We get into the properties of the computer, where we can view the size of the RAM, the type of processor but not the number of cores, but to find out how many of them are in the processor, we need to find the line "Device Manager" in the left side.

We go into the device manager and find the line "Processors". To expand it, click on the small triangle opposite the "Processors" item

And we see the number of cores in the processor. I found out that I have four cores. You can have two and three and four and six.

METHOD 2.(even easier)

We need to start the task manager, for this we right-click on the panel quick launch and in the window that opens, select the item "Start Task Manager"

In the top panel of the manager, select the "Performance" tab and look at the chronology of loading the central memory. Each separate window shows the kernel loading. That is, I have 4 windows and therefore four cores.

Now you know how simple find out how many cores on your computer!

CPU is an essential component of any computer that performs various calculations for any of running programs... One processor performs sequential processing of data received from a single program in one thread. The speed at which the data will be processed by the processor depends on its power, which is measured by an indicator called clock frequency. In recent years, the growth of processor power due to an increase in clock frequency has slowed down significantly, but another promising direction has appeared - an increase in the number of cores in a processor crystal.

Multicore allows you to divide the processing of data from programs optimized for such processors into several independent threads, which significantly speeds up their processing. If an application is not optimized for multi-core processes, then it may run even slower than on a single-core processor with a higher clock speed.

To find out how many cores a computer processor has in operating systems of the Windows family, follow these steps.

This method may give an error on processors Intel that support Hyper-threading technology. In such processors, each physical core can split data processing into two independent threads, as a result of which the operating system will recognize twice the number of cores. That is, a processor with four physical cores with support for Hyper-threading technology will be displayed as eight cores.

Therefore, you can more accurately determine the number of cores in a computer using special utilities diagnostics. For example, free CPU-Z... Determination of the number of cores by this program is performed as follows.

There are other ways to determine the number of processor cores. For example, through the Windows Task Manager or Computer BIOS, but in most cases the ones we described will be enough.

In some cases, you will need to know how many cores the processor has. As a rule, when buying a new computer, you might think about checking the manufacturer's specifications. If you prefer Windows 10, there are a few simple methods you can use to check the number of cores.

In an era of modernization, when Intel is looking forward to the upcoming release of new generations of Cannon Lake, Kaby Lake and Coffee Lake processors, it is much easier for the user to afford a computer with four cores. It's time to find out about the power of the processor you are using.

Before we start pointing out how to detect the number of cores in latest version system, it is important to collect information about what it is.

What does the kernel refer to?

A computer includes a number of important components that are generally referred to as hardware. Among them, the most important part is the processor (central processing unit). It is the first to receive information to perform a computational operation and contains a set of instructions. Now it's time to learn about the term "core".

On a note! If a processor has only one set of instructions, we call it single-core.

Over the years, Intel has made huge changes to the processor instructions. As we said earlier, its name depends on their number. In the case of two sets of instructions, we call the processor dual-core or Dual Core. Likewise, 4 sets are Quad Core, 6 sets are Hexa-Core. The latter is Octa-Core as it contains 8 instruction sets. Now we know what cores are, so let's move on to checking their number in the CPU.

Exist different methods definitions of kernels, and we will examine them in turn.

You can use:

"Task Manager";
system information;
Google search;
or third party software.

To clearly understand the whole process and avoid mistakes, we will discuss each method step by step.

Methods to check the number of cores in a CPU on Windows 10

Method 1: Using System Information

System Information - Alternative option, which allows you to check the number of cores in the CPU without involving additional software... For this reason, the steps are as follows:

Step 1. Click the "Start" button on your computer and type "information" in the search box. Select "System Information".

Step 2. The right pane contains a list of items that describe each part of the PC. Test them slowly until you find a processor listed. In any case, if you have two processors, then you will see them separately. Take a close look at the value and find the number of cores (see screenshot).

Method 2. Using the "Task Manager"

Among all the procedures for checking the number of cores in a CPU, the fastest is through the "Task Manager". Just follow the steps below.

Step 1... You can start Task Manager in two ways:

Step 2... The Task Manager has several sections. Switch to the "Performance" tab. On the left sidebar, you will see graphical metrics for CPU, Memory, Ethernet, Disk 0, Disk 1, and more.

Step 3. Click on the "CPU" parameter and a graph with additional information will open on the right side of the panel.

Step 4. Below you will notice base speed metrics, sockets, cores, etc. So, look for the number next to the cores. For example, the bottom photo shows the number 2, which means that the PC has a Dual Core processor.

Typically, Task Manager shows only one chart, but you can change the way it is displayed. For this:

You will be happy to find that there is no need to change the schedule in Windows 10, as it automatically reports the number of cores, sockets and logical processors present in the system.

On a note! In addition, the "Task Manager" also provides information about caches like L1, L2 and L3. In some cases, the computer's CPU uses special caches to provide better computing performance.

Method 3. Using Google search

Google search also helps you discover the number of cores in a processor only if you know the model number. In the absence of proper information, use the "Task Manager" or system information (see above methods).

For example, we googled core - i34005U. By examining the returned results, you will receive information about the processor specification. It lists every detail in detail. Find the core and you will see your number.

Method 4. Third-party applications

You can also use third-party programs to find out detailed information about the processor. They are mostly free. Along with details about the processor, applications will also inform you about support for virtualization, SSSE3, etc. They are very effective and equally useful when you need to find information about a device.

The Internet is full of collections of different verification tools motherboard as well as processor parts. The two most popular programs are Speccy and HWiNFO. Both work very well and provide almost all hardware data.

Let's consider how to find out information about the processor using the Speccy program as an example:

The above simple methods will help you find out the number of cores in the processor. Plus, it doesn't take long.

On a note! It's nice to know that 32-bit Windows system 10 supports up to 32 cores. If you choose 64-bit, then the device can support up to 256 cores.

Conclusion

When using a computer, you should understand its details at least superficially. This is really useful for determining the performance of the device, as well as in terms of professional work. You should definitely know how many cores your processor has. It's good that Windows 10 makes searching easier. As a rule, we feel the need for simple methods data discovery. So, try using the above methods to check the number of cores in the CPU. It's good if you know more options.

Video - How to find out how many cores are on a computer

Hello! Sooner or later, almost all users have a question - how to find out how many cores are in a computer? (and for a good core, specifically in the processor) and what pitfalls are there in this seemingly simple enough task. This note is a logical continuation of the instructions on whether your PC or laptop is in series.

Why did I decide to raise this issue? - I understand that there are enough quite detailed notes on the network about ways to determine the number of processor cores, but almost all of them combined logical and real ones.

In fact, having pebble with two cores, you will think that you have full four cores and there will be a misunderstanding - why is a modern toy stupid? Productivity is abundant ...

Currently, the number of threads processed can be greater than the number of physical cores. This allows you to use unused by the kernel in currently processor instructions and in theory to increase performance. Such a virtual core gives incomparably less performance gain, but is defined in the system as a logical processor. This note was written to help you figure out these nuances.

It so happened that to find out the number of available threads in the system is almost 100,500 ways. As soon as we talk about physical cores, the number of options is seriously reduced (and most authors present these very logical cores as physical, which is a gross mistake).

I decided to divide the note into two small blocks - in the first we will determine the number of cores using standard Windows tools, and in the second we will try various utilities that will answer our questions.

How to determine how many cores in a processor using standard Windows tools

Have standard tools there is a huge advantage - they are already installed in the system and can be used immediately. However, most of the tools built into the system tell us about the number of threads, which in some cases can distort our idea of the number of cores in a processor (with Hyper Threading from Intel or SMT from AMD)

Method 1. Task manager

One of the most simple ways determine the number of physical processor cores - this is to start the task manager (this is done by a combination CTRL keys+ SHIFT + ESC), go to the "Performance" tab, select "CPU" on the left side and look at the number of cores as in the picture below (logical processors are the same threads)

Unfortunately, such a task manager has been present since Windows 8 and in the seven familiar to many, this way it will not work, there we will see only threads

Method 2. System Information

This method works for everyone Windows versions(unfortunately I can't check on Windows XP, and who uses it in 2k17). Windows has a tool called System Information. It displays detailed information about our computer, including helping to find out the number of physical cores in the processor. To start it, open the Run command (the easiest way is with the WIN + R keyboard shortcut) and type the command ...

... click OK and wait for the window to load.

Everything is extremely simple here, in the line "Processor" the number of cores and threads will be written, as well as a lot of other useful information.

Although standard methods allow you to determine how many cores in a processor, they provide too little information for a sophisticated user - there are specialized applications specifically for them.

How to see how many cores on a computer with third-party utilities

If you want to squeeze out the maximum information about your processor, then there are specialized utilities for this (if you still do not know what processor you have in your system, then be sure to read it). It is these programs that we will now consider ...

Method 1. CPU-Z

The CPU-Z program is probably the best when it comes to viewing the characteristics of the central processor, without exaggeration. I prefer the portable version, which does not require installation - download and use it. You can download it on the official website:

After launch, the number of processor cores can be viewed on the "CPU" tab in the "Cores" line (and Threads is the number of threads)

In most cases, the number of cores coincides with the number of threads, virtual cores are usually the lot of the most expensive solutions (but there are exceptions)

Method 2. HWiNFO

The following utility helped us and accurately displayed, without any problems, it will determine the number of cores and threads in the system. HWiNFO has several editions (32 and 64 bit versions), you need to download for the bitness of your operating system, the link to the download page is, as always, below (if you have doubts about the system capacity, download HWiNFO32 - it will run everywhere)

I recommend using the portable version. Well, after launch, the "System Summary" window will open to us where next to the processor name you will see the number of physical and logical processors (Cores and Logical, respectively)

In general, the HWiNFO application gives information not only about cores and threads, but also shows itself a very visual report about giblets your computer

Method 3. AIDA64

The next program that will help you find out how many cores a processor has is AIDA64 (formerly Everest, otherwise they often ask me why I never include it in my list). The product is commercial, but there is trial period- you can download it from the official site (we are interested in the Extreme version)

By the way, there is also a portable version. We launch the application, on the left side we go to “Computer”, “Summary information”, and on the right side in the “System board” block in the line “CPU type” in the example it says QuadCore - this means that I have a processor with four cores in the system. In general, if it is stressful with English, you can always use an online translator.

AIDA64 is probably one of the most inconvenient applications for determining the number of cores on a computer, but such a monster simply could not be excluded from this top

Method 4. Piriform Speccy

In conclusion, I want to tell you about the utility from the developers of the legendary Ccleaner - this is how many guessed Piriform Speccy. Appointment of this application- to tell in as much detail as possible about each component of your system (including the number of cores and processor threads). The utility has free version and you can download it from the official site.

We launch the application and in the left part we find the item "Central processor" - information about our CPU will open. In the kernel line, we will see the number of processor cores (just below information about threads)

Piriform Speccy is probably one of the best apps to collect information about the computer, but the lack of a portable version saddens me a little

Conclusions about all the ways to find out how many cores are on a pc

Well friends, it's time to wrap up and take stock. After reading this post, you know how to find out how many cores are in a computer ... however, there is another simple way - if you know your processor model, you can find information about it on the official website. Since there will be information about the number of cores and threads in the system.

Despite the fact that in the store the buyer can see the characteristics of the purchased product, in practice there are cases when unscrupulous sellers deceive gullible users. One of such machinations is the indication of the wrong quantity.Thus, you can greatly inflate the price and sell outdated goods at a higher cost. To avoid this kind of deception, you need to understand how to find out how many cores are on a laptop.

Without software

Many modern laptops are sold without an operating system preinstalled. So programmatically check necessary information will not work. How do you know how many cores are on a laptop in this situation?

First, there are mini stickers. Any official manufacturer computer technology pastes the laptop with special stickers that confirm the licensing of the equipment (few people know, but without them, even a broken PC may not be taken to your service). Check the availability of such a sticker. For example, the "Intel Inside CORE I5" sticker would indicate a quad-core processor.
Sticker with technical characteristics... One more "external sign". Similar to the previous case, the manufacturer applies a sticker to the laptop, which will indicate the RAM, HDD, video card and specific processor model.
Another way to find out how many cores are on a laptop, not including it, is to ask the seller for technical documentation on specific model... Everything will be indicated there. You will not be denied in bona fide stores.

Windows

In work

Another way to find out how many cores on a laptop also uses the built-in Windows tools... Press Ctrl + Alt + Del and launch the task manager. You can also do this by right-clicking on the bottom panel (with the "Start" button).

After that, go to the "Performance" tab. A screen with a graph of the RAM load will appear in front of you, and in the upper part of the window you can see several graphs with the processor load. Each of them corresponds to a separate core. Actually, this will also answer the question: "How do you know how many cores are running on a laptop?" Even when completely inactive, each graph should show at least one percent load.
