Having received a question, how to find out how many bits are 32 or 64 or how to find out how many bits are on a computer, you will certainly want to ask: “What bit do you want to find out?” First, decide whether you want to know the bit depth of the processor or the version of the operating system that is designed to work processor with this bit. If you want to know the bit depth in order to work with programs (install a new one, update the driver) - we are looking for the properties of the operating system. If you are going to update the PC hardware (for example, expand the amount of RAM) - we find out the properties of the main device - the processor.
How to find out the bitness of the system
If you decide to update the driver or you need to find out whether your computer can handle a complex program, you just need to determine the properties of the system. This is a characteristic of the written software for a certain bit of the processor. To find out the bitness of the operating system, the easiest way is to open the "Properties" window. Find the Windows icon (a) on your keyboard. After clicking it, the Main menu will open on the screen, in its right side we find the "Computer" command, but do not open the window, but right-click, select "Properties" from the context menu commands that appear.
We get the result - the Properties Window.
Tips for those who like to use the keyboard
You can exit to this window in a more convenient way - using the special keys. Combination of Win icon and Pause / Break button. The same window will open where you can find out the bitness of the operating system. There is another way to go to System Properties. But it is more convenient for advanced users (who are not afraid of the Command line and the black-and-white interface. In the Main menu, on the right side, we find the Run command, type cmd.exe in the text input field, and in the window that opens, the systeminfo command. How to determine the bitness of the system ? This parameter will be listed next to SystemType.
The question of how to find out how many bit system is solved? Then let's move on to a more complex characteristic of your computer.
How to find out the bitness of the processor
The bit depth of the processor is a property of your hardware, the ability of the processor to process a certain number of units of information at the same time. Users determine the processor bit exactly when they want to update a PC device. For example, add RAM.
A 32-bit processor will not handle more than 4 GB of RAM management.
To find out the health of your processor, there are special programs. For example, the (absolutely free) utility CPU-Z. We will limit ourselves to the simplest way - it does not require additional installations. Open the Task Manager (press the Ctrl key, do not leave, add Alt, also, without lifting your fingers from these 2 keys, add Delete). Find the Performance tab, the CPU Load History panel:
If there are several windows on this panel (we have 8 in our example) - almost always, you are dealing with a 64-bit processor. Single-core processors are now practically not found live, here, for clarification, you will still need a special program (we have already mentioned CPU-Z).
Let's imagine that we have a computer and not a single accompanying document to its "guts". Naturally, it is very difficult to find out the exact characteristics of the contents of the system unit. And then suddenly it was necessary to get information about the bitness of the processor. How to be?
How to find out the bitness of the processor and OS - a few simple rules
There are many tricky ways to figure out how many bit processor sits in the system unit. The elementary method does not require unpacking third-party software, but it cannot boast of the accuracy of the results. To use the standard tools of the Windows family, you need to open the Task Manager by holding down three buttons at once - Ctrl + Alt + Delete. In the pop-up window, go to the "Performance" category and pay attention to the "Chronology of CPU utilization". The number of these windows indicates the number of cores in a particular processor. If there are two or more windows, the processor is 64-bit, because dual-core processors cannot have a different bit depth.
A different approach is needed to the old-timers - you will need additional software. For the result to be accurate, you need to download 2-3 utilities and compare their readings. But first things first. The CPU-Z program does not load with an intricate interface, for which it is very loved by computer scientists. The easiest way is to download it from the official resource of the program - this mini-utility is absolutely free and takes up very little virtual space. After unpacking and running CPU-Z, you need to go to the "CPU" category, which tells in detail about the processor. The line "Instructions" will contain a rather mysterious cipher of 7-8 sets of Latin letters and numbers. We are only interested in the last abbreviation: if “EM64T” appears in its place, the processor is 64-bit. In all other cases, it has 32 bits.
Another simple utility is AIDA64. True, the "golden hands" of the programmer fraternity have not yet hacked it, and the utility remains paid to this day, graciously allowing you to use it in a trial mode only 30 days after installation. Taking it from the official site, deploying and running it, you need to go to the "Motherboard" category, and from there - to the "CPUID" line. Where it says "Instruction sets", and you can find out how many bits in the processor - 64 or 32.
Encyclopedic minute
What is bit depth in general, what is it, and why might you need to know it?
Determination of the bit depth is necessary for those who intend to upgrade their beloved computer and do not know how much RAM will be needed for its normal operation. The bit size of the processor (or bus) is usually called the number of bits that the processor can process simultaneously in a time slice. The concept of bit depth is applicable to the details of computing, external or measuring gadgets: computer data buses, their processors, etc. 32-bit (x86) operating systems can handle up to 4 GB of RAM and are extremely popular in today's IT world. 64-bit OS (x64) support many times more RAM and can work much faster than 32-bit sisters, provided the software is selected strictly for 64 bits.
An x86 OS will easily fit on an x64 processor, but an x86 processor will never support a 64-bit OS. There is also a lot of software tailored to a certain bit depth (of course, creating a lot of compatibility problems). It is for the sake of optimizing the operating system and all its components that users try to find out the bit depth of their processors.
Kondratyev Matvey gave another solution in the comments: Start-> Run-> cmd.exe, then enter the command systeminfo and looking for the line System Type.
One of the most important parts of a computer is a processor - CPU (Central Processing Unit) - it is actually a "brain" that processes the incoming information in the form of program code. Simply put, this is a microcircuit that processes information and controls all computer devices: motherboard, keyboard, RAM, executes program commands, etc.
One of the main parameters of any processor is its bitness- the number of bits that it will process through the set registers in one clock cycle, exchanging with the RAM. Currently, there are processors with 64 - bit and 32 - bit capacity (or rather, it 's quite rare now to find 32 - bit). They are marked as follows:
- 32-bit - labeled as x86;
- 64-bit ones are labeled as x64.
Quite often the following questions arise: which is better than a 64-bit or 32-bit processor and why, and which RAM to install or which operating system is better -32 or 64 bit? And it all comes down to the question:
How to find out the bitness of the processor?
The simplest solution is a utility CPU-Z- a utility that collects all information about the main devices of the computer. СPU Z can be downloaded from the site for free.
In the upper right corner, you can download the latest version from the manufacturer in English. Download the file and run it. Those who wish to work with the English original. But there is also this utility in Russian.
cpu z in Russian
You can download cpu z in Russian, for example,.
You can download both a 32-bit version and a 64-bit one - whatever you like. We downloaded the program to our computer and run the executable file (after unzipping it). After starting, we see such a window:
On the CPU (central processing unit) tab, in the line Instruction set look, if there are 64 digits, then it is 64-bit. Otherwise -32-bit.
In this case, the EM64T instruction indicates the bit width.
The better a 64-bit processor
If the computer has a 32-bit processor, it is technically impossible to access more than 4 GB of RAM. Those. even if you have 6 GB of RAM installed, only 4 GB will be used.
If 64-bit is installed, then more than 4 GB of RAM can be installed. But in this case, the operating system must also be 64-bit. Because even with a 64-bit processor, if a 32-bit operating system is installed, you get the same result - no more than 4 GB of RAM will be used. Hence the simple conclusion:
To use more than 4GB of RAM, you need a 64-bit processor and a 64-bit operating system.
And how to find out the bit capacity of the installed operating system?
Easy! Click in the lower left corner Menu —Control panel I am- system and safety —System... Or My computer, select with the right mouse button Properties.
This tab contains basic information about the computer. As you can see from the picture, everything is fine here - the required operating system is installed.
And for a snack, what the inquisitive mind of a lazy person is capable of.

The bit width of the CPU is the number of bits that the CPU is able to process in one way. Previously, 8 and 16 bit models were in use, today they have been replaced by 32 and 64 bit models. Processors with 32-bit architecture are becoming less and less common. they are quickly being replaced by more powerful models.
Finding the processor bit capacity can be a little trickier than expected. To do this, you will need either the ability to work with "Command line", or third-party software.
One of the easiest standard ways to find out the bitness of the processor is to find out what bit the OS itself is. But there is a certain nuance here - this is a very imprecise method. For example, if you have a 32-bit OS installed, this does not mean at all that your CPU does not support 64-bit architecture. And if the PC has a 64-bit OS, it means that the CPU is 64-bit.
To find out the architecture of the system, go to it ... To do this, just right-click on the icon "My computer" and select from the drop-down menu ... You can also right-click on the button "Start" and in the drop-down menu select "System", the result will be the same.
Method 1: CPU-Z
Is a software solution that allows you to find out the detailed characteristics of the processor, video card, computer RAM. To see the architecture of your CPU, you just need to download and run the software you want.
In the main window, find the line "Specifications"... At the very end, the bit depth will be indicated. It is denoted like this - "X64" Is a 64 bit architecture, and "X86"(rarely comes across "X32") Is 32 bit. If it is not listed there, then see the line "Set of instructions", an example is shown in the screenshot.
Method 2: AIDA64
Is a multifunctional software for monitoring various indicators of a computer, conducting special tests. With its help, it is quite possible to find out any characteristic of interest. It is worth remembering that the program is paid, but it has a demo period, which will be quite enough to find out the bit capacity of the central processor.
Instructions for using AIDA64 looks like this:
Method 3: command line
This method is a little more complicated and unusual for inexperienced PC users, compared to the first two, but it does not require the installation of third-party programs. The instruction looks like this:
It is quite easy to find out the bit depth on your own, but you should not confuse the bit depth of the operating system and the central processor. They depend on each other, but may not always be identical.
Today, almost everyone knows that 64-bit Windows 7 and Windows 8 are faster than 32, especially for games.
If you currently have x32, then why not try your luck with x64 and reinstall Windows.
Just before you do this, you need to find out what bit depth of your processor, regardless of the installed windows 7 or windows 8.
Why? If your processor does not support 64-bit, then Windows should not be changed - there will be no sense.
To determine the maximum bit depth, you need to use special programs.
Check the processor bit capacity with the CPU-Z program
The CPU-Z program can be said to be the best of the best to test the processor of your computer or laptop.
She will tell you almost everything about it, but on one of my laptop, I could not find out what the bit of the processor was (Intel (R) Core (TM) 2 Duo CPU T5750).
On the second, it was easy to identify. Who wants to try it, download, define.
It is small, completely free and in Russian, so you don’t lose anything, except for a few minutes of time.
Find out the maximum bit capacity of the processor using the securable utility
With the securable utility, you have the ability to quickly see what bit depth your processor is and more.
You will also be able to find out hardware support for "virtualization" system resources and security information.
Although this is a tiny creature, only in English (created by Steve Gibson) you will understand everything immediately after launch (no installation required)
Securable - not only will tell you whether the processor is 32 or 64 bit.
As stated above, you will find out if it supports DEP hardware protection and hardware virtualization.
If you see 64 in the utility window, it means that your system can work in much faster 64-bit versions of operating systems from Microsoft: Windows XP, Vista, 7, 8, 8.1, 10.
Only, besides the fact that you determine what bit of the processor, you need to learn something else.
32-bit drivers cannot be used in the 64-bit kernel of the operating system.
Therefore, if you are planning to upgrade to 64-bit Windows, you should find out if 64-bit drivers are available.
If your system's hardware turns out to be incompatible with 64-bit, you're wasting time. Good luck.
