4 ways to check CPU speed

The speed of your CPU is in direct relation to the working speed of your processor and its speed to carry out a task. CPU speed is less important nowadays than before, thanks to the popularization of multi-core processors. However, it is always useful to check your CPU speed before purchasing new software, to ensure that your computer will be able to run it. It's also very handy to know where to find your actual CPU speed when you're overclocking your machine for better performance.


Method 1 of 4: Windows

Check CPU Speed ​​Step 1

Step 1. Open the System window

You can open this window quickly and in several ways.

  • Windows 7, Vista, XP: right click on Computer / My Computer in the menu To start up, then click Properties. In Windows XP, you may need to click the tab General after clicking on Properties.
  • Windows 8: right click on the menu To start up then click on System.
  • All versions: press the ⊞ Win + Pause keys.

Step 2. Find the Processor item

You can find it in the "System" section, below the Windows version.

Check CPU Speed ​​Step 3

Step 3. Take note of the processor speed

Your processor model and speed will be displayed. The speed will be indicated in Gigahertz (GHz). This is the speed of a single core of your processor. If your processor has multiple cores (most modern processors do), each core will run at that speed.

If your processor is overclocked, the current speed will not be shown here. Go to the next section to find the actual speed of an overclocked processor

Step 4. Find out how many cores your processor has

If you have a multi-core processor, the amount of cores will be displayed in this window. Having multiple cores doesn't necessarily mean that programs will run faster, but it can be a big advantage in the case of programs designed specifically for them.

  • Press ⊞ Win + R to open the "Run" window.
  • Write dxdiag and press Enter. Click Yes if you are prompted to check your drivers.
  • Look for the line Processor in the System tab. If your computer has a multicore processor, the quantity will be displayed in brackets after its speed (for example: 4 CPU's). This number will tell you how many hearts you have. Each heart will likely run at the same speed (there will always be slight differences).

Method 2 of 4: Mac

Check CPU Speed ​​Step 5

Step 1. Click on the Apple menu and choose About This Mac

Check CPU Speed ​​Step 6

Step 2. Look for the Processor row in the Preview tab

The theoretical speed of your processor will be displayed. Be aware that this speed may not be the current operating speed of your CPU. This is because your CPU slows down when not working to save power and increase its life expectancy.

Check CPU Speed ​​Step 7

Step 3. Download the Intel Power Gadget utility

This free utility will monitor your CPU and display its current operating speed. You can download it from the following website.

Unzip the file then double-click on the DMG file to install Intel Power Gadget

Check CPU Speed ​​Step 8

Step 4. Download and install Prime95

If you want to know the maximum speed of your processor, you will need to run your CPU at full speed. One of the most popular techniques for doing this is by using a program called Prime95. You can download it for free from mersenne.org/download/. Unzip the program then double-click on the DMG file to install it. Choose option Only a stress test when you start the program.

Prime95 was designed to calculate prime numbers and it will need all your CPU resources to do this job

Step 5. Find the speed of your processor

The second graph of the utility will tell you how fast your processor is. “Package Frq” will indicate your current speed depending on the task of your processor. This will surely be lower than the "Base Frq" which corresponds to the theoretical speed of the processor.

Method 3 of 4: Linux

Check CPU Speed ​​Step 10

Step 1. Open Terminal

Most of the utilities offered by Linux do not display the current operating speed of the processor. Intel has provided a tool called "Turbostat" which can help you. However, you will have to install it manually through Terminal.

Check CPU Speed ​​Step 11

Step 2. Write uname -r and press Enter

Take note of the version number which is displayed as (X.XX.XX-XX).

Check CPU Speed ​​Step 12

Step 3. Write apt-get install linux-tools-X.XX.XX-XX linux-cloud-tools-X.XX.XX-XX and press Enter

Replace X.XX.XX-XX with the version number you wrote down in the next step. Enter your administration password if prompted.

Check CPU Speed ​​Step 13

Step 4. Write modprobe msr and press Enter

The MSR module you need to run the utility will install.

Check CPU Speed ​​Step 14

Step 5. Open another Terminal window and write openssl speed

The OpenSSL speed test will start, causing your CPU to run at full speed.

Check CPU Speed ​​Step 15

Step 6. Go back to the first Terminal window and write turbostat

This utility will display a series of information about your processor.

Check CPU Speed ​​Step 16

Step 7. Find the GHz column

Each line corresponds to the current speed of each heart. The TSC column is the normal theoretical speed of your processor. This will help you see if your overclock has made a difference. The speeds will probably be low if you are not using your CPU.

Method 4 of 4: Windows (overclocked CPU)

Overclocking a CPU means increasing the voltage of a processor to get more power from it. Overclocking its components is very common in the world of computer fanatics because it allows them to get more performance from their hardware, but the procedure is potentially dangerous for the components. To learn more about the subject, see this article.

Check CPU Speed ​​Step 17

Step 1. Download the CPU-Z program and install it

It is a free utility that allows you to monitor the components of your computer. It was designed for those who want to overclock their machine and it will tell you the exact running speed of your processors. You can download it from the cpuid.com/softwares/cpu-z.html website.

CPU-Z will not install spyware or toolbars during the installation process

Check CPU Speed ​​Step 18

Step 2. Start CPU-Z

By default, you will find a shortcut on your desktop to start CPU-Z. You will need to be logged in as an administrator or know the administration password to be able to operate it.

Check CPU Speed ​​Step 19

Step 3. Start a task that will require a lot of CPU resources

The processor will automatically slow down when not in use, which means the speed you will see in CPU-Z will not match the maximum speed unless the processor is fully loaded.

  • A quick technique to get your CPU running at full speed is to run the Prime95 program. It is software designed to calculate prime numbers and it is widely used for performing stress tests on a computer. Download Prime95 from the mersenne.org/download/ website, unzip the files and click on Only a stress test when you run the program.
Check CPU Speed ​​Step 20

Step 4. Watch your CPU speed

The current speed of your CPU will be displayed in the "Core Speed" field in the CPU tab. Expect to see slight fluctuations in speed while running the Prime95 program.
