Your CPU speed determines how fast jobs can be performed by your process. CPU speeds matter less than they did before, thanks to the advent of multi-core processors. Nevertheless, it can not be useless to check your CPU speed when investing in a brand new program to make sure your computer can manage it. When you’re overclocking for better functionality it’s also very helpful to learn the best way to test the CPU’s true speed.

How to check CPU speed in Windows

1 Open the System properties window. There are many ways that this window can open instantly.

Open the System properties window

  • Windows 7, Vista, XP – Right-click on Computer/My Computer in the Start menu and select “Properties”. In Windows XP, you will need to click the “General” tab after choosing “Properties”.
  • Windows 8 – Right-click on the Start button and select “System”.

All Variations – Press Win + Pause.

2 Find the “Processor” entry. This is located in the “System” section, beneath the Windows version. Note the cpu speed. Your chip model and speed will be shown. The speed is measured in gigahertz (GHz). This really is the speed of a single core of your chip. In case your processor has multiple cores (most modern chips do), each core will be this rate.
The particular rate might not be shown here in case your cpu is overclocked. See the next section for details on finding your real overclocked rate.

Find the "Processor" entry

3 Check just how many cores your processor has. When you are in possession of a multi-core processor, how many cores will never be exhibited in this window. It could be a large increase for applications designed for this, although multiple cores does not always mean the applications will run faster.


    • Press Win + R to open the Run dialog box.

Type dxdiag and press Enter. Click Yes if prompted to assess your drivers.

  • Locate the “Processor” entry in the Machine tab. If your computer has multiple cores, you’ll begin to see the number in parentheses following the rate (e.g. 4 CPUs). This will inform you exactly how many cores you’ve got. Each core runs at about exactly the same rate (there will often be really small variations).


How to check Overclocked CPU in Windows with CPU-Z

Overclocked CPUs are central processing units that have had their voltages modified to generate more power. Overclocking is popular among computer enthusiasts, as it lets you obtain more bang for your buck, but it could possibly damage your parts.

1 Download and install CPU-Z. It is a freeware utility that tracks the components in your pc. It’s designed for overclockers, and will report the precise rate that the processors are operating at. You are able to download it from here.

2 Run CPU-Z. By default, there will be a shortcut on your own desktop computer to start CPU-Z. Possess the administrator password to be able to run it, or you are going to need to be logged in as an administrator.

3 Start a CPU-intensive task on your own desktop. Your processor will automatically slow down when it isn’t being used, so the rates you see in CPU-Z WOn’t show the full speed unless your processor is working hard.

A fast strategy to get your CPU maxed-out is to run the Prime95 application. This is a program built to calculate prime numbers, and is employed by many to perform stress tests on a computer. Download Prime95 from here, unzip the program files, and choose "Just Stress Testing" when you operate the program.
4 Check your CPU speed. Your present CPU speed will undoubtedly be shown in the “Core Speed” area of the CPU tab. Expect to see small changes as your personal computer processes the Prime95 program.

How to check CPU speed in Mac

1 Click the Apple menu and select “About This Mac”.

Click the Apple menu and select "About This Mac".

2 Locate the “Processor” entry in the “Overview” tab. This will definitely show the advertised speed of your chip. Note that this might not function as the speed your CPU is really running at. This really is because your CPU slows itself down when it’s not working to save energy.

Locate the "Processor" entry in the "Overview" tab.

3 Download the Intel Power Gadget. This free utility report the particular operating speed and will monitor your CPU. It is possible to download it at no cost from here. Unzip the file and then double click the DMG file to install Intel Power Gadget.

 install Intel Power Gadget.

4 Download and install Prime95. In the event you’d like to observe the maximum rate of your chip, you will need to put a hefty load. Among the most famous methods to do this is using a program called Prime95. It is possible to download it at no cost from here. Unzip this program and then double click the DMG file to install it. Select “Just Stress Testing” when you start the program. Prime95 is intended to calculate prime numbers, as well as in doing this will max your CPU out.

5 Find your processor speed. The second graph in the gadget will show your processor speeds. The “Package Frq” is the current speed depending on what your processor is working on. This can likely be lower than the “Base Frq”, that is the advertised rate of the processor.

How to check CPU speed in Linux

1 Open the terminal. Most applications available on Linux don’t show the actual rate that the chip is running at. Intel has released a tool called turbostat that you can use to assess. You will have to install it manually.

Open the terminal

2 Type uname – r and press Input. Note the version number that is displayed (X.XX.XX-XX).

uname - r

3 Type apt-get install linux-tools-X.XX.XX-XX linux-cloud-tools-X.XX.XX-XX and press Enter. Note that X.XX.XX-XX is your version number from step 2. Type in admin password if you will be asked to.

4 Type modprobe msr and press Enter. This may install the MSR module that you’ll have to run the software.


5 Open another terminal window and type openssl speed. This will definitely start the OpenSSL speed test, that will push your CPU to the maximum.

6 Return to the first terminal window and type turbostat. Running this can show many different readouts about your central processing unit.


7 Look in the .GHz column. Each entry is the specific speed of every core. The TSC column is the speed reported normally. This permits you to determine the difference your overclock is making. If you aren’t pushing your CPU with a procedure, the rates will not look high.
