How to check CPU Core count on a Windows 10 PC [Guide]

A modern, fast CPU has more than one core. The more cores a CPU has, the faster it’s going to be. Normally, if you’re looking to buy a new laptop or build your own PC, you should look up the CPU specifications before you buy it. That said, if you ever need to check the CPU core count on a Windows 10 PC, there are multiple ways to do it. We’re going to list a few.

Windows Task Manager

Open Task Manager and go to the Performance tab. Select CPU from the column on the left and look under the graph. It will tell you both the number of cores and logical processors.

System Information

In Windows search, type System Information and open the app that shows up. Select Summary and scroll down until you find Processor. The details will tell you both how many cores and logical processors you have.

Command Prompt

This may not be the easiest way to find the CPU core count for a system since you have to remember a command to do it, but it does work.

‘); if (navigator.appVersion.indexOf(“Mac”)!=-1) document.write(”);

Open Command Prompt and run the following command;

WMIC CPU Get DeviceID,NumberOfCores,NumberOfLogicalProcessors

The command will return both the core count and the logical processors that you have.

Third-party app – CPU-Z

If the built-in options on Windows 10 don’t do the trick for you, and you want to use a third-party app, we recommend using CPU-Z. We’ve recommended this tool for lots of other things like checking whether you have Kaby lake or Skylake processor.

Run the app and at the bottom, you will see core count next to Core, and the number of logical processors next to the Threads field.


We mentioned that if you’re buying a new laptop or building your own PC, you should look up the core count for the prospective CPU you’re getting. It’s pretty easy to do; go to Google, enter the name, make, and model of your processor and append the word ‘Specs’ at the end. You will get tons of websites reporting, and even benchmarking the performance of the CPU. Go to the manufacturer’s website and check how many cores and logical processors it has. The specs will be as accurate as any other place you look them up on.

Hardware information like this can’t really be faked. You may have heard of some manufactures exaggerating how fast a product is but the exaggeration doesn’t extend to the specs that Windows 10 can report.
