How to Check How Many Threads Your CPU Has

A CPU core is a physical component within your CPU chip. A thread is a logical CPU within each core. Most modern CPUs have multiple cores, and each core typically supports at least two threads. This configuration is referred to as Multicore Multithreading (Hyper-Threading).

Multi-threading lets a single-core CPU handle two tasks at once by rapidly switching between them.

How to Check CPU Thread Count in Windows

In Windows 10/11 and Server, open Task Manager (Ctrl+Shift+Esc), go to the Performance tab, and click CPU on the left side.

Under the CPU graph, you will find both the core count and thread count (labeled as logical processors or virtual processors) for your CPU.

This system has 8 physical cores, but the OS sees 16 virtual CPUs thanks to Hyper-Threading. This allows it to split the workload among 16 threads, boosting performance for certain tasks.

How to Check CPU Thread Count in Linux

In Linux you can use lscpu command to find the thread count of your CPU.

lscpu

Running lscpu on my Desktop produced the following output:

Observe the number under the CPU(s) directive (16 in this example); that indicates the count of logical processors or the thread count of your CPU.

You can gain even more understanding by examining the parameters such as Socket(s), Core(s) per socket, and Thread(s) per core. The Socket(s) parameter indicates the number of CPU chips attached to your motherboard.

In this example, we have one CPU chip with 8 cores. Each core has two threads, resulting in a total of 16 threads (logical processors).

In addition to this information, the lscpu command also displays details such as CPU model, frequency, cache size, and more.
