Find the CPU (processor) speed and model under Linux

In today’s rapidly evolving digital landscape, understanding the performance capabilities of your Linux system is more vital than ever. Whether you’re a software developer testing an application, a sysadmin maintaining servers, or an everyday user simply looking to optimize your system performance, knowing your CPU speed and model under Linux is a key piece of the puzzle. Today, we’ll delve into the process of finding your CPU speed and model on the top three Linux distributions: Ubuntu, Fedora, and CentOS.

How to Find CPU Model, Speed, and other Details


Ubuntu, being one of the most popular Linux distributions, is renowned for its user-friendly interface. Identifying your CPU’s speed and model on Ubuntu is fairly straightforward.

To begin, open your terminal using the shortcut Ctrl+Alt+T.

To uncover the model of your processor, type the command:

lscpu | grep "Model name"

This command utilizes the lscpu utility, piping its output into the grep command to filter and display your processor’s model name.

Next, to determine your CPU speed, use:

lscpu | grep "CPU MHz"

This will display the current CPU speed in MHz. Remember, 1000 MHz equals 1 GHz.


Fedora, another popular Linux distribution, operates quite similarly to Ubuntu when it comes to determining CPU information. To start, open your terminal.

Just like in Ubuntu, use the following command to identify your CPU model:

lscpu | grep "Model name"

For the CPU speed, use:

lscpu | grep "CPU MHz"


CentOS, known for its robustness and stability, is frequently used for servers. Like Ubuntu and Fedora, CentOS uses a similar approach to extract CPU data.

Start by opening your terminal. The commands to find your CPU model and speed are the same as Ubuntu and Fedora:

lscpu | grep "Model name"

And for the CPU speed:

lscpu | grep "CPU MHz"

You now have the knowledge to efficiently identify your CPU speed and model on these top three Linux distributions.

Why CPU Knowledge Matters

Knowing your CPU’s speed and model is essential for a multitude of reasons. For developers, it’s crucial to understand the processing capabilities of a system for testing and optimizing software. For sysadmins, knowing the CPU’s speed and model aids in troubleshooting and evaluating system performance. Even everyday Linux users can benefit from this information when choosing new software to install or when upgrading their hardware.

The dynamic world of Linux is vast and multifaceted. However, understanding how to access key pieces of information about your system doesn’t have to be a daunting task. Armed with the above tips and commands, you’re well on your way to becoming a Linux power user, optimizing your system performance, and making the most out of your Linux machine.
