CPU-z counterparts for Linux

Sometimes it becomes necessary to find out what components are in the computer. You can disassemble the computer and see the hardware used with your own eyes. But it is much easier to resort to specialized utilities that collect information about the system. For Windows, CPU-Z has become one of the most popular programs of this kind.

In this article, we have collected the best CPU-Z counterparts. For Linux, there are also programs that allow you to display information about the main nodes of the system: processor, motherboard, video card, memory and drives.

The best CPU-Z counterparts for Linux

1. CPU-X

Let’s start with the closest CPU-Z analog. The interface of the first tab is copied almost in its original form. Although there are a couple of minor changes. Instead of the processor revision, the temperature is indicated, and the processor load is also displayed in the frequency block. Information from sensors is not always read correctly, for this it is better to use other applications.

The rest of the tabs have more significant differences. For example, the cache not only duplicates the block of the first tab, but also performs a speed test. Speaking of the benchmark, it is also available here, but there is nothing to compare the result with.

The developer announced that he does not plan to develop the program in the future. Nevertheless, he will continue to update the databases and fix bugs. You can install CPU-X using the command:

sudo apt install cpu-x

2. Hard info

Despite the fact that there are more tabs in HardInfo, information about the system will not be able to get much more than CPU-X. Some of them are related to the software component, while others are related to network connections. We are interested in the section Devices and the very first tab A computer.

In the tab CPU you can find out the size of the cache and the supported instructions. You can also see a list of connected devices via PCI and USB buses. HardInfo is one of the few programs that allows you to find out information about memory modules (SPD).

The utility has several disadvantages. She could not see the NVMe drive, and also correctly read the sensor readings. It is hoped that in future versions these points will be corrected.

The test suite deserves a separate mention. With its help, you can find out the performance of your computer in various tasks and compare the results with other processors, although the most recent processor in the list was released more than 10 years ago (Core i7-920). To install HardInfo use the command:

sudo apt install hardinfo

3. CPU-G

Completes the list of CPU-G analogs. This program significantly lags behind the previous ones, both in terms of the amount of information and its accuracy. The last update was released a couple of years ago, so there are inconsistencies. The cache size is determined incorrectly, and virtual cores are counted as real. Needless to say, the program thinks Ubuntu is still running with the Unity shell. It makes sense to use CPU-G only on relatively old computers.

Due to the fact that the development has actually been discontinued, you will have to tinker a little with the installation. Install the required dependencies first:

sudo apt install libgirepository1.0-dev gcc libcairo2-dev pkg-config python3-pip python3-dev gir1.2-gtk-3.0

pip3 install pycairo PyGObject psutil dbus-python

After that you can download and install Deb package.

There are other programs for Linux to collect information about the system. For example, the KDE shell has its own tool, but its databases have not been updated for many years. Sysinfo, similar to HardInfo, is no longer developed and is not included in the repositories of the current versions of distributions.


There are not so many CPU-Z analogs for displaying information about the computer hardware, even for Windows. For Linux, at the moment there are only two actual utilities with a graphical interface, CPU-X and HardInfo. With console utilities, things are much better; through the terminal, you can find out the parameters of all the nodes of the computer.
