Proven CPU-Z analogues for Linux

Sometimes there is a need to find out what components are in the computer. You can unwind the system unit and personally verify what is inside. But a more correct and faster solution is to use a utility that collects information about the system. For Windows, one of the most popular programs of this kind has become CPU-Z.

Next, let's look at the best analogues of CPU-Z. 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.

CPU-X

The closest analogue of CPU is Z. The interface of the first tab is copied almost exactly. But there are some minor changes. For example, the temperature is indicated at the site of the processor revision, and the processor load is displayed in the frequency block. The information from the sensors is not accurately read every time, for this it is better to use other tools.

The other tabs have more differences. So the cache not only duplicates the block of the first tab, but also conducts a speed test. There is a benchmark here. The developer stated that he does not plan to develop the program in the future. But still, he will continue to update databases and fix bugs. You can install CPU-X using the command:

$ sudo apt install cpu-x

HardInfo

There are more tabs in HardInfo, but the utility gives out useful information no more than CPU-X. Some of them relate to the software component, the other to network connections. Go to the Devices tab and then to the Computer.

In the Processor tab, you will find out the cache size and supported instructions. You can also view 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).

Note the disadvantages of the program. She does not see the NVMe drive, and does not read the sensor readings correctly. But perhaps in future versions these points will be fixed.

There is a set of tests here. With its help, you can find out the computer's performance in various tasks and compare the results with other processors, although the most "fresh" processor in the presented list came out more than 10 years ago (Core i7-920). To install HardInfo, use:

$ sudo apt install hardinfo

CPU-G

Another CPU-G replacement program. It is noticeably behind the previous ones in terms of information volume and 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. What can I say, the program thinks that Ubuntu still works 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 with the installation a little. First install the necessary dependencies:

$ 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

It is worth saying that under Linux there is other software for collecting information about the system. For example, the KDE shell has its own tool, but its databases have not been updated for many years. And Sysinfo is no longer being developed and is not part of the repositories of current versions of distributions.

There are not so many alternatives to CPU-Z for displaying information about the hardware of a computer, even for Windows. For Linux, there are currently only two current utilities left: CPU-X and HardInfo.
