Excellent System Utilities: CPU-X – system profiler tool

Last Updated on December 24, 2022

In Operation

CPU-X’s interface is a faithful reproduction of CPU-Z.

The utility displays information in a series of information tabs: CPU, Caches, Motherboard, Memory, System, Graphics, Bench, and About.

Let’s take a look at a few of these tabs: CPU, Memory, and Graphics.

CPU-X - CPU tab

In the CPU tab you get information about the system’s processor name and number, code name, specification, family, instructions, as well as information about the clock speed, and cache of the processor. The CPU usage % shows an averaged figure across all the CPUs’s cores.

As you can see from the image, the system running CPU-X sports an elderly Core i5 processor.

You’ll notice there’s a “Start daemon” button at the bottom of the window. This is ever-present on all the tabs. Running the daemon offers full information about the system. You’ll need elevated privileges. But if you haven’t got elevated privileges you can still run the program albeit with some information omitted.

CPU-X - Memory

On the right hand side, there’s a screenshot of the Memory tab.

The image shows that the motherboard offers 4 RAM slots of which 2 are populated. We are told the size of the RAM together with its DRAM frequency. Information is retrieved using the dmidecode utility.

Whereas the CPU tab of CPU-X is a pretty faithful reproduction of the information offered by CPU-Z, this isn’t the case for the Memory tab.

We’re missing lots of information such as the type of RAM, CAS latency, and more.

CPU-X - Graphics

GPUs have sparked an AI boom, become a key part of modern supercomputers and continued to drive advances in gaming and pro graphics.

The Graphics tab is shown in the image to the left. It shows that our system is using a NVIDIA GTX 950 graphics card.

There’s information about the usage of the GPU, together with clock speeds.

The utility also reports in realtime the temperature of the GPU which is retrieved by accessing the nvidia-smi utility.

The software also offers a couple of simple benchmarking tests which you can run on a configurable number of threads.

inxi is much better to be fair for sharing system information with others.

It’s what people usually recommend as far as I’ve seen. I’d have to check out how CPU-X differs before making any claims though.
