CPU-X is a Free software that gathers information on CPU, motherboard and more.
CPU-X is a system profiling and monitoring application (similar to CPU-Z for Windows), but CPU-X is a Free and Open Source software designed for GNU/Linux and FreeBSD.
This software is written in C++ and built with CMake tool.
It can be used in graphical mode by using GTK or in text-based mode by using NCurses. A dump mode is present from command line.

[!CAUTION] This project is not maintained anymore by the lead developer, read this announcement for more details.

Dependencies

Operating systems

CPU-X supports:

• GNU/Linux
• FreeBSD

[!NOTE] Other operating systems are not officially supported by CPU-X, some features are not available.

CPU architectures

CPU-X runs on:

• x86:
  • 32-bit CPUs (IA-32, also known as i386, i486, i586 and i686)
  • 64-bit CPUs (x86_64, also known as x64, AMD64, and Intel 64)
• ARM (since v5.1.0):
  • 32-bit CPUs (ARM32, also known as AArch32)
  • 64-bit CPUs (ARM64, also known as AArch64)

[!NOTE] Other CPU architectures are not supported by CPU-X.

Build-only dependencies

These dependencies are needed to build CPU-X:

• A C++ compiler (GCC or Clang)
• CMake (version 3.12 or newer is needed)
• Pkg-Config / Pkgconf
• NASM (for x86 CPUs only)

Test dependencies

These dependencies are optional to test CPU-X:

• Grep
• GNU Awk¹
• Mawk¹
• One true awk¹

¹At least on Awk is required, e.g. the default Awk on the system.

Build and run dependencies

These dependencies are needed to build² and run CPU-X:

• Gtkmm3 (versions 3.12 to 3.24 are supported)
• NCurses
• Libcpuid (version 0.8.0 or newer is needed)
• Pciutils
• EGL (version 1.5 or newer is needed), with OpenGL
• Vulkan
• OpenCL (version 1.2 or newer is needed)
• Procps-ng (Linux) / Libstatgrab (*BSD)

²On some GNU/Linux distributions, the appropriate -dev or -devel package is needed.

All packages:

From GitHub releases

Look for Assets here for portable binary (AppImage).

From Flathub

CPU-X is available as Flatpak on Flathub since v5.0.2.

Manual build

For step-by-step guide, please read this page on the Wiki.

Usage

Application is available in menu (System Tools category). If you start the daemon, it will allow CPU-X to access some special devices, which provides more information and avoid empty labels.
The CPU-X daemon requires root privileges, and uses Polkit for privileges escalation.

You can use cpu-x from command line, some options are available, like:

• --gtk: to start the graphical user interface (default)
• --ncurses: to start the text-based user interface
• --dump: to get a summary of data

Use --help to see all arguments.

Wiki
