Originally developed to set the NUMA scheduling and memeory placement policy of Linux processes, the numactl command can also show information about NUMA topology of the CPU hardware from the command line. This command is useful to identify the processor architecture and NUMA topology of the system. The lstopo command (contained in hwloc package) visualizes the topology of the system which is composed of CPUs, cache, memory and I/O devices. The GTK version lshw-gtk is also available. It can report the total number of cores and enabled cores, but miss out on information such as L1/L2/元 cache configuration. Unlike other tools, lshw requires root privilege because it query DMI information in system BIOS. The lshw command is a comprehensive hardware query tool. The lscpu command summarizes /etc/cpuinfo content in a more user-friendly format, e.g., the number of (online/offline) CPUs, cores, sockets, NUMA nodes. It can also identify processor families (e.g., Intel Core 2, AMD Shanghai). Among them is likwid-topology which shows CPU hardware (thread/cache/NUMA) topology information. Likwid (Like I Knew What I'm Doing) is a collection of command-line tools to measure, configure and display hardware related properties. It shows a quick summary of CPU information including CPU model, cache size, clock speed, and supported CPU capabilities. Inxi is a bash script written to gather system information in a human-friendly format. i7z runs in either ncurses-based console mode or QT based GUI. It can display various per-core information in real time, such as Turbo Boost states, CPU frequencies, CPU power states, temperature measurements, and so on. I7z is a real-time CPU reporting tool dedicated to Intel Core i3, i5 and i7 CPUs. The hardinfo is a GUI-based system information tool which can give you an easy-to-understand summary of your CPU hardware, as well as other hardware components of your system. Reported CPU information includes CPU vendor, version, CPU flags, maximum/current clock speed, (enabled) core count, L1/L2/元 cache configuration, and so on. The dmidecode command collects detailed information about system hardware directly from DMI data of the BIOS. Reported information includes processor type/family, CPU extensions, cache/TLB configuration, power management features, etc. The cpuid command-line utility is a dedicated CPU information tool that displays verbose information about CPU hardware by using CPUID functions.

To check up on CPU #0: $ cpufreq-info -c 0 The command shows the hardware frequency that the CPU currently runs at, as well as the minimum/maximum CPU frequency allowed, CPUfreq policy/statistics, and so on. The cpufreq-info command (which is part of cpufrequtils package) collects and reports CPU frequency information from the kernel/hardware. $ more /proc/cpuinfoīy inspecting this file, you can identify the number of physical processors, the number of cores per CPU, available CPU flags, and a number of other things. This virtual file shows the configuration of available CPU hardware. The simpliest method is to check /proc/cpuinfo. In Linux, there are many command line or GUI-based tools that are used to show detailed information about your CPU hardware. What are the available methods to check CPU information on Linux?ĭepending on your need, there are various pieces of information you may need to know about the CPU processor(s) of your computer, such as CPU vendor name, model name, clock speed, number of sockets/cores, L1/L2/元 cache configuration, available processor capabilities (e.g., hardware virtualization, AES, MMX, SSE), and so on. Question: I would like to know detailed information about the CPU processor of my computer.
