The final item, bogomips, is a Linux-specific measurement of the CPU's speed in MIPS (millions of instructions per second) while not performing any actual work it is not an accurate indicator of overall processor speed and is only used for some testing purposes.Ĭopyright © 2006 The Linux Information Project. The flags field shows which features are available in the CPU this information is of interest only to users with an in-depth knowledge of processors. Among them are processor (the value of which is zero for single-processor systems), vendor_id (the value of which is GenuineIntel in the case of an Intel processor), cpu family, model_name, cpu MHz (processor speed in millions of cycles per second), cache size (the amount of high speed cache memory built into the processor) and fpu (the value of which is yes if the processor contains a floating point unit). Only a few of the lines contain information that is meaningful to most users. Each key word can be any combination of alphanumeric, underscore and space characters. The information about each processor consists of a set of lines (18 on Red Hat 9), each of which contains a key word followed by a separator (consisting of spaces, a colon and then another space) and then by a value. cat /proc/cpuinfo processor : 0 vendorid : GenuineIntel cpu family : 6 model : 45 model name : Intel (R) Xeon (R) CPU E5-2660 0 2.20GHz stepping : 6 microcode. Here is an example output from cat /proc/cpuinfo of a system. If a computer contains two or more CPUs, the information about each is separated by a blank line. The file /proc/cpuinfo displays what type of processor your system is running including the number of CPUs present. processor : 0 vendorid : GenuineIntel cpu family : 6 model : 142 model name : Intel(R) Core(TM) i5-7267U CPU 3.10GHz stepping : 9 cpu MHz : 3096.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0. It can easily be read with a command such as cat, i.e., Linux has a command to retrieve detailed CPU information using cat /proc/cpuinfo.Using this command, users can get CPU and CPU's core information like below. proc/cpuinfo is a short, read-only, plain text file that contains information about the CPUs (central processing units) on a computer. The /proc/cpuinfo file, by The Linux Information Project LINFO
