![]() ![]() We can change the period by modifying the value after the -n option. rootcent74 cat /proc/cpuinfo processor : 0 vendorid : GenuineIntel cpu family : 6 model : 63 model name : Intel(R) Xeon(R) CPU E5-2640 v3 2.60GHz stepping : 2 microcode : 0x41 cpu MHz : 1200.062 cache size : 20480 KB physical id : 0 siblings : 16 core id : 0 cpu cores : 8 apicid : 0 initial apicid : 0 fpu : yes fpuexception : yes. The above output will refresh every second. Model name : Intel(R) Core(TM) i7-7500U CPU 2.70GHz If we want to monitor the speed for some period of time, we can use the watch command: $ watch -n1 "grep Hz /proc/cpuinfo"Įvery 1.0s: grep Hz /proc/cpuinfo baeldung: Sun Jun 26 16:21:32 2022 From the preceding output, we can see /proc/cpuinfo file contains lots of information such as vendorid, model name, cache size, the CPU rate in MHZ, and so on. ![]() When queried, it provides lots of information about the processor on your Ubuntu Computer. In this example, the clock rates are the same for both cores. The Ubuntu kernel keeps information about your CPU in the /proc/cpuinfo file. cat /proc/cpuinfo on a kernel build from the same commit of rpi-5.10.y for 64-bit is here. So, it means that there are two cores in this particular system that gives the above output. cat /proc/cpuinfo on a kernel build from the same commit of rpi-5.10.y for 32-bit is here. For example, if you have 8 core processor you will see a list of all cores starting from 0 to 7. To get the first processor name using this module: > import cpuinfo > 0'model name' 'Intel(R) Pentium(R) 4 CPU 3.60GHz' If its got more than one processor, then the elements of will have their names. For Windows it looks like it uses the registry. The command will print each logical CPU with an identifying number. For linux it looks in /proc/cpuinfo and tries using uname. In this case, these values are 2.70 GHz and 2904.004 MHz, respectively.įurthermore, the reason there are two outputs is that this file displays CPU information for each processor core. Open your terminal and use less or cat to display the contents of /proc/cpuinfo: less /proc/cpuinfo. Model name : Intel(R) Core(TM) i7-7500U CPU 2.70GHzĪs we mentioned previously, there are base and real-time clock speeds.
