So if you have an Core 2 Duo, AMD Bulldozer, Core i7, etc. This will give you the individual MHz for each CPU Core. CPU MHz: 1600.000 cat /proc/cpuinfo or more precise cat /proc/cpuinfo grep 'MHz'. There is also a field inside the information of each processor field which says cou cores are 2. This will give you the general MHz for the CPU. If commands like lscpu, dmidecode can show you the amount of CPUs, Cores and threads/siblings for each, then the issue is with how cpuinfo handles the information. The output of lscpu piped through grep is much more succinct. The lscpu command fetches the CPU architecture information from the sysfs and /proc/cpuinfo files and displays it in a terminal. The output of the above command should give you more in-depth detail about your CPU, including the slot type, size, capacity, width, clock speed, vendor and ID. The command-line utility lscpu in Linux is used to get CPU information of the system. Now it says that there are 4 processors on the system. This might be do to how cpuinfo shows this for AMD or that specific family model. To get detailed, in-depth information on the CPU class, use sudo privileges with the lshw command: sudo lshw -C CPU. ![]() Model name : Intel(R) Core(TM) i3 CPU M 330 2.13GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx rdtscp lm constant_tsc arch_perfmon pebs bts xtopology nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm arat dts tpr_shadow vnmi flexpriority ept vpidĪddress sizes : 36 bits physical, 48 bits virtual On my laptop, I get the following output: How does one interpret the information printed out by the following command in Linux A guide on how to use the /proc file systems in Linux for CPU information to list available files and display the contents of a specific file in the. cpuinfo is a library to detect essential for performance optimization information about host CPU.
