The governor "ondemand" may decide which speed to useĬpufreq stats: 3.00 GHz:10.45%, 2.30 GHz:0.29%, 1.80 GHz:1.72%, 800 MHz:87.55% (28605)įor more information on how to check and set your CPU stepping from the command line I have created an answer to another question that explains how to do so here, have a look. It returns something like cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009ĬPUs which run at the same hardware frequency: 0ĬPUs which need to have their frequency coordinated by software: 0Īvailable frequency steps: 3.00 GHz, 2.30 GHz, 1.80 GHz, 800 MHzĪvailable cpufreq governors: conservative, ondemand, userspace, powersave, performanceĬurrent policy: frequency should be within 800 MHz and 3.00 GHz. Normally those are set to On Demmand by default which means your CPU's frequency will be lowered when not under intensive usage.Ĭpufreq-info is an utility to check the steps available from your CPU, which kernel governor is in use currently per core of your CPU and much more information about your CPU capabilities. Linux uses governors to set which stepping your CPU will operate (if your CPU supports stepping settings). Here are two webpages which could be of interest: Is the correct one? Is the 2.13 GHz a refer to the sum of the frequencies of the cores?įinally, which of these frequency tells me about the cycles per second / clock ticks per second taken by my system clock?ĮDIT: In a small extension to Bruno Pereira's nice answer, I found that making a processor operate at different frequencies on the fly is also dynamic frequency scaling or cpu throttling. The processor frequency here is 2.13 GHz on the first line and 933 Mhz on the second. What I don't get are the lines marked: model name : Intel(R) Core(TM) i3 CPU M 330 2.13GHz 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 Here is the end of the output of the command cat /proc/cpuinfo: processor : 3 ![]() ![]() I tried sysctl machdep.cpu, but it didn't retrieve CPU core ID.I was looking at my processor SPECS on my Ubuntu Linux 11.10 system. ![]() Model name : Intel(R) Core(TM) i5-7267U CPU 3.10GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc rep_good xtopology nonstop_tsc unfair_spinlock eagerfpu pni pclmulqdq ssse3 cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt aes xsave avx rdrand hypervisor lahf_lm abm 3dnowprefetch invpcid_single pti retpoline fsgsbase avx2 invpcid rdseed flush_l1dĪddress sizes : 39 bits physical, 48 bits virtualĭoes macOS/OS X have a command to retrieve detailed CPU and CPU cores information equal to Linux /proc/cpuinfo? I really want to know a CLI command to retrieve the Mac's CPU core ID. Using this command, users can get CPU and CPU's core information like below. Linux has a command to retrieve detailed CPU information using cat /proc/cpuinfo.
