12/12/2023 0 Comments Quick cpu setup![]() Instantaneous values can show the minimum and maximum CPU frequency values, which are quite useful for CPU performance tuning. The kernel support can be enabled/disabled using the /sys/devices/system/cpu/cpufreq/boost file.Ĭpupower application measures average CPU frequency over specified time intervals (1 second by default).Īverage values differ from current instantaneous values from /proc/cpuinfo. You can disable the Turbo Boost using the BIOS or some Linux options/commands. Here, the CPU will be at the nominal/minimal value (1.20Ghz) all the time. Note the difference when you run the same command with Turbo Boost disabled: In the boost state support section, the values for Supported and Active are no. You may find the technical information of these frequencies at the Intel website. Note that the information states the hardware limits ( 1.20 GHz - 3.47 GHz), the possible frequencies ( 3.47 GHz, 3.33 GHz, 2.53 GHz, 1.87 GHz, 1.20 GHz) and the current frequency ( 1.87 GHz). $ cpupower frequency-infoĬPUs which run at the same hardware frequency: 0ĬPUs which need to have their frequency coordinated by software: 0Īvailable frequency steps: 3.47 GHz, 3.33 GHz, 2.53 GHz, 1.87 GHz, 1.20 GHzĪvailable cpufreq governors: conservative, ondemand, userspace, powersave, performanceĬurrent policy: frequency should be within 1.20 GHz and 3.47 GHz. For instance, for an old Intel Core i5-660 with Turbo Boost enabled, you will get the following. To determine if the Turbo Boost is activated and which is the current frequency, you can use cpupower frequency-info.
