Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 35x/34x/34x/33x Max Frequency without considering Turbo 3098.97 MHz (99.97 x ) TURBO ENABLED on 4 Cores, Hyper Threading OFF True Frequency (without accounting Turbo) 2999 MHzĬPU Multiplier 30x || Bus clock frequency (BCLK) 99.97 MHz

Linux's inbuilt cpu_khz code emulated now To guess correctly try estimating via tsc It would output information like this: Cpu speed from cpuinfo 2999.00MhzĬpuinfo might be wrong if cpufreq is enabled. Install it with apt and run with sudo $ sudo apt-get install i7z sudo i7z This can be useful for advanced level diagnostics or like when you are trying to overclock your cpu. It shows a bunch of info about the individual cpu cores including clock frequency, temperature and voltage. There is a command line utility called i7z that works for intel core i3/i5/i7 cpus. It will show summary and graph of various cpu parameters. In order to monitor the power consumption, it must be run with root privileges. The next tool is s-tui and it monitors all parameters including usage, temperature, frequency and power usage and plots multiple graphs in Use the Ctrl-B + ' and Ctrl-B + % option to create horizontal and vertical dividers to get 4 equal sized child terminals and then run one turbostat command in each of the child terminal.

If you want to view all graphs together in 1 terminal screen then use the tmux program. $ sudo turbostat -Summary -quiet -show Avg_MHz -interval 1 | gawk '' | ttyplot -s 100 -t 'Turbostat - CPU Power (watts)' -u 'watts' The cpu clock speed is the frequency and is measured in Mhz or Ghz. With multi-tab terminals like Konsole you can view each graph in its own tab. The turbostat command can be combined with ttyplot to generate nice terminal graphs. The TSC_MHz field seems to indicate the base clock frequency of the processor. The Bzy_Mhz measures the frequency of those cycles when the cpu is under load. The Avg_MHz fluctuates in real-time as per the load on the cpu. There are 3 different columns for frequency: Avg_MHz, Bzy_MHz, TSC_MHz. Turbostat $ sudo turbostat -Summary -quiet -show Busy%,Avg_MHz,PkgTmp,PkgWatt -interval 1 $ sudo turbostat -Summary -quiet -show Busy%,Avg_MHz,Bzy_MHz,TSC_MHz,PkgTmp,PkgWatt -interval 1Īvg_MHz Busy% Bzy_MHz TSC_MHz PkgTmp PkgWatt If you just want to see the cpu usage, you can use the System Monitor which is available on both gnome and kde desktops.įor more details like the clock frequency, temperature etc, use the commands shown below. There are quite a few commands on linux for monitoring cpu metrics.
