cat /proc/cpuinfo
ではTurbo boost時など、実クロックがわからない。
/sys/devices/system/cpu?/
以下から読むこともできるが面倒である。
apt-get install -y i7z i7z_GUI
使い方
sudo i7z
Cpu speed from cpuinfo 3092.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating via tsc
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 3092 MHz
CPU Multiplier 31x || Bus clock frequency (BCLK) 99.74 MHz
Socket [0] - [physical cores=2, logical cores=4, max online cores ever=2]
TURBO DISABLED on 2 Cores, Hyper Threading ON
Max Frequency without considering Turbo 3092.00 MHz (99.74 x [31])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 31x/31x/31x/31x
Real Current Frequency 2066.39 MHz [99.74 x 20.72] (Max of below)
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 % Temp VCore
Core 1 [0]: 1976.06 (19.81x) 3.29 35.3 1 61.6 37 1.0208
Core 2 [1]: 2066.39 (20.72x) 21.1 60.6 1 24.3 40 1.0208
C0 = Processor running without halting
C1 = Processor running with halts (States >C0 are power saver modes with cores idling)
C3 = Cores running with PLL turned off and core cache turned off
C6, C7 = Everything in C3 + core state saved to last level cache, C7 is deeper than C6
Above values in table are in percentage over the last 1 sec
[core-id] refers to core-id number in /proc/cpuinfo
