I run i7z(/usr/ports/sysutils/i7z), i7z show "real current Frequency" is
3xxx MHz normally without powerd.
i7z can show "real current Frequency" is 18xx MHz with powerd before hang.
Cpu speed from cpuinfo 2594.00Mhz
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) 2593 MHz
CPU Multiplier 26x || Bus clock frequency (BCLK) 99.73 MHz
Socket [0] - [physical cores=4, logical cores=8, max online cores ever=4]
TURBO ENABLED on 4 Cores, Hyper Threading ON
Max Frequency without considering Turbo 2692.73 MHz (99.73 x [27])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 38x/37x/36x/36x
Real Current Frequency 3513.20 MHz [99.73 x 35.23] (Max of below)
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 %
C6 % Temp
Core 1 [0]: 3502.26 (35.12x) 9.87 86.7 0
0 65
Core 2 [1]: 3513.20 (35.23x) 10.1 86.4 0
0 65
Core 3 [2]: 3500.84 (35.10x) 9.91 86.6 0
0 64
Core 4 [3]: 3510.82 (35.20x) 9.8 86.7 0
