Cpu speed from cpuinfo 3491.00Mhz
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) 3491 MHz
  CPU Multiplier 35x || Bus clock frequency (BCLK) 99.74 MHz
 
Socket [0] - [physical cores=4, logical cores=8, max online cores ever=4]
  TURBO ENABLED on 4 Cores, Hyper Threading ON
  True Frequency 3590.74 MHz (99.74 x [36])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is  39x/39x/38x/37x
  Current Frequency 798.30 MHz [99.74 x 8.00] (Max of below)
        Core [core-id]  :Actual Freq (Mult.)      C0%   Halt(C1)%  C3 %   C6 %  Temp
        Core 1 [0]:       798.30 (8.00x)           1      99       1       0    24

C0 = Processor running without halting
C1 = Processor running with halts (States >C0 are power saver)
C3 = Cores running with PLL turned off and core cache turned off
C6 = Everything in C3 + core state saved to last level cache
  Above values in table are in percentage over the last 1 sec
[core-id] refers to core-id number in /proc/cpuinfo
