Okay. Right away I notice a difference with the program i7z:

Cpu speed from cpuinfo 2875.00Mhz
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) 2895 MHz
  CPU Multiplier 29x || Bus clock frequency (BCLK) 99.83 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 2994.83 MHz (99.83 x [30])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 39x/37x/36x/35x
  Real Current Frequency 2881.62 MHz [99.83 x 28.87] (Max of below)
        Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 % Temp VCore
        Core 1 [0]: 2865.41 (28.70x) 1.77 96.2 1 1 46 1.0009
        Core 2 [1]: 2874.93 (28.80x) 1.74 86.3 1 11 46 0.9927
        Core 3 [2]: 2881.62 (28.87x) 1.34 96.1 1 1.55 46 1.0076
        Core 4 [3]: 2877.37 (28.82x) 1.4 95 1 2.62 46 1.0226

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

WAY MORE activity in C6 state. Although I don't see any listings for C10
