Cpu speed from cpuinfo 3686.00Mhz
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) 3686 MHz
  CPU Multiplier 37x || Bus clock frequency (BCLK) 99.62 MHz

Socket [0] - [physical cores=16, logical cores=16, max online cores ever=16]
  TURBO ENABLED on 16 Cores, Hyper Threading OFF
  Max Frequency without considering Turbo 3785.62 MHz (99.62 x [38])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4/5/6 Cores is  54x/54x/51x/51x/51x/51x
  Real Current Frequency 4577.10 MHz [99.62 x 45.94] (Max of below)
