This is for powernow:

$ cpupower frequency-info
analyzing CPU 0:
  driver: powernow-k8
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 8.0 us.
  hardware limits: 800 MHz - 2.70 GHz
  available frequency steps: 2.70 GHz, 2.00 GHz, 1.40 GHz, 800 MHz
  available cpufreq governors: conservative, ondemand, userspace, powersave, performance
  current policy: frequency should be within 800 MHz and 2.70 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz.
  cpufreq stats: 2.70 GHz:1,00%, 2.00 GHz:0,01%, 1.40 GHz:0,01%, 800 MHz:98,98% (822)
  boost state support:
    Supported: yes
    Active: yes

and this is for acpi-cpufreq:
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0 1
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 4.0 us.
  hardware limits: 1.40 GHz - 2.70 GHz
  available frequency steps: 2.70 GHz, 2.40 GHz, 2.00 GHz, 1.70 GHz, 1.40 GHz
  available cpufreq governors: conservative, userspace, powersave, ondemand, performance
  current policy: frequency should be within 1.40 GHz and 2.70 GHz.
                 The governor "ondemand" may decide which speed to use
                 within this range.
  current CPU frequency is 2.70 GHz (asserted by call to hardware).
  boost state support:
    Supported: yes
    Active: yes
    Boost States: 2
    Total States: 8
    Pstate-Pb0: 3200MHz (boost state)
    Pstate-Pb1: 2900MHz (boost state)
    Pstate-P0: 2700MHz
    Pstate-P1: 2400MHz
    Pstate-P2: 2000MHz
    Pstate-P3: 1700MHz
    Pstate-P4: 1400MHz
    Pstate-P5: 900MHz

In case of powernow-k8, "cpupower monitor" is not working properly:
$ sudo cpupower monitor
    |Mperf || Idle_Stats
CPU | C0 | Cx | Freq || POLL | C1 | C2
   0|******|******|******|| 0,00| 0,00| 56,89
   1|******|******|******|| 0,00| 0,00| 58,31
   2|******|******|******|| 0,00| 0,00| 32,91
   3|******|******|******|| 0,00| 0,00| 99,90
   4|******|******|******|| 0,00| 0,00| 94,74
   5|******|******|******|| 0,00| 0,01| 100,1

so i can't say exactly whether powernow applies TurboCore frequencies.
