$ 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

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.
This is for powernow:
