• cpupower frequency-info shows lower cpu frequency in hardware limits section.
• How to run CPU with maximum speed with turbo power

# cpupower frequency-info

analyzing CPU 0:
  driver: pcc-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  hardware limits: 1.20 GHz - 2.60 GHz              <<<<---------[ Less than Maximum CPU speed ]
  available cpufreq governors: conservative, userspace, powersave, ondemand, performance
  current policy: frequency should be within 1.20 GHz and 2.60 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 2.50 GHz (asserted by call to hardware).
