Yes, all you have to do is:
first, set tlp "governer" to performance for both ac and batt in your /etc/default/tlp file and while you are there, go ahead and enable turbo boost as well
then, edit /etc/default/grub and insert
like this example
GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable quiet splash"
execute this command to apply the change to grub
then, install indicator-cpufreq
sudo apt-get update
sudo apt-get install indicator-cpufreq
reboot for your changes to take effect.
After you reboot, you will see an icon on your unity panel, click on this icon and you can set the cpu to performance (full), ondemand (only when needed), powersave, or conservative.
Disabling pstate may not be necessary, you can try it on and off to see if there is a difference. Make sure to update grub after making that change.
Also, indicator-cpufreq will not allow changes with pstate on (only with pstate disabled), you will still have to do that manually.
Finally, you can get better numbers from i7z:
sudo apt-get install i7z
and then, run
Install lm-sensors and run sensors detect:
sudo apt-get install lm-sensors
Follow the prompts and select yes to everything.
finally, these links may help:
Not only does this allow hardware acceleration for flash but installs VDPAU and i965
and these more recent benchmarks show a slight advantage from disabling pstate and using performance
