I needed a tool for monitoring the CPU frequencies while testing thermald + intel_pstate, and stumbled upon i7z, so I though I'd share it with you, in case you're not familiar with it.
i7z is a tool that reports Intel Core i7, i5 and i3 CPU information about Turbo Boost, per core CPU frequencies, multipliers, temperature as well as times spent in the C0/C1/C3/C6/C7 states, all in real time.
The tool comes with both console (ncurses) and GUI (Qt) versions, however the GUI doesn't have all the features available in the console version and further more, the GUI incorrectly adds C7 state values to the C0 state for Sandybridge and Ivybridge, so it reports things incorrectly. The console version is recommended.
For more information on i7z, see its Google Code page.
Install i7z in Ubuntu
Ubuntu 13.10 and 14.04 users can install i7z from the official Ubuntu repositories. To install it, use the following command:
sudo apt-get install i7zOr, to install the i7z Qt GUI, use:
sudo apt-get install i7z-guiFor older Ubuntu versions, you can try to use the Ubuntu 13.10 deb files which you can download from here: 32bit | 64bit (the debs can be found under "Built files" at the bottom). Note that I tested this in VirtualBox and the packages install successfully in older Ubuntu versions, but I don't know if i7z actually works since it doesn't work properly in VirtualBox.
Then, start i7z using the following command:
sudo i7zOr, to run the i7z GUI (not recommended for the reasons stated above), use the following command (there's no desktop file so you won't find it in the menu / Dash):
gksu i7z_GUIFor other Linux distributions, search for i7z in the repositories or grab the source from Google Code.
