The kernel 3.13 series regulates the CPU frequency dynamically.

CPU frequency scaling enables the operating system to scale the CPU frequency up or down in order to save power. CPU frequencies can be scaled automatically depending on the system load, in response to ACPI events, or manually by userspace programs.

CPU frequency scaling is implemented in Linux kernel, the infrastructure is called cpufreq.

You can set the CPU frequency with the applet indicator-cpufreq for the panel.

Sometimes, the automatic kernel CPU frequency regulator doesn't work exactly. For example SuperTuxKart. This game needs much CPU power but the kernel regulates the CPU frequency not to often to the highest rate. Thus the frame rate drops in STK.
