Intel turbo boost technology is a way of increasing the fundamental operating frequency of processor cores. This mechanism allows to increases the processor performance when it running below it’s power, current, and temperature specification limits.
This turbo boost technology implemented with Intel’s Nehalem , Sandy Bridge and Ivy Bridge based CPUs is optimized with Intel 2nd and 3rd generation CPUs and hence this is used on them. The turbo boost technology is enabled or disabled only on demand and it is done by a switch in BIOS, there is no any user controllable option.
The dynamic frequency power sharing method used for graphical intensive applications is works with this technology and the processor core operating frequency may be higher than their maximum rated values. This action will not affect badly because this happens temporary.
Is turbo boosting actually working? And so how we can monitor these things? Yes there is a tool from Intel that can be monitored the actions of cores. This tool can be downloaded from here. This tool works with every CPU that supports the turbo boost technology. You can see the supported CPUs and Operating systems below (Taken from the Intel’s web site)
