Monitoring Processor Energy Usage with Intel® Power Gadget 2.0
Intel® Power Gadget 2.0 is a software-based power estimation tool enabled for 2nd Generation Intel® Core™ processors. It includes a Microsoft Windows* sidebar gadget, driver, and libraries to monitor and estimate real-time processor package power information in watts using the energy counters in the processor. With this release, we are providing functionality to evaluate power information on various platforms including desktops/notebooks and servers.
Traditional methods to estimate power/energy usage of the processor has always been a cumbersome task that included special purpose tools or instrumentation on the motherboard along with third party equipment. Intel had earlier released Intel® Power Gadget 1.0 that included estimation of processor power via energy counters available in 2nd Generation Intel® CoreTM processor family. The motivation for the gadget was to assist end-users, ISV's, OEM's, developers, etc in more precise estimation of power from a software level without any H/W instrumentation.
With the current release, we are providing additional functionalities that include estimation of power on multi-socket systems as well as externally callable APIs to extract power information within sections of code. The multi-socket support essentially evaluates the Energy MSR ...
