Introduction: What is Intel® Power Gadget?
Simply speaking, Intel® Power Gadget is a software-based power usage monitoring tool for Intel® Core™ processors from 2nd generation Intel® Core™ processors up to the 7th generation Intel® Core™ processors (Intel® Atom™ processors are not supported).
This power usage monitoring software is supported on both Windows and Mac OS X. It also includes the application, driver, and libraries to return estimated real-time processor package information in watts with the help of the processor’s energy counters.
This new release provides the functionality to evaluate power information on various platforms including notebooks, desktops, and even servers.
Note: According to Intel, “Windows 7 and 32-bit versions of the Intel® Power Gadget for Windows have ceased development from version 3.0.7. Starting with version 3.5 and going forward, only the 64-bit version and Windows 8 will be supported”.
Background: What’s it for?
The main purpose of the software is to assist end-users, ISV’s (independent software vendors), and OEM’s (original equipment manufacturers) who are interested in having a precise estimation about how much power from a software level without any errors.
New features: What’s new?
In version 3.0, new features were added that include estimation of power on multi-socket systems and externally callable APIs to return accurate power information by sifting through sections of code.
The multi-socket support evaluates the Energy MSR on a per-socket basis and returns an estimated power draw per socket.
The API layer is basically a set of libraries and DLLs that has the flexibility to build the tool from code sections of an application. And in this version, this now includes support for Windows 10.
Intel® Power Gadget also provides a C/C++ Application Programming Interface (API) for accessing this power and frequency data in your program; the API is supported on Windows and Mac OS X. See the following to learn more:

Intel® Power Gadget version 3.5 is composed of components, drivers, and libraries, which access and post-process the processor energy counter to return an accurate power usage in Watts, the temperature in Celsius, as well as the frequency in GHz (as seen in the image below):
