Here, the loading of the driver takes place. This library must be initialized at the start of the program by calling IntelEnergyLibInitialize(). 3.2 OverviewĪs the primary API, developers may use Intel® Power Gadget’s EnergyLib32.dll for 32-bit applications or EnergyLib64.dll for 64-bit applications. Although the Intel® Power Gadget API can be used with a sampling frequency ranging from 1 to 1000 milliseconds, the optimal sampling frequency of 100 milliseconds is the default selection on the GUI and is recommended for application developers. Higher the frequency, greater will be the accuracy of the data but poorer will be the performance of the system. Data is acquired from specific MSRs at a fixed sampling frequency.

Sample code called “” to use Intel® Power Gadget’s DLL is available for download at the bottom of this page 3.API of Intel® Power Gadget 3.1 Concept of Samplingįor a good understanding of the API, it is essential to be familiar with the concept of sampling.

The installer sets two environment variables on installation: Microsoft Visual C++ 2010 SP1 Redistributable Package will also automatically get installed if not yet installed.įor more information on system requirements and installation, please visit Intel® Power Gadget page 2.Developers’ Tools Net Framework 4 will automatically be downloaded from the Microsoft website if not yet installed in your system. Follow the installer prompt instructions to complete installation.Download the appropriate Intel® Power Gadget installation package on your system.For more details on the API, please refer to subsequent sections. The DLL serves as a C++ Application Programming Interface (API). This data can be viewed on a Graphical User Interface (GUI) and/or logged for a required duration of time.ĭevelopers may use this data to create their own application by exploiting the Dynamic-Link Library (DLL) used by the Intel® Power Gadget. The supported MSRs are correlated with three MSR functions as described in Table 1. The PROCHOT feature is available only in 3rd Generation Intel® Core™ processors or later.

The data is obtained from the Model Specific Registers (MSRs) and energy counters that are available only in 2nd Generation Intel® Core™ or later processors.

Intel® Power Gadget for Windows is an application which presents real-time data about a 2 nd generation or later Intel® Core processor regarding current estimated processor power, package power limit, current processor frequency, base frequency, GT frequency, current temperature, maximum temperature, proc hot (when package temperature exceeds max temperature) timestamps and elapsed time. You can also click Start Log to log all activity.Authors: Seung-Woo Kim, Joseph Jin-Sung Lee, Vardhan Dugar, Jun De Vega 1.Introduction 1.1 About Intel® Power Gadget for Windows Right-clicking on the app gives you the option to run at startup, always on top or close. A command-line version of the tool is also included. Set of driver and libraries which access and post-process the processor energy counter to calculate the power usage in Watts, temperate in Celsius, and frequency in GHz. Intel Power Gadget consists of the following components.

The motivation for the tool was to assist end-users, ISV’s, OEM’s, developers, and others interested in a more precise estimation of power from a software level without any H/W instrumentation. Traditional methods to estimate power/energy usage of the processor have always been cumbersome tasks that included special-purpose tools or instrumentation on the platform and third-party equipment. Intel Power Gadget is a software-based power usage monitoring tool enabled for Intel Core processors (from 2nd Generation up to 10th Generation Intel Core processors).
