Introduction

Intel® Power Gadget is a software-based power usage monitoring tool enabled for Intel® Core™ processors (from 2nd Generation up to 7th Generation Intel® Core™ processors). Intel® Atom™ processors are not supported. It is supported on Windows* and Mac OS X* and includes an application, 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 notebooks, desktops and servers. Windows 7* and 32-bit versions of the Intel® Power Gadget for Windows* has ceased development from 3.0.7. Starting with version 3.5 and going forward, only the 64-bit version and Windows 8* will be supported.

Background

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 platform along with third party equipment. 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.

New Features

In version 3.0 there are additional features 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 on a per-socket basis and provides an estimate of power draw per socket. The API layer is a set of libraries and dlls that can be called and offers the flexibility to build the tool within code sections of an application. Latest release also includes support for Windows 10*.

Brief Description (Windows*)

Intel® Power Gadget 3.5 consists of the following components. 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 (default install directory will be ~\Program Files\Intel\Power Gadget 3.5). A command line version of the tool (PowerLog3.0.exe) is also included

System Requirements (Windows*)

  • Windows 8*
  • Windows 10*
  • Windows Server 2008, Windows Server 2012
  • Microsoft* .Net Framework 4
  • Microsoft Visual C++ 2017 Redistributable package
  • 2nd Generation Intel® Core™ Processor or later, older processors not supported
    • Single socket
    • Multi-socket

System Requirements (MacOS*)

  • Mac OS X* 10.6 or later
  • 2nd Generation Intel® Core™ processor or later

Known Limitations / Issues

  • Graphs will not appear if your processor does not have the appropriate hardware counters
  • Discrete graphics cards are not supported and GPU graphs will not appear unless Intel graphics is in use
  • Windows 7* supported builds are below in the Archive section

Installation / Setup (Windows*)

  1. Run the msi package as an administrator. Accept the UAC, if one appears
  2. Follow the installer prompt instructions to complete installation
    1. .Net Framework 4 (will automatically be downloaded from Microsoft* site if not yet installed in your system) needs Internet connection
    2. Microsoft* Visual C++ 2017 Redistributable Package (will automatically get installed if not yet installed)

Usages (Windows*)

Common use of Intel® Power Gadget is to monitor energy usage of the processor

  • Provides processor power (Watts), temperature (Celsius) and frequency (MHz) in real-time via graph displayed in the GUI
  • Let you log the power and frequency measurements and save it in a csv format.
  • Double click on the desktop shortcut and the GUI will launch
  • Drag to move the GUI.
  • Right click the GUI and a pop-up menu will show up allowing you to choose options or close the application. Options have the following parameters. Click “Start Log” button in the GUI to start logging. Press the same button “Stop Log” to stop logging. While it’s logging, red label “REC” will blink in the power chart area.
  • You can choose to add time-stamp to the log file name or not.
  • You can choose the log file name.
  • You can choose to resize the GUI from 100% to 300% by dragging the slider and testing the new size with the “Apply Size” button and accept the changes by pressing “Ok”.
  • Screen Update Resolution lets you change how often the GUI is updated at runtime. This may range from 50 ms to 1000 ms. (Default set to 1000 ms)
  • Log Sampling Resolution lets you change the logging sampling resolution ranging from 1 ms to 1000 ms. (Default set to 100 ms)
  • In a multi-socket system, you can choose which package information to display in the GUI. The log will record all package information in a csv file.
  • Click "Start Log" button in the GUI to start logging. Press the same button "Stop Log" to stop logging. While it's logging, red label "REC" will blink in the power chart area

Using Intel® Power Gadget 3.0 in a script

In order to start and stop the logging in a script, first launch the GUI as usual.

  • At the beginning of the script, call "IntelPowerGadget.exe -start" and it will trigger the logging in the GUI.
  • At the end of the script, call “IntelPowerGadget.exe -stop” and it will stop the logging.

The parameters for the log are based on the options set in the GUI.

PowerLog3.0

PowerLog3.0.exe is the command line version of Intel® Power Gadget in logging power usage

Usage:

  • Log power data to logfile for a period of time:
PowerLog3.0.exe [-resolution <msec>] –duration <sec> [-verbose] [-file <logfile>]
  • Start a command a log power data to logfile until the command finish:
PowerLog3.0.exe [-resolution <msec>] [-file <logfile>]  [-verbose] –cmd  <command>

Logfile data

Logfile will include the elapsed timed, package power limit, processor frequency, GT frequency, processor temperature, average and cumulative power of the processor

  • Processor Energy (Total energy of the processor) = IA Energy + GT Energy (if applicable) + Others (not measured)
  • IA Energy (Energy of the CPU/processor cores)
  • GT Energy (Energy of the processor graphics) – If applicable , some processors for desktops and servers don’t have it or may have use discrete graphics

Only works on 2nd Generation Intel® Core™ processor family or newer. Atom processors not yet supported.

Use only 32-bit installer for 32-bit OS and 64-bit installer for 64-bit OS

Application may hang after running for a long period of time (just close and restart application)

saw this used in a YT vid today, and thought I'd try and add it to my MacPro6,1 system - still running the original shipping OS for it (10.9.5 .. as all subsequent releases don't allow me access to my Apple pro software - Aperture) / 3.5.5 says it runs on 10.6 or later, but this is false.

System Requirements (MacOS*)
Mac OS X* 10.6 or later

a) please update this page with the correct info, which when I try to run it it fails and I knew it would fail even before trying to run it, as the icon has a line through it / seems to be that 3.5.5 need OSX 10.11 or later

b) there is no older links for MacOS, just Windows / can we have an older link to an older version so I can try it out?

thanks in advance, as I'm sure this would help me delve deeper into my 4-core system and optimize performance in the coming weeks.

hello !

i've installed Intel Power Gadget on a Windows 7 professional SP1 up to date, Intel i3-2350M powered laptop, and the instant after it finished the installation, it gives me a blue screen, and it says there's a problem with a file named "energydriver.sys"

when i reboot my computer, it almost have the time to reach the log-in screen before it re-crash, for the same reason.

how can i fix this ? and if it's a problem of the program, when will it be fixed ?

I installed the Intel® Power Gadget 3.5.0 for Windows on windows 7 64 bit os running intel  i5  3337u laptop cpu.

after installation was over succesfully i faced bsod crash ..

rebooted to uninstall the incompatible application but cant see the app in control panel .so tried uninstalling via program files  installation folder by clicking on gadget uninstaller. but it gives warning that this file is not compatible with the version of the windows u are running. 

in this scenerio how to make full uninstallation completely..

tried third party apps like revo uninstaller bit it doesnt show the app to be uninstalled..

Hello!

For Linux I used before: Intel "Power-Governor": https://software.intel.com/en-us/articles/intel-power-governor

I've quickly checked the code of Power-Gadget and seems to be similar to that of Power-Governor.

Could anybody tell me the difference between both (if any)? or how are these related?

Any hint would be greatly appreciated!

Hello

I have installed IPG 3.5.0 for Windows 10 in my lap core-i5

It works fine, however, No DRAM graph is displayed, nor logged in the csv file

I need DRAM usage. Is it not supported by my core-i5 processor?

Any answer would be appreciated

Thanks

Can we add support for Mac so the stats shows in the Menu Bar, please. Where one can personalize in the apps settings what shows. 

Example: CPU 3.75Gz - 210°F   GPU 54% 

Installed in IceLake machine and doesn't work (nothing happens when running .exe). Works perfectly in older machine types (e.g. SkyLake).

Is it tested on ICL?

 

I can confirm TJ Luoma posting too. Downloaded and installed v. 3.5.4 for Mac but the app displays v. 3.5.3.

 

 

I can confirm TJ Luoma posting. The app and the extension report both CFBundleShortVersionString and CFBundleVersion as 3.5.3.

Also having issues with loading the extension in macOS 10.12.6 for some reason. "/Library/Extensions/EnergyDriver.kext failed to load - (libkern/kext) dependency resolution failure". System Log:

default    02:41:53.024276 -0700    kextd    /Library/Extensions/EnergyDriver.kext - no compatible dependency found for com.apple.kpi.unsupported.
default    02:41:53.024699 -0700    kextd    /Library/Extensions/EnergyDriver.kext - no compatible dependency found for com.apple.kpi.iokit.
default    02:41:53.025083 -0700    kextd    /Library/Extensions/EnergyDriver.kext - no compatible dependency found for com.apple.kpi.mach.
default    02:41:53.025470 -0700    kextd    /Library/Extensions/EnergyDriver.kext - no compatible dependency found for com.apple.kpi.libkern.
default    02:41:53.062537 -0700    kextd    /Library/Extensions/EnergyDriver.kext - no compatible dependency found for com.apple.kpi.unsupported.

Does not show up in System Preferences->Security & Privacy->General for user approval. 

Previous versions have not had this issue.

As of 2018-08-27, the file linked as "Intel® Power Gadget 3.5.4 for Mac" 

links to 'https://software.intel.com/file/770353/download'

which redirects to

https://software.intel.com/sites/default/files/managed/ca/40/Intel%C2%AE%20Power%20Gadget%203.5.4.dmg

But after the installation, "/Applications/Intel Power Gadget/Intel(R) Power Gadget.app" reports itself as:

CFBundleShortVersionString: 3.5.3

CFBundleVersion: 3.5.3

 

So either the DMG is mis-named, or the app didn't get its version number bumped when it was updated?
