Introduction

Intel® Power Gadget is a software-based power usage monitoring tool enabled for Intel® Core™ processors (from 2nd Generation up to 6th Generation Intel® Core™ processors), Intel® Atom™ processors 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

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 8* (desktop mode).

Brief Description (Windows version)

Intel® Power Gadget 3.0 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 3.0 for 64-bit OS). A command line version of the tool (PowerLog3.0.exe) is also included

.

  • Let you log the power and frequency measurements and save it in a csv format.

    Steps

    API

    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. For more information on the API's, see:

      • 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;

I wonder how the power gadget makes power measurements. Under what conditions can measurements be considered accurate? Where can I find documentation?

Has anyone tried to use power gadget in a VMware VM running Windows 2012R2?

The application starts up and shows the graphs, however it reports a package frequency of 0.00 GHz. I've enabled the CPU Performance Monitoring Counters on the VM (https://kb.vmware.com/kb/2030221) but still no information.

VM runs on Intel Xeon e5-2630 v4.

Here is what I saw on my Windows.RS1.

"A digital signed driver is required"

Also, using the same i7 5820k CPU and MSI X99A Raider motherboard, if I change the base CPU clock in the BIOS to anything other than 100 MHz, then the Power Gadget reports power usage as < 1W all the time, even under load. I know this to be wrong.

I normally use the second XMP profile for my Corsair RAM which is DDR4-2800 , and that profiles requires a base CPU clock of 127 MHz. The power usage gets reported as <1W in other programs too, not just the power gadget.

Again, is this a BIOS issue that I should pursue with MSI ? Or is there another problem ?

I have an i7-5820k.

The power gadget version 3.07 under Windows Pro x10 reports a power limit of 4095W .

Surely this is not correct.

Is it a bug in the Power Gadget ? Or another issue, maybe a BIOS bug ?

FYI, I'm using an MSI X99A Raider, MX-7885, with latest BIOS revision P.5 .

Any help^would be appreciated.

I'm trying to run this on an Intel Edison and I'm getting the following error:

 

# ./power_gadget -e 1000 -d 10
RAPL not supported, or machine model 406a8 not recognized.
Init failed!

Hi

Looks like a great tool.  I installed the linux version but I got an error when I run the tool.

 Init failed!

I am running on core i7 processor.

how to change bios that fix error?

I would appreciate any help,thanks.

Power gadget doesn't work on Microsoft Surface book running Windows 10 14295 build. For example Package Pwr0: is reporting "1.#JW" watts, package temp 0 reports "196C". Must be something to do with the Skylark chip and latest windows 10 builds. Can someone debug/update the tool?

A note about Power Gadget (PG) for Linux ver 2.5. On my E5-1650 v2 (an Ivy Bridge) PG is causing multiple Fixup Exceptions due to the fact that is trying to access Power Plan 1 data via MSR. This is not an error in general but can speed down measurements.

Please permanently fix link(s) to point to newest downloads. For example, as of 2016-02-08, link above for mac-os-x zip is dated 2014-01-17, but newer 3.0.1 dated 2015-11-11 is available here: https://software.intel.com/sites/default/files/managed/59/39/IntelPowerGadgetMac3.0.1.zip

It would also help if the dmg and pkg files had the full version number and/or release-date in their filename: that is "Install Intel Power Gadget-3.0.1-2014-11-11.pkg" instead of just "Install Intel Power Gadget.pkg"

Someone at homebrew knew how to find it... I tried a 3.0.2 and 3.0.3 and 3.0.4 but all are 404.

homebrew cask install intel-power-gadget
cask 'intel-power-gadget' do
  version '3.0.1'
  sha256 '538a792721604e2155b3a48caa4084db751a91b170e5fa62bf0331d3147f2239'

  url "https://software.intel.com/sites/default/files/managed/59/39/IntelPowerGadgetMac#{version}.zip"
  name 'Intel Power Gadget'
  homepage 'https://software.intel.com/en-us/articles/intel-power-gadget-20'
  license :gratis

  # this bogus-looking character accurately reflects an upstream error
  container nested: 'IntelÆ Power Gadget.dmg'

  pkg 'Install Intel Power Gadget.pkg'

  uninstall pkgutil: 'com.intel.pkg.PowerGadget.*'
end
