Originally Answered: How do I know whether my Mac OS X is Intel or PowerPC? Apple hasn't made a PowerPC-based desktop computer since 2005. Their last PowerPC-based laptop was made in 2006. So if your computer is newer than that, it is Intel-based.
Intel® Atom™ processors are not supported. It is supported on Windows. and macOS. 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.

Hi i was usinig mac osx 10.10.5 and intel compiler fortran 2015 and everything worked just fine, after updating to mac osx 10.11 when i use ifort in terminal it says ' command not found ' but gfortran 5.1 works fine.

Introduction

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). Intel® Atom™ processors are not supported. It is supported on Windows* and macOS* 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 FilesIntelPower 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*)**

macOS* 10.11 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*)**

Run the msi package as an administrator. Accept the UAC, if one appears
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)

**Installation / Setup (macOS*)**

Double click the downloaded DMG (Intel Power Gadget.dmg)
Double click the package (Install Intel Power Gadget.pkg)
Follow the installer prompt instructions to complete installation

On recent macOS versions, after installation users need to explicitly allow the Power Gadget driver to load:

Open System Preferences, and click on 'Security and Privacy'
Click the lock at the bottom of the page to unlock changes
Click 'Allow' to allow system software from Intel Corporation:
Restart your computer to apply the changes

On macOS Catalina (10.15), users may need to perform additional steps to enable the Power Gadget driver to automatically load (this is due to a bug in macOS).

Open the Terminal application
Enter the following command, and press Enter (requires a password to complete):
Restart your computer to apply the changes

**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:

Start a command a log power data to logfile until the command finish:

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

Mac Os For Intel I5 Processor

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