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). The instantaneous processor frequency can change significantly from moment to moment. Intel reserves these for future definition and shall have no responsibility whatsoever for conflicts or incompatibilities arising from future changes to them. Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. We appreciate all feedback, but cannot reply or give product support. Logging can be enabled at any time by calling StartLog, and subsequently disabled by calling StopLog. less than 20 milliseconds) may result in significant overhead, and may also increase the power consumption of the system, both of which may reduce the usefulness of the data. 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).

If you encounter this situation, temporarily disconnect your device from the Internet after downloading the desired driver, and don't reconnect until you have finished installing the driver. Contact your local Intel sales office or your distributor to obtain the latest specifications and before placing your product order. Intel® Power Gadget also provides a C Application Programming Interface (API) for accessing this power and frequency data in your program. Returns the number of supported MSRs for bulk reading and logging. All products, platforms, dates, and figures specified are preliminary based on current expectations, and are subject to change without notice. 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. Frequency data may be more meaningful if you sample often and average the frequency samples over time. However, note that specifying an invalid MSR address can crash your system and could potentially corrupt it. This application is implemented as a desktop gadget, consisting of a set of blocks and located on top of all windows. If the Graphics Control Panel still shows as installed in your system after uninstalling drivers, see, To download the latest graphics driver available for your device, visit our. Don’t have an Intel account? for a basic account. Reads sample data from the driver for all the supported MSRs. Forgot your Intel Try these quick links to visit popular site sections. The information here is subject to change without notice. Returns the number of CPU packages on the system. The log will record all package information in a csv file. Don’t have an Intel account? Returns the system time as of the last call to ReadSample. Returns in szName the name of the MSR specified by iMsr. The frequency at which you read samples may have an impact on the accuracy of data. If your computer is connected to the Internet, the Windows Update tool may attempt to automatically install the latest drivers. A previous driver had better functionality for your specific needs. 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. Right click the GUI and a pop-up menu will show up allowing you to choose options or close the application. The browser version you are using is not recommended for this site.Please consider upgrading to the latest version of your browser by clicking one of the following links. It also provides logging functionality. 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. Reads the package power info MSR on the package specified by iNode, and returns the TDP in watts in TDP. Click "Start Log" button in the GUI to start logging. Timothy McKay, INFORMATION IN THIS DOCUMENT IS PROVIDED IN CONNECTION WITH INTEL® PRODUCTS. Do not finalize a design with this information. 96. The Intel® Power Gadget application uses a default sampling frequency of 50 milliseconds, and updates the GUI with averaged frequency and power data every second. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations.

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. Note that this function does not execute the rdtsc instruction directly, but instead returns the TSC from when the last sample was read. On recent macOS versions, after installation users need to explicitly allow the Power Gadget driver to load: 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). Install & Setup, Article ID Try these quick links to visit popular site sections. However, the frequency at which you read samples may also impact the performance of the system. The Intel® Power Gadget API also supports reading generic MSRs with ReadMSR, which returns the raw data from the MSR. To link with the Intel® Power Gadget API you simply need to include 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. A technical support representative prompts you, as part of troubleshooting an issue. *Other names and brands may be claimed as the property of others. At the beginning of the script, call "IntelPowerGadget.exe -start" and it will trigger the logging in the GUI. 000005598, Last Reviewed MSRs with function 0 (frequency) return 1 result, which represents the frequency in megahertz. The API supports reading common individual MSRs without having to specify the MSR address or read an entire sample; the supported functions are: GetIAFrequency, GetMaxTemperature, GetTemperature, and GetTDP. Intel may make changes to specifications and product descriptions at any time, without notice. If no older drivers are stored in the system, the graphics controller in device manager should now be listed as '. Intel® Power Gadget and the API are only supported on 2nd generation and later Intel® Core processors, because previous processors do not support the necessary power Model Specific Registers (MSRs). so the last bit of information regarding where the power gadget gets its temperature read outs from wasn't very helpful. For a quick review of the steps outlined in the video, read the points below. You can choose to add time-stamp to the log file name or not. Do not finalize a design with this information.

There is no method to determine if an MSR address is valid. ... Network Utility has apparently been deprecated in Mac OS Big Sur. Using a very short frequency (e.g. Only works on 2nd Generation Intel® Core™ processor family or newer. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. The parameters for the log are based on the options set in the GUI. Log power data to logfile for a period of time: Start a command a log power data to logfile until the command finish: 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. The returned data is for the data on the package specified by iNode, from the MSR specified by iMSR. To begin you must initialize the library by calling IntelEnergyLibInitialize. StopLog will cause a final call to ReadSample. Even after reinstalling Intel Power Gadget, it did not work on the Public Beta. ReadSample also reads the system time and Time Stamp Counter (TSC) at the time the sample is read. Forgot your Intel Copyright © 2019, Intel Corporation.
