The Intel® Power Gadget API also supports reading generic MSRs with ReadMSR, which returns the raw data from the MSR. The driver can also be called the Intel® Graphics Media Accelerator Driver (Intel® GMA Driver). Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors.
Last Updated:12/13/2012. 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. However, the frequency at which you read samples may also impact the performance of the system. save hide report. 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). 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). Forgot your Intel Stops saving data and writes all saved data to the file specified by the call to StartLog. Find the Intel Graphics Driver. 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. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. These are included in the Intel® Power Gadget installer, or as a standalone API installer. Enter the following command, and press Enter (requires a password to complete): Provides processor power (Watts), temperature (Celsius) and frequency (MHz) in real-time via graph displayed in the GUI. 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). The instantaneous processor frequency can change significantly from moment to moment. 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.

The API supports sampling of specific Model Specific Registers (MSRs). MSRs with function 1 (power) return 3 results, which represent the average power in watts, cumulative energy in Joules, and cumulative energy in milliwatt-hours. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. For Windows Using the Intel® Power Gadget API on Windows There is no method to determine if an MSR address is valid. By signing in, you agree to our Terms of Service.

The sample data from ReadSample can be logged to a file. Starting with version 3.5 and going forward, only the 64-bit version and Windows 8* will be supported. It could be IntelliJ IDEA.app or IdeaIC.app. Returns in szName the name of the MSR specified by iMsr.
