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.
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.
Intel Power Gadget for macOS 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. A command line version of the tool (PowerLog3.0.exe) is also included
Note: 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.
