Intel Power Gadget

[Karri Weston]

<div>Does it look like that from your point of view? It's listed as a power package. I'm not sure where you are getting the python information. I honestly just got tired of tracking utilities for computers here. There's too many problem zones. I can assume you also found the container at Hub.</div><div></div><div></div><div></div><div></div><div></div><div>intel power gadget</div><div></div><div>Download Zip: https://t.co/05YmlEuaSw </div><div></div><div></div><div>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. See the following to learn more:</div><div></div><div></div><div>Intel Power Gadget version 3.5 is composed of components, drivers, and libraries, which access and post-process the processor energy counter to return an accurate power usage in Watts, the temperature in Celsius, as well as the frequency in GHz (as seen in the image below):</div><div></div><div></div><div>Intel Power Gadget is a software-based power-usage monitoring tool enabled for 2nd-generation Intel Core processors or later. It is supported on Windows and 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.</div><div></div><div></div><div>The power gadget doesn't support your CPU though: the RAPL initialisation code is table-driven, and it doesn't know about Skylake CPUs (or even Broadwell). It only knows about Sandy Bridge, Ivy Bridge and Haswell (and even then, not all Haswell CPUs)...</div><div></div><div></div><div></div><div></div><div></div><div></div><div>The power gadget hasn't been updated in a while for Linux (current version 2.5, but on OSX and Windows the current version is 3.0.x) - but you can use turbostat --debug to see a lot of the same information, including per-core RAPL measurements, etc. Here's a man page, but the man page on your system is more likely to be up-to-date.</div><div></div><div></div><div>Usually, conventional ways to estimate the power or energy usage of the processor are tanglesome and complicated, which include the special purpose tools and instruments on the devices or the third-party software. However, this article will introduce you to an excellent replacement -- Intel Power Gadget, which is powerful and easy to use.</div><div></div><div></div><div>Intel Power Gadget is a software-based power usage monitoring tool developed by Intel Inc. It includes an application, driver, and libraries to monitor and estimate the real-time processor package power information in watts using the energy counters in the processor.</div><div></div><div></div><div>Designed for end-users, independent software vendors, and original equipment manufacturers, the Intel Power Gadget is able to provide a precise estimation of how much power a software consumes without any errors.</div><div></div><div></div><div>With the release of Intel Power Gadget for MacBook, MacBook Pro, and MacBook Air, obtaining clear statistics and performance of CPU is not wishful thinking anymore. You can apply this versatile helper to evaluate power information on different platforms, such as laptops, desktops, and servers, moreover, it can be used on both Windows and macOS, like macOS Monterey, Big Sur, and Catalina.</div><div></div><div></div><div>Intel Power Gadget for MacBook, MacBook Pro, and MacBook Air features a nice UI, which lists detailed information and statistics including CPU power, frequency, temperature, and utilization. Compared to Activity Monitor, it is easier for users to figure out the CPU conditions.</div><div></div><div></div><div>MX Power Gadget is almost a 1:1 copy of the Intel Power Gadget and a GUI for power metrics, presenting the information and statistics in a nice format for better visibility. You can install it and monitor your devices' performance according to the statistics and information provided by this fabulous tool.</div><div></div><div></div><div>The main strengths of this tool are (a) it works on Windows, unlike mostother power-related tools, and (b) it shows this data in graph form,which is occasionally useful. On Mac and Linux, tools/power/rapltools/power/rapl is probably a better toolto use.</div><div></div><div></div><div>Temperature: Shows the package temperature. This is interesting,but again not useful for power profiling purposes. Specifically,the temperature is a proxy measurement that is affected byprocessor power consumption, rather than one that affects it,which makes it even less useful than most proxy measurements.</div><div></div><div></div><div>Version 3.0 (available on Mac and Windows, but not on Linux) alsoexposes an API from which the same measurements can be extractedprogrammatically. At one point the Gecko Profiler used thisAPIon Windows to implement experimental package power estimates.Unfortunately, the Gecko profiler takes 1000 samples per second ondesktop and is CPU intensive and so is likely to skew the RAPL estimatessignificantly, so the API integration was removed. The API is otherwiseunlikely to be of interest to Mozilla developers.</div><div></div><div></div><div>When measuring energy consumption, one cannot isolate the software from the system where it is running. Thus, it is extremely important that we reduce the extra work in your device to the bare minimum. Make sure that no unnecessary applications or processes are running on your device. Also, if you are running in a battery-powered device, it is usually recommended to remove the power plug as it might affect measurements in some setups.</div><div></div><div></div><div>The power data will be collected and stored in a CSV file under your Documents folder (default behaviour). I have run a small test and, in my case, it stored the data in the file /Documents/PwrData_2021-2-19_17-16-10.csv.</div><div></div><div></div><div>where is the name of the CSV file where the power data is stored and is the actual command you want to execute. It could be, for example, your test script. For simplicity, try running a sleep command for a few seconds:</div><div></div><div></div><div>Similar to the previous tools, powerstat is just another nice wrapper around an Intel library named RAPL, which stands for Running Average Power Limit. However, it provides a simple interface to execute it using the command line. You can run a power measurement with the following:</div><div></div><div></div><div>In this case, the summary tells us that the power consumption (different from energy consumption!) of the execution was on average \(8.38\textW\) in the 60 samples of 1 second. Based on this data, we can compute the total energy consumption.</div><div></div><div></div><div>PowerTOP is another powerful tool to measure and monitor energy consumption. Its main advantage is the ability to estimate energy consumption in devices with an AMD processor. However, PowerTOP use cases go beyond simple energy consumption measurements. For example, it provides an interactive mode that allows users to fine-tune power management settings in their Linux system. Hence, it can sometimes be a bit overwhelming, but overall a great alternative.</div><div></div><div></div><div>This means that, on average, our processor and main memory leveraged 5.43W of power during the 20 seconds of execution. As mentioned before, this is not the energy consumption (yet!). The total energy consumption in this measurement is computed by multiplying the average power by the duration of the measurement:</div><div></div><div></div><div>Another quick way of obtaining energy and power measurements from Intel processors, is through Likwid.At its heart, Likwid uses the RAPL interface, developed by Intel, to fetch energy and power measurementsfrom different domains of a CPU.</div><div></div><div></div><div>Compared to Perf, Likwid does not offer an option such as -r to run a test mutliple of times.However, it offers power apart form energy measurements.Moreover, Likwid offers other options such as temperature monitoring per thread.</div><div></div><div></div><div>A very easy to useful command-line tool to obtain Nvidia GPUs power-related information along with other information such as memory usage, temperature, and many more.The nvidia-smi tool is particularly useful in measuring the power consumption of GPU-intensive applications such as training a deep learning model, watching a video, playing a game, and so on.</div><div></div><div></div><div>The above commands will start a model train in the background and, then, will print the power usageof the GPU in the foreground on each second (--loop-ms=1000).The --format=csv can be used to collect data in a CSV format.There are many available options to nvidia-smi and a rich documentation can be found online.</div><div></div><div></div><div>So far, we have covered six energy profilers. Each one of them has advantages and disadvantages. Most of all, they have particular requirements that make them suitable or not to your particular case. Unfortunately, I have not come across a single solution that works for all devices and operative systems. The problem lies mostly in the fact that Intel and AMD computer architectures require a different approach to collect power data.</div><div></div><div></div><div>The latest-gen MacBook Pros retain the same hardware chassis design but feature new, power hungrier, quad-core and six-core CPUs. Particularly on the highest-end model, the 15-inch MacBook Pro with Core i9 chip, a number of reviewers have noted severe performance throttling, with the Power Gadget reporting the processors are dropping below their base clock speed with longer-running tasks like video export.</div><div></div><div></div><div>When i am answering this question you have 3 days remaining. If you feel as though it seems an issue than maybe ask for an exchange. However the Apple laptops run hot because they have powerful CPUs which generate a lot of heat and those CPUs are in an extremely thin laptop so heat builds up quickly. This is perfectly normal. The laptop will shutdown if the CPUs get to a critical temperature so if this is not happening, then just enjoy your laptop. I've rarely seen a computer shutdown to due overheating.</div><div></div><div></div><div>The main strengths of this tool are (a) it works on Windows, unlike most other power-related tools, and (b) it shows this data in graph form, which is occasionally useful. On Mac and Linux, tools/power/rapl is probably a better tool to use.</div><div></div><div></div><div>Intel Power Gadget can also log these results to a file. This feature has been used in energia, Roberto Vitillo's tool for systematically measuring differential power usage between different browsers. (An energia dashboard can be seen here; please note that the data has not been updated since early 2014.)</div><div></div><div> df19127ead</div>
