Power Consumption and temperatures

Power Consumption

We show energy consumption based on the entire PC (motherboard / processor / graphics card / memory / SSD). This number depends and will vary per motherboard (added ICs / controllers / wifi / Bluetooth) and PSU (efficiency). Keep in mind that we measure the ENTIRE PC, not just the processor's power consumption. Your average PC can differ from our numbers if you add optical drives, HDDs, soundcards etc.  Also, do not rule out anything RGB these days; an RGB lit motherboard, Keyboard, Liquid cooler, and mouse these days can easily add 10 to 15 Watts of power consumption to that Wattage budget. 





We want to make it very clear that power consumption measurements will differ per PC and setup. Your attached components use power but your motherboard can also have additional ICs installed like an audio controller, 3rd party chips, network controllers, extra SATA controllers, extra USB controllers, and so on. These parts all consume power, so these results are a subjective indication. Next to that, we stress all CPU cores 100% and thus show peak power consumption. Unless you transcode video with the right software your average power consumption will be much lower.


We don't compare temperature data since we'd have to apply identical cooling to all platforms over and over. Furthermore, coolers (RPM) respond differently to TDP and variables set in your motherboard BIOS. As a result, we simply do a temperature stress test.



Above, you can see the load test results based on a Corsair H100i RGB Elite (2022) we reviewed. The LCS we use is dubbed a performance cooler (not enthusiasts). You can see thermals are a notch better with the 120W TDP processors. One max per core multiplier is now 57.5 MHz. Long story short, a good-performance LCS will help you achieve the best turbo boost results.

Please note that PPT (max power consumption) is roughly 162W. The temperature results are pretty okay. The TJMax temperature design for this processor is 89 Degrees Celcius.
