Power Consumption

Power Consumption

We show energy consumption based on a 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.

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.

Temperatures

The reason we do not table up temperature results is that we'd need to apply the same cooling over and over on all platforms. Also, coolers (RPM) react differently to TDP and variables like BIOS. But also all motherboards apply different RPM levels and temperature deltas.

Overall stress/load temperatures are moderate with temps at the 65 C marker. These, of course, are default results and not tweaked and based on Wprime on a 1024M run. We used our trusty Corsair H110 here for cooling (liquid cooling LCS kit).
