Power Consumption and temperatures

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. 




I 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.


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. Therefore we simply plot a temperature stress test. Good news btw, AMD is no longer making a distinction between Tdie and Tctl (offset for fan activity). So there is just one variable to monitor, ergo what you see is what you get.



 Above: Stock WRAITH AMD cooler on the 3800X. We reach a max temp of 73 Degrees C (Tdie). That is running multiple 1024M Prime tests.
