AMD Ryzen 7 5800X review - 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.

Temperatures

The reason we do not table up temperature results and compare 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 defined in your motherboard BIOS. Therefore we simply plot a temperature stress test. 

We make use of a 240mm LCS cooler, you can see that the processor runs ~73C, under heavy load.

 Above: Ryzen 7 5800X, six cores can hit 48.5x.
