Core i9 12900K processor review - Power Consumption

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. 

Note: we've seen energy consumption differ quite a lot in between brands of motherboards.

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. 

Above can see that once we average out the cores over system power draw per core, we're looking at total system power + CPU cores stressed / the number of cores.

Temperatures

The reason we do not table up temperature results is that we'd need to apply identical cooling over and over on all platforms. Also, coolers (RPM) react differently to TDP and variables like BIOS on all motherboards let alone brands. The processor peaks towards ~70 Degrees C under full load on the processor package, this temperature is measured during a looped Prime95 1024M runs.  We use a 360mm LCS.
