Retro review: Intel Sandy Bridge Core i7 2600K - 2018 review - Power Consumption

Power Consumption

In an IDLE state, a PC (motherboard / processor / memory / SSD/ GTX 1080) consumes roughly 45 Watts. 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, 3^rd 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.

But as you can see, power consumption ROUGHLY remained the same, however, the 8700K is a six-core proc, the Ryzen 7 1800X has eight of them!

She still runs gorgeous, stress/load temperatures are moderate with temps at the ~50 C marker on the package sensor. These, of course, are default results and not tweaked and based on Wprime on a 1024M run. The processor idles at roughly 30 Degrees C. We used a Noctua Heatpipe cooler.
