intel is still very efficient for a lot of home/gaming pc usages it's that max stress test power draw with avx on that's utterly ridiculous. but yeah,I don't think people who choose ryzens over intel for home rigs because of power savings realize this idle https://pclab.pl/zdjecia/artykuly/mbrzostek/2020/cml_s/wykresy/power_idle.svg video playback https://pclab.pl/zdjecia/artykuly/mbrzostek/2020/cml_s/wykresy/power_video.svg gaming https://pclab.pl/zdjecia/artykuly/mbrzostek/2020/cml_s/wykresy/power_3d.svg all values are for the whole system w. rtx2080 here's a great test,albeit in Polish,telling you exactly what every tasks costs in energy https://pclab.pl/art84541.html you won't learn this from memes or youtube trash this is power draw for every minute of the cpu sitting in idle https://pclab.pl/zdjecia/artykuly/mbrzostek/2020/cpu_energy/idle_60sek.svg
Not sure where those are from but those idle temps don’t look right. My Ryzen 5950x idles at 36-39°C with PBO enabled on an AIO liquid cooler. Also, my UPS shows ~40-60W, including having 2 monitors plugged in.

those are power draw charts sorry they're in polish,can't translate charts

Hmm interesting. I hope that this will be looked at with the reviews, quite curious to see if that actually does make a difference in regards to different workloads (boosting higher in gaming, more average boost across 4 cores when doing calculation workloads etc).
And I thought that actual issue was in cores boosting for too long and sustaining boost which ate much more power on average than what Spec Sheet of given CPU said. If one gets better cooling, this thing will do what? Eat 280W under load indefinitely? So, why is everyone talking about idle power draw of entire systems? There are way too many factors and settings which affect idle on both AMD and intel. To the topic of idle. When I had 2700X, I did few tests. And limiting CPU to 15W resulted in all cores never going above 600MHz and actual power draw being 16.5W as CPU simply could not eat less. With 25W limit, all core boost was 1.66GHz. 45W got all cores to 3GHz. 65W got all cores to 3.5GHz. But 3900X gets all cores to 4GHz while it eats 65W. And yes, with OC, both could easily eat 220W without gaining more than 125MHz above standard boost clocks. So, OC for Zen+/Zen2 was not really worth it. But I can't complain about power efficiency when it matters.
