    To benefit from boosting the boost, to boost the boost of Rocket Lake up to the moon, CPU must work in Intel spec. temp. range, without a $$TEC, I think you can´t boost nothing and btw Intel is boosting themselves sick, but reviews will show.

    Edit: now we have a 1000W modded HOF cards + Intel ABT+TVB + cooling device situation where a new PSU must be invented.1h gaming = 1$, maybe even more.

    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

    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.

    Trying some Memory OC on my 11700k :)
