With any intel cpu from 12th gen and afterwards, idle power draw should be around 3 to 5 watts and browsing the web or doing simple spreadsheet work etc should be between 8 and 15. That's if you have set up C states properly and balanced power plan.
My 12900k with 2 videos streaming (YouTube and twitch) browsing the web while on a discord call is below 10 watts.
Nobody can tell you that, and it entirely depends on the amperage going through your cpu, temperatures are not that important. If you are running prime 95 pulling 400 watts at 100c I don't think it will last more than a year.
Define damage. Just using your cpu for anything basically damages it. Electromigrarion happens even at 50c while your cpu is idle. Obviously higher temps and higher amperage accelerates it.
The question is why would you want to run it 24/7 at 100c? Set an 80c power limit and you are good to go.
Intel cpus are incredibly easy to cool, but at the same time it left without any power limit they will literally draw up to 400 watts in multithreaded workloads. I'm running a U12A on a 14900k and it works like a charm, but again, it depends on what your goal is. By maxing the fans and letting the cpu get to 100c I get around 43k in cbr23. That's both loud and hot. But on the other hand, dropping to a score of 40k will bring the temps down to 80c and the fans are just chilling.
Your power readings are wrong. You need to setup DC LL properly from the bios to get accurate power readings
If / when Intel reaches node parity and stacked cache, it's going to send AMD back to the stone age again.
It's fine, you are not going - cannot overclock a 14900k frankly.
What benchmarks are those? I can test it, let's go and see same performance at 2/3 the power.
So you are buying amd cpus that don't have apo either. Great idea...
Great idea, disable ecores and lose gaming performance....
If you like tuning your CPU, then yeah, a tuned 12900k (mostly memory tuning, the rest stock) is as fast as the 7800x 3d in most popular games (TLOU , Cyberpunk, Spiderman remastered, hogwarts , Starfield etc.). A 14900k is way faster than that. Also, as you said yourself - longevity.
There is no cpu that needs an aio. I have a U12A on a 14900k runs great.
