As a 3090 owner this a bit scary

Summary, the way NVidia power management is setup is to keep averages in check. High constant workload acturally get manage really well by a 3090 but on the other hand there really no checks or safety procedures for quick power spikes. Which mean if you running something that going to have many quick spikes and it very efficient(ie using every core in gpu) you can get crazy high power spikes. This happens fairly often in New world which is why it killing cards.

Obvious better made 3090 going to last longer and not burn out with these spikes but this does not bold well for long term reliability of these cards if you constantly putting these vrm under such stress.

Higher the resolution the more likely you going to have situations where the gpu will be able to use all it cores on a frame and therefore increase odds that you get a dangerous high power spike. If I remember right New worlds was doing a odd thing that it was rendering in menu way higher then even the monitor that plugged into capable of. I think I saw that behavior in one of JayTwoCents videos.

Certainly does remind me of the Fermi days. While the Nvidia driver measuring averages is quite nonsense, it should also be up to the AIBs to choose their VRMs and set their own trigger point for OCP which really should be the ultimate failsafe. There are VRMs that are certainly designed to handle such loads for long term but there are certain VRMs that are also not designed to either and I think that + shitty OCP limits + driver doing averages is where we see some 3090s get affected more so than others.

I think it all stems from Nvidia not giving AIBs enough time to make proper coolers back during Ampere launch. I remember there were a few articles about it and it was one of the reasons why Asus launched the Strix later than Evga's FTW3 and such. It will be interesting to see the longevity of these cards but I think something like a Strix or Kingpin that have high quality VRMs/PCB designs will last a long time while some like FTW3 or Gigabyte ones are gonna continue to get rekt.

Of course as next generation comes with 500 Watt Lovelace and 400 Watt RDNA 3... Things gonna get even more hectic.
