    Be nice if AMD switched to silver-based solder. Might cost a few extra $$$ per CPU but they'd run a lot colder.

    At least AMD is not using the TIM that Intel used in some older CPUs.

    Not worth it, use PBO2 Tuner with -30 on all cores and results are same, 10-13C less under load.

    Have we ever seen a single CPU that did not perform better delidded?

    How exactly is this worth it on a CPU that can't be overclocked? Who cares if the temperature drops a lot of it's already within a safe operating range? Rather than get the tools to delid, I'd rather spend extra on a better cooler. Or better yet, I'd rather just undervolt it - no risk, less heat output, and no effort.

    Exactly my point - it is enough. Not sure how Madness7771 thinks otherwise.

    delided my i7 4790K and got a 25C reduction, 10C is not worth the risk IMO

    Also I slid off a few SMDs on my 4790K, yet it still continue to work to this day :D (gave it to my brother and he play game on his PC daily)

    wouldn't say that with 90c peak

    90C is within safe operating range and likely under boost clocks. It's fine.

    You mean 90C is when the chip throttles itself

    And like I said in my first post, if that bothers you, undervolt the chip to give yourself more headroom...

    shouldn't have to undervolt with a d14,but I'd take that over delidding

    I have delidded five 12th gen cpus. With the proper tool the risk is quite low. It's one of those things where if its unknown territory its considered "not worth the risk" 10-15c is no joke. The last 12600K build I did hit 5.3/4.3 on an arctic freezer II. Obviously he got the god bin but still. Had a 13c drop on my 12900K at 5.2/4.0 82c max avx load, worth.

    Its voltage can't be adjusted, at least not in the BIOS, it either can't be changed or if it is changed it does nothing. But yes I agree, it's somewhat pointless considering at worst it goes just over 70C in games with my ancient NH-D15 as its cooler.
    I don't remember my synthetic tests' exact details, but IIRC I did hit the 90C throttle point in something but it didn't make a huge difference, it boosted ~100MHz-150MHz less than the max it hits in games. Not ideal, but not a deal breaker either.

    Does the 5800X3D not respond to colder temperatures with higher boost clocks like Ryzen 3000 does? I know der8uaer did testing on this on the past.

    Well yes it does, as shown in the chart of the OP. Looks like improvements on keeping max boost clock in the first place (4300 min vs. 4450 min while 4450 is max for both delidded and not).

    Although I personally expected AMD magic self overclocking to actively get a higher boost clock out of a 10°C / 12.5% cooler CPU, but I guess that feature was deactivated for testing purposes of course. At least I hope so.
