Comment on Bye Intel, hi AMD! I’m done after 2 dead Intels

Again, you misunderstand. The max operating temperature is where Intel has stated that the CPU can safely operate for extended periods of time, including accounting for situations like thermal runaway (though ideally they engineer the chip that that doesn’t happen in the first place).
If that situation does occur, the chip attempts to throttle at 105, and if that fails then it presumable halts at whatever the protection threshold is before it hits the actual damage point, as I said.

Interesting, so it only throttles at that temp? That’d a bit different than how AMD handles it IIRC, which think stops boosting around 80C or so and throttles around 90C, and the max operating temp is closer to 100C.

It’s not really that different, the exact temperatures are slightly higher but most intel processors will boost up to 105C, then start pulling the boost back and throttling to maintain that 105C as a maximum, and if that’s not possible they’ll halt at 110C.
AMD does the same, just the temps are (for the one specific CPU I remember them for) 80-85C for dialing down the boost, 90C for throttling below the normal freq, and 95C for TjMax which either halts the system or just drops the power usage so low it doesn’t matter - I’m not about to take a heatgun to my CPU to see what it does as it isn’t capable of hitting that on its own.

The 7000 series had the Intel behavior of just clocking up until like 105C and staying there indefinitely
That’s why people thought the 9000 series was disappointment - AMD went back to balancing power efficiency and performance

Yes.
Whether Intel fucked up by saying “oh yeah works great up to 105” if that isn’t actually true is another question, as I mentioned.
