at 700Celcius i dont think you get 3rd degree burns anymore, probably catch on fire, or “charred remains”

Once they hit temperatures of 200 degrees Celsius, most tend to fail.
Is there a unit conversion error here? Or do I massively misunderstand what “most” means?
200 F is 93 C so I’m going to guess unit conversion
Perhaps they’re talking about junction temperatures, but even then specialist components can only do 175 degrees C briefly.

Is “all” considered to be a subset of “most”?
100% of processors fail, which technically is more than 50%
All processors are computer chips, not all computer chips are processors.
ETA: The article seems to mention processors, but this appears to be a memory chip advancement.
My Ryzen 9 had a default boost limit of 90 °C, which caused a lot of stress to the rest of the cooling system in my PC but it didn’t seem to have any problem running like that for a few hours. (Fortunately you can crank it down to something a bit more sensible in the BIOS.) My laptop will spike briefly over 100 °C, but only for a second or two. I can see the ‘failure’ temperature being a bit higher, but 200 °C seems unreasonably hot.

Yeah, that’s kind of where my confusion comes from. 93C seems pretty low for a failure temp, my old AMD started throttling at around 90C, but I fully recognize that is pretty hot for a processor and “most” would fall below that. Unless they’re meaning temperature at the transistors most fail at 200C. I can definitely see a temperature sensor reading a few 10s of C different from the actual working interface of transistors, where 90C might mean the transistors are around 150C.
Too bad that most CPUs can run at up to 100°C and some even a bit higher. I think I read so.ewhere 125°C fpr some special OC cpu chips

That’s one way to solve the AI data center cooling issue. Of course it would make the data centers deadly to support staff, so I anticipate that will make it to market.

There’s a reason they run laptops on the ISS, space data centres are a pipe dream without power generation and all the other necessary infrastructure.

700degrees would likely degrade the structures housing the chips. and would likely make it even more expensive.

No, it is potato. That’s why it still runs at the temperature of a baked potato after I let it cool for an hour
