Comment on Bye Intel, hi AMD! I’m done after 2 dead Intels
sugar_in_your_tea@sh.itjust.works 7 months agoIf your CPU hits 3 digits, therm throttling isn’t working properly, because it should kick in before it hits that point.
The article (or one of the linked ones) says the max design temperature is 105°C, so it doesn’t throttle until it hits that.
Which makes me think it should be able to sustain operating at that temperature. If not, Intel fucked up by speccing them too high.
I’d expect it to still throttle before getting to 105C, and then adjust to maintain a temp under 105C. If it goes above 105C, it should halt.
My intel mac’s cpu (i5-5250U) throttles to maintain 105 C
Why? It’s designed to run up to 105c.
I think it was when AMDs 7000 series CPUs were running at 95c and everyone freaked out that AMD came out and said that the CPUs are built to handle this load 24/7 365 for years on end.
And it’s not like this is new to Intel. Intel laptop CPUs have been doing this for a decade now.
CPUs should throttle as they approach the limit to prevent thermal runaway. As it gets closer to that limit, it should adjust the frequency in smaller increments until it arrives at that temp to keep the changes to temps small.
Then you misunderstand the spec. That’s the max operating temperature, not the thermal protection limit. It throttles at 105 so it doesn’t hit the limit at 115 or whatever and shut down. I can’t find a detailed spec sheet that might give an exact figure.
The chip needs to account for thermal runaway, so I’d expect it to throttle before reaching max operating temperature and then adjust so it stays within that range. So it should downclock a little around 90C or whatever, the increase as needed as it approaches 105C or whatever the max operating temp is. If it goes above that temp, it should aggressively throttle or halt, depending how how far above it went and how quickly.

When I overclock this old chip (which it was built for) it can hit over 100 with proper cooling. Some chips are hot as fuck. I think this one shuts off at 105.
