They easily can though. Just put them in a case with no airflow or pressed up against another card or a wall or something. This is why I think saying 110°C is expected is inappropriate; it is not expected, you yourself just said it wasn't expected. This is my only criticism, using junction temps is a good thing and 110°C is not an unreasonable junction temperature to start throttling at.

The "First off..." makes it sounds like you are arguing with me but then you basically agree with all my points?

The real GPU hot spot temperatures are probably very similar in both cases, with AMD probably being safer since it limits the hottest spot to safe temperatures while Nvidia has to hope the expected delta between the hottest spot and the edge is accurate. However, if your GPU is running at 110°C all the time while gaming then something is probably wrong or at least should be improved, like if the temperature was pegged at 84/88°C on an Nvidia GPU. The case might be too restrictive or the GPU need repasting or something.

It is great to be able to see the junction temperature, and it is safer for the silicon to have the GPU throttle based on it instead of the edge temperature, but at the same time anyone who's GPU is holding junction temps at 110°C should not think "AMD said 110°C is normal" and ignore it.
110c is normal for the junction temp. Pretty much every Radeon VII hit 110c with the stock fan profile. I ran it at stock that ran between 100-110c for a bit over a month while waiting for EK to release their block. The card absolute shut off temperature isn't until 120c. It doesn't throttle until it hits 115c.

The thermal benchmarks I have seen from reviews of Navi do not show it normally running at 110°C junction temp at defaults. Why is Radeon VII being used as a datapoint for Navi?

Edit: 100°C is reasonable, we wouldn't be worried about edge temps at 74/78°C either. 100°C is not 110°C. Navi does start throttling at 110°C, unlike Radeon VII.

AMD's 7nm parts can handle 110c and we can see they are designed to run that high since they don't throttle until 115c. The reviews you've seen are open air cooling. AMD went with a blower for air restricted cases.
