Ah, the year of unreasonably overpriced, poorly constructed hardware. And we'll still buy them. Happy new year everyone!

It seems totally bizarre that the QA/QC process allowed this, surely there is a QA/QC process.

Not just the flagship, but also the XT, which was tested by IgorsLab.

Well guess depends what QA/QC consists of. If all test benches aren't pc cases, which has card installed horizontally then under vertically installed conditions you wouldn't see any issues with hotspot and would appear the vapour chamber is working as it should be. Der8auer even himself dismissed the vapour chamber been the problem in his original testing of the card, when user who sold it to him said he thinks vapour chamber on the card is fubar. It's only after relooking at the issue has he discovered it is the vapour chamber, after knocking off all other potential issues like mounting pressure, improper thermal paste application. Gravity seems alleviate whatever is causing the vapour chamber not to function at 100%, one can assume maybe isn't enough liquid inside an it needs assistance of gravity to travel back from cold to hot side of the vapour chamber? (think of pump with not enough head pressure to overcome the block restrictions would be one way describing it) who knows obviously engineers who designed it, didn't fully understand it either. Der8auer kinda elaborated at it too by pointing at vapour chamber itself how it narrows towards the end, maybe it's too restrictive to vapour flow.

Seems like a bloodbath if they have to replace all coolers

AMD entering 2023 with the wrong foot forward.

Might have to redesign the entire cooler, if it's too restrictive to vapour flow and wasn't manufacturing defect, basically it was designed defective. AMD would have difficult choice to make recall all cards for cooler replacement? offer replacing all reference cards for AIB model instead? basically unlaunching all reference cards.

QA/QC should be thinking "So What", to every possible scenario and every possible permutation of each scenario. Whether it was time constraints or financially driven, corners seem to have been cut and this may have significant implications.

Neither is a cheap or easy solution. You just know that there is a somebody somewhere, very low down the pecking order who would have raised this, and was ignored.

Well it's been overlooked, perhaps by same people who said 110c hotspot was normal behaviour? I would imagine whoever worked on the cooler design/construction is going be fired.

Well redesigning a cooler an QA/QC testing it with potentially same team who approved the original cooler? would you trust them get it right second time round. Also its going take time to redesign and manufacturer a new cooler, that's why I picture AMD just unlaunching the reference cards and sending more dies to AIB's an just doing direct replacements, would be lot faster than trying redesign and test new cooler potentially cheaper and less reputational harm.

I am a bit worried that AMD did in fact find this issue but they tested such a small sample size that they considered it within standard deviation of their RMA.

Truth be told, most people throughout GPU history, avoided the reference models, preferring custom cards with better cooling, OC, power delivery and aesthetics. People who considered the reference model would usually be people that wanted the cheapest. Or who would want a standard PCB to install a water cooler.

Nothing wrong with buying the cheapest option that work well enough, in fact the majority of buyers do so 😉

True, but with most GPUs ever released, the custom solutions were significantly better and well worth the extra cost.

man the reference would be my #1 pick this time, the card is a looker I'd even buy this box alone to put on a shelf https://www.eteknix.com/wp-content/uploads/2022/12/7900-xtx-box-front-1.jpg

I think that's part of the reason why this thing with the reference cooler hit harder. For a while, it really looked like was going to be great solution. So the disappointment was bigger, than if the reference cooler was like the Radeon 290.

the kicker is the manufacturer of the block probably warned amd of orientation issues.
