AMD’s RX 7900 XTX The flagship GPU could have a difficulty with its steam room, which can be the reason for alarming experiences of severely excessive hotspot temperatures plaguing the graphics card.
Tom’s Hardware (opens in new tab) overclocking specialist Der8auer bought 4 RX 7900 XTX graphics playing cards (with reference design) and ran a sequence of checks (one video (opens in new tab) on his YouTube channel) to pinpoint what’s behind the overheating points which have been pinpointed in some instances (exhibiting temperatures reaching 110C).
Der8auer found that with no less than these 4 graphics playing cards, mounting the RX 7900 XTX vertically runs cooler than horizontally, however that wasn’t the entire story – there have been complaints from individuals working a vertically mounted 7900 XTX about excessive hotspot temperatures. , too (and for Der8auer in a single case, a vertically mounted card noticed reasonably excessive temperature spikes).
The query then was what was the true underlying trigger of those hotspots, though the meeting configuration appeared to have an impact.
Der8auer explored varied theories, equivalent to whether or not the load of the heatsink was problematic, pulling it off the board, or whether or not the mounting stress was inadequate or if it was certainly a difficulty with the thermal paste. Nonetheless, after some very thorough testing, he dominated out all these points as potential causes.
In keeping with Derauer, this left just one wrongdoer as the basis trigger: the steam room. He instructed that the stress contained in the steam room could be incorrect, or that the incorrect quantity of fluid might need been used contained in the room, or that there could be a easy design flaw in the best way the room was constructed.
Inside follow up video (opens in new tab) Der8auer says there is not a bodily design flaw with the vapor chamber, however reasonably AMD is not utilizing sufficient fluid inside. Acknowledging that he’s on no account an professional on the topic, this conclusion was reached together with Igor’s Lab and a steam room builder – however that is nonetheless an assumption, beware, so we should proceed with excessive warning right here.
Evaluation: A much bigger potential meltdown than Nvidia’s RTX 4090?
Naturally, we do not wish to draw any conclusions primarily based on a couple of YouTube movies that solely contain 4 7900 XTXs. graphics cards, and we have to see additional investigation of this subject – ideally from AMD, in fact its investigation is ongoing. Nonetheless, Der8auer may be very agency in his declare on the matter right here and believes that AMD could also be in “massive bother” on this regard.
primarily as a result of in contrast Nvidia melt adapter problem with RTX 4090Though round 50 occasions have been recorded, there are lots of extra experiences of this overheating flaw in AMD’s new flagship.
That is why Der8auer means that AMD cannot actually take care of graphics playing cards affected by RMA (return and change); and as a substitute, Group Pink could must recall the affected RX 7900 XTX fashions (these with the reference design and heatsink – third-party customized designs differ in fact).
As for what’s going to really occur, we’ll simply have to observe this space. However proper now, these are significantly worrying rumors for AMD as the corporate is presently investigating these points as we’re speaking about.
The final assertion we heard from AMD on the matter was: “We’re investigating experiences of some AMD Radeon RX 7900 XTX graphics playing cards (reference fashions made by AMD) reaching 110C and throttling. Thermal throttling could have an effect on the efficiency of the cardboard by lowering clock speeds, however the graphics card should be used.”
Group Pink then suggested affected events to contact AMD help, however you’ll be able to solely do that by cellphone presently, which hasn’t gone too nicely with the neighborhood, because the e-ticket system is down (till Jan 5) for upkeep. None of it is a nice search for AMD, particularly when you think about Group Pink’s meltdown adapter frags for Nvidia as a part of the formation. RDNA 3 GPU lunch.
