About the AMD RX 7900 XTX, say that it is the most recent top of the range launched by the company. This has 6144 Stream Processors and 96 RT Cores working at a base frequency of 1855 MHz and reaching 2499 MHz in Boost mode. This graphics card is accompanied by 24 GB of GDDR6 memory.
Does the AMD RX 7900 XTX have a manufacturing defect?
The temperature of this new graphics card has drawn a lot of attention from users. let them register temperatures up to 110ºC with the fans fully operational this is not normal. From the company they have already commented that the temperatures are in range, that there is nothing to worry about in the face of the return requests they have received.
Faced with this chaos, Der8auer wanted to verify if the problems are real and if they are the most common. He has had access to a total of 4 different RX 7900 XTX models. To verify all the possibilities, you have installed each graphics card in portrait and landscape. In addition, it has reduced the distance between the heatsink and the GPU, it has changed the thermal paste and a lot of other things. after all these teststhe graph follows reaching 110 ºCthere is nothing that can be done.
In his opinion, the issue could be in the system of vapor chambers of the sink. It could be that the material was of poor quality or internally they are not well. This would be generating a bad coolant flow internal of these value chambers and generating these temperature problems.
We cannot take anything for granted, as the design flaw is solely Der8auer’s opinion. If a third-party heatsink is manufactured or designed for this graphics card, we could give more accurate data. At the moment, it is only a guess given by one of the most reputable overclockers and analysts in the world.
He has also highlighted that he has found a total of 48 cases of thermal problems in the RX 7900 XTX. It is possible that little by little, more users will carry out tests and upload their data.
Is this temperature really a problem?
We may think that the answer is simple, but it is something more complex than an affirmation or denial. Silicon has no problem working at 100 ºC in fact, it can withstand even more heat. Where we could have problems is in the soldering between the PCB and the GPU, and the memories.
Usually, the solders are made of tin. Said material is in a solid state up to certain temperatures and then becomes a liquid. The process of going from solid to liquid, and back again, can end up damaging the weld. Hence, certain products are reballed, which can solve the problem. Note: this is a simplification then this is more complex.
If AMD knows about the problem and they are built to withstand these temperatures, we shouldn’t have any problems. However, drawing conclusions is difficult.
