The overheating of the reference Radeon RX 7900 XTX graphics cards is really to blame for the defect in the evaporation chamber, as enthusiasts suggested. This information was confirmed by AMD Vice President Scott Herkelman (Scott Herkelman) in an interview with PCWorld.
According to Mr. Herkelman, the defect, namely the lack of liquid inside, is typical for a small batch of evaporation chambers. Currently, AMD, together with AIB partners, invites owners of problematic Radeon RX 7900 XTX reference design to contact support for a replacement video card. The company emphasizes that there will be enough serviceable video cards for everyone, which means that rumors about the depletion of stocks of cards are incorrect.
Recall that soon after the start of sales of AMD RDNA 3 3D accelerators, new owners of the Radeon RX 7900 XTX began to receive complaints about overheating of the video card. The temperature of the GPU Hotspot easily rose to 110°C, which was often accompanied by a drop in performance. In the course of informal experiments, it was possible to find out that the main cause of overheating is a defect in the evaporation chamber. However, AMD was in no hurry to confirm this hypothesis.
