There is drama bubbling about some older AMD GPUs dying a physical death. Reports from China indicate a possible defect in the Navi 21 graphics processor. This chip powers the Radeon RX 6800 and RX 6900 XT video cards. A board partner there shared pictures showing cracked or swollen GPU cores. The company claims it gets these broken Navi 21 units daily from repairs.

The damage is described as a physical deformity of the silicon itself, not a circuit board problem. This manufacturer says other brands often reject warranty claims for such visible core damage. They keep replacing them for their own customers and have saved a pile of failed dies as proof. Videos online also show similar cracked and bulging chips, backing up the story.

The exact cause remains unknown. It could be from thermal stress or something wrong with the packaging process. AMD has not commented publicly on these specific claims. While not confirmed as a universal issue, it suggests potential long-term reliability worries for certain RX 6000 series models. Anyone with a sudden card failure might want to take clear photos before seeking an RMA.
