A fake AMD Ryzen 7 9800X3D processor was recently discovered through AMD's after-sales service inspection in China after a customer reported their CPU wouldn't boot. The counterfeit unit revealed several technical discrepancies that distinguish it from genuine processors, though these differences are difficult to spot without detailed examination. While authentic Ryzen 7 9800X3D processors use PCB number 33050, the counterfeit unit featured PCB number 32546—a designation typically associated with Ryzen 7000 series R7 or R9 processors. This suggests the counterfeiters may be repurposing older generation chips or PCBs to create fake 9000 series processors. The physical appearance of the counterfeit unit showed additional inconsistencies.

Genuine Ryzen 9000 series processors feature a distinctive blue PCB, while the fake unit displayed a dark green coloration characteristic of older models. Component patches adjacent to the PCB also failed to match the standard configuration of the Ryzen 9000 series. In a notable error, some counterfeit units were mislabeled as "Ryzen 9 9800X3D"—a model number that doesn't exist in AMD's product lineup. For comparison, legitimate Ryzen 7 9800X3D units can be identified by their blue-tinted PCB, while older models like the R9 7900X and R7 7700X feature dark green PCBs. The information was initially shared on Chiphell by sources within the PCB manufacturing industry, who provided side-by-side comparisons of authentic and counterfeit units. AMD's after-sales service has confirmed that processors purchased outside official distribution channels will not receive warranty support or service protection. Buyers should buy CPUs only thought official sale distributors to avoid such cases.
