Helping matters further is that both CPUs share very similar CPU specifications, making it difficult for novice users to discover which CPU is really inside. The Ryzen 5 7430U and 5500U feature six cores and 12 threads, a 15W TDP, and very similar clock speeds. Where they differ the most is in the architecture and L3 cache capacity; the 7430U comes with Zen 3 cores and 16MB of L3 cache, and the 5500U comes with Zen 2 cores and 8MB of L3 cache.
Chuwi attempted to downplay the issue by suggesting there was a mix-up in product batches, but Chuwi was caught changing the processor label at the firmware level, which is something that does not happen by accident. Furthermore, Chuwi allegedly demanded that Notebookcheck remove information about the scandal from its website.
Chuwi has since announced a recall on all of its products with mislabeled CPUs, and is offering a full refund for owners of the affected products. These items are the CoreBook X, CoreBook Plus, and Ubox mini PC.
Despite all of the evidence piling against Chuwi, another manufacturer has potentially succumbed to the same problem. ComputerBase discovered a forum thread where two owners of a Nikear A15 Pro laptop claim they have a mislabeled 7430U chip inside their laptops. Computerbase noted that the affected Nikear laptop and Chuwi CoreBook X laptop take advantage of the same PCB inside.
If this is all true, the problem might actually lie with the PCB manufacturer rather than the laptop makers themselves. The only problem with this information is it was taken from a forum post and has not been confirmed by a reputable outlet or manufacturer. As a result, take this information with a grain of salt.

BTS2026 This might be the most downvoted comment – but – AMD needs to be held accountable for their processor naming conventions… Ryzen 5 7600X3D and Ryzen 7 7700X… Some if not most regular consumers are going to see AMD 7600 or AMD 7700 and not think if these are from Ryzen 5 or 7. In other news, the media jumps down Chuwi's throat instead of getting down to real reporting. I've seen too many times, "Company X has done blah blah". Instead of Company X is allegedly doing XYZ… Reply
sseemaku What about all the mini-pcs? There are so many out there with 7430 CPUs. Are they genuine? Reply
suryasans Most of downcored AMD CPUs for yields are bonus CPUs from AMD. Some manufacturers resold their bonuses to third parties for cheap. The third parties want to clear all cheap CPU inventories by mislabelling or faking their stocks and selling those to any PC OEM company by conspiring with individuals with position in higher level management.
