Chuwi CoreBook X reportedly ships with Ryzen 5 5500U while advertised as Ryzen 5 7430U
© NotebookCheck Notebookcheck reports that its Chuwi CoreBook X review unit, advertised as shipping with an AMD Ryzen 5 7430U, actually contained a Ryzen 5 5500U. The outlet says the discrepancy was not only present at the hardware level, but also hidden by system reporting so the laptop identifies itself as the newer 7430U in common tools. Worth noting that reviewers did not notice this, and only prompted their check after users report.
To verify the CPU, Notebookcheck opened the laptop, removed the cooler, and read the ordering part number printed on the package. It reports the chip shows OPN “ 100-000000375″ , which AMD lists as Ryzen 5 5500U.

The report also claims the masking happens both in BIOS and within Windows, which reduces the chance an average buyer will notice. Notebookcheck adds that it initially dismissed an L3 cache anomaly during testing, because the expectation is that a new system accurately reports its installed CPU.
On paper, the two processors sit close in core count, but they are not the same part. AMD lists Ryzen 5 7430U as a Zen 3 “Barcelo R” chip with 6 cores and 12 threads, 16 MB L3 cache, and a 15 W default TDP. AMD also lists its tray product ID as 100-000001471.
AMD lists Ryzen 5 5500U as “Lucienne” with 6 cores and 12 threads, up to 4.0 GHz boost, 8 MB L3 cache, PCIe 3.0, and a 15 W default TDP, with tray product ID 100-000000375 and a launch date of January 12, 2021.
As for what the 7430U actually is, it is not a new design. CPU databases like CPU-World describes Ryzen 5 7430U as effectively identical to the older Ryzen 5 5625U, which is part of AMD’s ongoing mobile rebrand cycle. It’s not even a big change, but this doesn’t mean Chuwi should artificially report on the wrong CPU.
