Independent testing has recently uncovered what it describes as a potential CPU mislabeling issue affecting multiple Chuwi laptops. In its latest report, Notebookcheck found that the Chuwi CoreBook Plus, which is marketed as using an AMD Ryzen 5 7430U, actually shipped with the older Ryzen 5 5500U processor instead.
What makes the situation more unusual is that the laptop’s packaging, product pages, BIOS, and even Windows system tools reportedly identify the chip as a Ryzen 5 7430U, making it difficult for buyers to detect the discrepancy without deeper inspection. The discovery has raised concerns about transparency in the budget laptop market, especially since this isn’t the first time such a mismatch has been reported.
What exactly is the CPU controversy about?
According to Notebookcheck’s investigation, the CoreBook Plus is actively marketed with the Ryzen 5 7430U, a newer Zen 3 processor launched in 2023. However, after purchasing and opening a retail unit, the reviewers discovered the laptop actually contained the Ryzen 5 5500U, an older Zen 2 chip released in 2021.
The difference may not sound huge on paper, but the newer processor has a higher boost clock and double the L3 cache (16 MB vs 8 MB), which can translate to better performance in certain workloads. In other words, buyers may believe they are getting a newer chip typically found in laptops priced €100–€200 higher, potentially making the system appear like a better bargain than it actually is. Even more surprising is the fact that the laptop’s firmware and software identifiers were configured so that system utilities still report the CPU as a Ryzen 5 7430U, masking the true hardware unless the device is physically opened.
Is this an isolated case or something bigger?
Unfortunately, the CoreBook Plus may not be the only device involved. Earlier testing found a similar issue with another model, the Chuwi CoreBook X, which was also advertised with a Ryzen 5 7430U but reportedly shipped with the same Ryzen 5 5500U chip instead. With two separate laptop models showing the same mismatch, investigators say the issue appears unlikely to be a simple labeling mistake.
Chuwi has reportedly responded to inquiries by saying it is investigating the matter internally. However, Notebookcheck says the company also repeatedly asked the publication to take down its earlier reports, warning of potential legal action due to alleged reputational damage, which ultimately prompted the outlet to dig deeper into the issue.
For consumers, the takeaway is fairly simple: always verify specs, the best you can. If a laptop deal looks unusually good, it might be worth taking a closer look.
