Chuwi Accused of CPU Specification Fraud in CoreBook X and CoreBook Plus Laptops
Purchasing a new laptop should be a straightforward experience, especially when it comes to receiving the hardware specifications advertised by the manufacturer. However, recent findings suggest that buyers of certain Chuwi laptops may not be getting what they paid for. An in-depth investigation by Notebookcheck has revealed that Chuwi, a well-known Chinese electronics manufacturer, has been shipping laptops with different CPUs than those listed in their official specifications.
Discrepancy Between Advertised and Actual CPU Models
According to Notebookcheck’s review, both the Chuwi CoreBook X and CoreBook Plus were advertised as featuring the AMD Ryzen 5 7430U processor. This particular CPU is based on AMD’s "Zen 3" microarchitecture and is paired with Radeon "Vega 6" integrated graphics, offering users modern performance and efficiency. However, upon closer inspection, it was discovered that these laptops actually contain the older AMD Ryzen 5 5500U processor, which utilizes the previous-generation "Zen 2" architecture and Radeon Graphics 448SP.
The discrepancy was not limited to marketing materials. Chuwi reportedly went as far as modifying the BIOS to display the newer Ryzen 5 7430U as the installed processor. This BIOS alteration caused software diagnostic tools to report the advertised CPU, effectively concealing the true hardware from unsuspecting users. The packaging, laptop stickers, and official website all reinforced the misleading information.
How the Issue Was Uncovered
Notebookcheck’s investigation began when the performance of the CoreBook X review unit did not align with expectations for a Ryzen 5 7430U-powered device. Initially, the reviewers suspected that single-channel RAM might be responsible for the underwhelming results. However, after opening the laptop and examining the processor directly, they identified the part number 100-000000375, confirming the presence of the Ryzen 5 5500U. Further analysis revealed differences in specifications such as L3 cache size, which further distinguished the two CPUs.
This issue was not isolated to a single unit. A separate review of the CoreBook Plus revealed the same substitution, with both models shipping with the older Ryzen 5 5500U instead of the advertised Ryzen 5 7430U. Performance benchmarks and hardware identification tools confirmed the mismatch, despite the BIOS and software reporting otherwise.
Chuwi’s Response and Ongoing Developments
When confronted with these findings, Chuwi reportedly attributed the issue to a production error. However, the company also threatened legal action against Notebookcheck for alleged brand damage and requested the removal of the investigative article. Notebookcheck declined to comply, maintaining the integrity of their reporting. As of now, Chuwi has not issued a public statement addressing the repeated discovery of this issue in multiple laptop models.
This situation raises significant concerns about transparency and trust in the consumer electronics market. Buyers are encouraged to verify hardware specifications independently, especially when purchasing from lesser-known brands. The ongoing investigation highlights the importance of third-party reviews and the need for manufacturers to uphold honest marketing practices.
