Budget-friendly laptop manufacturer Chuwi is again facing scrutiny after reports surfaced indicating the company shipped devices with processors different from those advertised. This follows a previous investigation revealing a similar issue with the CoreBook X model, and now extends to the CoreBook Plus, raising concerns about transparency and product specifications.
The latest findings, reported by Notebookcheck, suggest that Chuwi advertised both the CoreBook X and CoreBook Plus as featuring the AMD Ryzen 5 7430U processor. However, testing revealed that both laptops were equipped with the older AMD Ryzen 5 5500U. This discrepancy impacts performance, as the Ryzen 5 7430U utilizes the newer “Zen 3” architecture, even as the 5500U is based on the “Zen 2” architecture.
CPU Discrepancy and Firmware Manipulation
The issue isn’t simply a matter of using an older processor; Chuwi allegedly went to lengths to conceal the substitution. According to TechPowerUp, the company modified the BIOS to report the Ryzen 5 7430U to the operating system and diagnostic tools like CPU-Z and HWiNFO64. This manipulation misled users and reviewers attempting to verify the laptop’s specifications.
Notebookcheck’s initial investigation into the CoreBook X revealed lackluster performance, prompting a deeper look that uncovered the use of the Ryzen 5 5500U. Further examination showed differences in L3 cache size and other specifications confirming the processor swap. The company has yet to provide a satisfactory explanation for the discrepancy, leading to criticism and calls for greater accountability.
Impact on Consumers and Previous Concerns
This isn’t an isolated incident. Notebookcheck’s review of the CoreBook X initially highlighted the laptop’s affordability and 2K display, but the discovery of the incorrect processor led to the deactivation of the device’s rating. The practice raises questions about the accuracy of marketing materials and the potential for misleading consumers seeking specific hardware configurations.
Tom’s Hardware reports that Chuwi vaguely referenced different production batches and leftover stock as a possible explanation, a response many found unconvincing. Users on Reddit had previously voiced concerns about the CoreBook X’s performance, contributing to the investigation.
Broader Implications and Ongoing Investigation
The CPU substitution impacts graphics performance, as the Ryzen 5 5500U features Radeon Graphics 448SP, while the advertised Ryzen 5 7430U includes Radeon “Vega 6” graphics. While the CoreBook X and Plus are marketed towards students, office workers, and general users, the performance difference could be significant for those requiring more graphical processing power.
The situation highlights the challenges consumers face when purchasing from lesser-known brands, particularly those offering significantly lower prices than established competitors. The practice of misrepresenting hardware specifications erodes trust and raises concerns about quality control. Videocardz notes that What we have is the second instance of this issue being discovered within Chuwi’s product line.
Chuwi has stated it is conducting an internal investigation, but as of March 14, 2026, has not issued a comprehensive statement addressing the allegations or offering remedies to affected customers. The outcome of this investigation and any potential corrective actions will be crucial in restoring consumer confidence.
What comes next will depend on the results of Chuwi’s internal investigation and whether any regulatory bodies take action. Consumers considering Chuwi products should exercise caution and independently verify specifications before making a purchase.
