Chuwi - 7430U product false advertisement

Chuwi advertised its CoreBook X 7430U laptop with an AMD Ryzen 5 7430U processor in 2025. In March 2026, Notebookcheck reported finding an older Ryzen 5 5500U in its test unit despite the software identifying it as a 7430U. The publication subsequently found the same discrepancy in a retailer-purchased CoreBook Plus.

Background

Chuwi's launch announcement on 2 July 2025 advertised the CoreBook X 7430U with a Ryzen 5 7430U processor and a 512 GB PCI Express (PCIe) solid-state drive (SSD).

Processor specification discrepancy

On 4 March 2026, Notebookcheck reported that removing the CoreBook X test unit's cooler revealed the processor marking 100-000000375, identifying a Ryzen 5 5500U. The publication said the firmware setup interface (BIOS) and Windows instead identified the processor as a Ryzen 5 7430U.

On 12 March, Notebookcheck reported the same finding in a CoreBook Plus it had purchased from a German retailer. It contrasted the older processor's Zen 2 architecture and 8 MB level-three cache with the advertised 7430U's Zen 3 architecture and 16 MB cache. The findings concerned the units inspected, rather than a verified count of all affected devices.

Company responses

Notebookcheck said Chuwi initially referred to production batches and remaining stock, and said it was investigating, without explicitly admitting an error. In its follow-up report, the publication said Chuwi had requested removal of the coverage under threat of legal action.

AMD denied authorizing or participating in the mislabeling, according to a translated statement reproduced by OC3D on 18 March 2026. AMD also reserved the right to pursue legal action.

In a statement dated 23 March 2026, Chuwi attributed the incorrect processors to "a production error" affecting "a limited number" of CoreBook X and CoreBook Plus units. It offered a full refund through the original purchase channel or its support team. The published return guidelines required the device to be in its original condition with all accessories and set a deadline of 31 May 2026.

Consumer response

In a 24 January 2026 Linus Tech Tips forum post, purchaser adsta reported receiving a Serial ATA (SATA) SSD rather than the advertised PCIe drive and noticing that the processor had less cache than expected. The purchaser said support required them to pay return costs and had not addressed the specification complaints. They reported initiating a credit-card charge-back and said the experience had lost Chuwi a customer. The post did not establish the outcome of the charge-back.
