In 2025 Chuwi released a laptop with a 7430U CPU, however it was found that it actually had a 5500U.

Background

[edit | edit source]

On 2 July 2025, Chuwi, a Chinese company that makes and sells laptops and mini-PCs launched the 'Chuwi CoreBook X 7430U'[1], an addition to its CoreBook X lineup which also featured an Intel model.

Chuwi's false advertisement

[edit | edit source]

On the 4 March 2026, NoteBookCheck who had previously done a review of the CoreBook X 7430U, put out an article warning potential buyers about false advertisement of the product.[2] Chuwi was actually using a 5500U, with software/firmware designed to make it look like a 7430U. In addition some users reported also receiving a SATA SSD[3] instead of the advertised NVME SSD. Reports for the CPU false advertisment go back to at least December of 2025.[4] NoteBookCheck also did a follow up article showing that another Chuwi device, the 'CoreBook Plus' also had the same false advertisement of the CPU.[5]

Chuwi's response

[edit | edit source]

Initially, Chuwi's response to NoteBookCheck wasn't very good the article saying "Chuwi did indeed reply but did not explicitly admit to an error. Instead, it referred to various production batches, or more precisely to remaining stocks still in circulation."[2]. In addition, Chuwi tried to get NoteBookCheck to take down their original article, even threatening legal action. "Repeated requests from Chuwi to take our related articles offline - under threat of legal action due to the reputational damage caused, mind you - have prompted us to investigate further."[5]

After this, AMD put out a statement to Chinese language outlet Sina,[6] which was then translated and widely reported on by English outlets.[citation needed (13 September 2026)] A few days after this, Chuwi put out another statement this time on their blog[7] saying:

Due to a production error, a limited number of CoreBook X and CoreBook Plus units were assembled with incorrect processors. If you have received a device that does not match the specifications you ordered, please return it for a full refund. You may initiate the return through your original purchase channel or contact our official support team at [email protected] for assistance.

However, they also state to "please ensure the device is in original condition with all accessories included" so it's possible that returns could be denied. In addition, the return was only valid until 31 May 2026.
