CPU scam: Chuwi CoreBook X uses AMD Ryzen 5 5500U instead of 7430U

This is where the core problem of the whole matter becomes apparent. Anyone who does not explicitly expect that a component apart from the one specified could be installed usually does not scrutinize the system information read out in detail. This was also the case in our test. Our test was primarily concerned with the practical impression: How does the notebook perform in everyday use? Are the display quality, SSD performance, connectivity, and battery life right? Does the overall performance correspond to what can be expected in this class?

The basic technical data was tested, but not with the level of suspicion that would have proved necessary in retrospect. An anomaly in the L3 cache was therefore ignored, as it is generally assumed that the CPU is correctly identified in a new device. We noticed that the measured performance was not quite at the expected level of a typical Zen 3 processor. Nevertheless, we suspected the causes were elsewhere. The built-in single-channel RAM was an obvious explanation, as this memory mode has been proven to have a noticeable effect on performance. Only afterward did it become clear that the actual cause is obviously of a much more fundamental nature.

We immediately contacted the manufacturer and asked for a statement. 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. The company no longer has any direct influence on these devices. The manufacturer also admits that this issue is being taken very seriously and that an internal investigation has been initiated to clarify the exact cause. However, this is not a satisfactory answer, especially as customers have been deliberately misled here. All system tools lead the user to believe that they have purchased the newer 7430U - as advertised.
