Notebookcheck: CPU-Betrug, nächste Runde: Auch Chuwi CoreBook Plus mit angeblichem AMD Ryzen 5 7430U betroffen

Intro to the article:

> Having only recently confirmed that the Chuwi CoreBook X, contrary to all indications – including information on official Chuwi websites, product data sheets, store websites, the packaging of the device, stickers on the laptop, the Windows system tools and analysis software as well as in the BIOS of the device itself – only has a Ryzen 5 5500U CPU instead of the advertised AMD Ryzen 5 7430U (the exact differences later), this case is now developing into a mid-scale disaster for the manufacturer.

> 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. In addition to the CoreBook X in question, we also found the CoreBook Plus in Chuwi’s range, which is advertised with a Ryzen 5 7430U processor. For this reason, we bought a spot-check unit from a German retailer and also examined this notebook.

> The first results of our test are now available and are disappointing: The Chuwi CoreBook Plus also only has a Ryzen 5 5500U installed, although here – as with the CoreBook X – the use of the Ryzen 5 7430U is actively advertised. Once again, all the information provided by the manufacturer and on the device conceals this fact and makes the CPU appear to the user as a modern 7430U.

On a related note, this article discussed the 1990-2000’s of fraudulent motherboards, such as fake cache and fake chipsets: https://redhill.net.au/b/b-bad.php

> The really silly thing about the fake cache boards was that they actually worked reasonably well some of the time. Not very fast and usually not for very long, but they went OK with a DX-66 or DX-100 CPU. They tended to have a lot of niggle problems—occasional GPFs, traps and hangs, inability to run certain programs, and they were absolutely hopeless as soon as you pushed the bus above 33MHz—so a DX-80, for example, was out of the question. But of course, by removing the cache RAM and crippling the performance, they had also removed one of the most common problem areas in a mainboard. With no cache issues to worry about, a board has to be really bad to give you problems. These, in other words, were really bad.

> „They have an imitation „VX Pro“ chipset, which gives considerably slower performance than a real Intel 430 VX chipset. How slow? ZD Winbench 97 shows at least 10% slower CPU Marks, 16% slower Disk Win Marks (using latest bus mastering drivers for both boards), and 23% slower CD-ROM and video playback performance, compared to VX chipset boards.“
