A supposed bargain is currently causing considerable discussion: The Chuwi CoreBook X, which is officially advertised with an AMD Ryzen 5 7430U, has an older Ryzen 5 5500U installed. This not only raises the question of performance, but above all the trust in the manufacturer's product specifications.
Honestly, we know where the root of this problem came from. Back in the 1990s Intel broke with convention of using ever increasing numeric model numbers
Intel didn’t like that other CPU manufacturers of x86 CPUs (AMD, Cyrix, IBM) could use the same numbering scheme. So Intel created “Pentium” because it could be copyrighted/trademarked so other companies couldn’t use it.
