If only it was that simple. If you make a quick search, you will notice that even from experts in the field, there's a moment of doubt when it comes to verifying that the RNG is true. Intel and AMD chips come with an RNG that is impossible to verify completely as far as I'm concerned. You cannot distinguish a pseudo-RNG from a true RNG, because you cannot detect if there is a function that deems deterministic the number generation.
Regarding Intel and AMD chips, their RNGs aren't being used to generate the entropy, right? I mean, if I am creating a seed for a software wallet on my computer, I will be using the entropy of my OS, regardless if on Linux or Windows. And if I am working with a hardware wallet, they have their own RNGs inside the device.
When you say that Intel and AMD's RNGs can't be verified, I doubt it's weak and affects seed generation. Otherwise, almost all wallets generated on such chips wouldn't be secure, and we would have many complaints and reports of mysteriously lost coins.
