Security | Intel vs Amd

are there AMD, with non-AMD PSP processors ?

do we need me_cleaner after using AMD ?

can we ensure that, AMD with non-AMD PSP processors, contain no backdoor ?

Related to my issue , i have just checked BIOS and the Intel sticker, actually I don’t find any vPro, usually the Intel vPro will be written at the Intel sticker logo on Laptop. So the assumed backdoor exists without vPro.
