AMD also has a form of the Intel Management Engine (IME). AMD calls theirs the Platform Security Processor (PSP) also known as AMD Secure Technology. Much like Intel's solution, it is a complete system entirely isolated within the physical CPU chip.

The Intel Management Engine stuff goes back a little further than i3/i5/i7 era chips putting it about 2007-2008.

AMD had publicly started to put their "security" solution into their chips around the bulldozer era of chips 2011-2012.

Also, modern motherboards use UEFI bios which is just as worrying as all the stuff in the CPU chips.
