The most important thing for me. Zen cores have the AMD equivalent of Intel AMT ? (I don't remember the name).

If it haves it, I would avoid it like a pest, and get an FX-8370 or 8350 to replace my now aging FX-4100. The last thing that I like to have on my computer is a hidden uncontrollable CPU doing things that could affect to my privacy.

Unfortunately, it seems impossible to acquire a modern x86/x64 chip without such hidden firmware. The last Intel CPUs without it are from 2008, and the last AMD CPUs without it are from 2013.

If you can tolerate using a different CPU architecture, Raptor Engineering's Talos Secure Workstation looks very intriguing. https://www.raptorengineering.com/TALOS/prerelease.php

and those have cpu wide ring0 escalation bug https://www.blackhat.com/docs/us-15/materials/us-15-Domas-Th...

Why is the power8 architecture not more widely used? The performance is competitive with the intel's Xeon series and for memory or IO bound workloads a power8 CPU is often superior.
What you talking about is Platform Security Processor (PSP) and according to libreboot website it's built in all their CPUs released since 2013.
Libreboot is inaccurate on this one, as far as I can tell this is only on the Puma chips right now, but it's likely it will make it's way to other chips as they come out. Newer Bulldozer-derived (Family 15h) cores made today such as the current FX lineup do not have the PSP.
So, I'm going to grab an FX8350
Get the 8320e at Microcenter for $90 and over clock it. It'll be faster and cheaper.
AMD has the Platform Security Processor in the Puma chips (Mullins and Beema) which serves the same purpose as the Intel ME (Management Engine). I would not be surprised if this made its way into Zen.
