AMD PSP is NOT the same as Intel ME. AMD PSP is a "trusted execution environment" (the first sentence in your link). Intel's equivalent is Intel SGX. Trusted execution environments are a security feature that does not offer remote management. It's not a privacy concern like Intel ME is.

Thank you for clarifying this, all of the acronyms are difficult to reason about if you don't work with them every day.

The PSP is a lot slimmer than Intel ME. It also doesn't randomly yank traffic for specific ports from your Ethernet.

I havent looked at the presentation yet, but are you saying the PSP, like intels ME could be doing nefarious things since its proprietary and closed? Do you have a link to information on the network capturing thing? I mean is that really a thing?

I have heard of these things before but I am not quite sure what the possibilities are. Do you have a link that can summarize what this actual means in terms of security concerns?

CVE-2017-5689

How do you know there isn't an undiscovered CVE for AMD? There's probably maybe 10x more security research focused on Intel

I don't, but they do a lot less with the PSP, especially if you're just using Ryzen Pro and not server SKUs. Intel put a web interface you can't disable with an offbrand networking gear level RCE vulnerability that needs nothing more than ethernet access into their security chip. I don't think AMD can exceed that anytime soon.

Any good link with the details?

There was a good talk with an overview (as well as owning it) at 36c3.
