I think Intel's ME is much more complex than AMD's PSP. Does anyone know if AMD's PSP has a full network stack and the ability to interact with network hardware independent of the main CPU's OS?

I had read somewhere that AMD PSP does not have Internet access.

  It does, DASH is also arguably much less secure than Intel's RMT.

    Hmm, I did not know this. Good to know!

    Is there a documentation of what its capabilities are? I can't find anything specific about it.

      Of the remote management? Only this https://developer.amd.com/tools-for-dmtf-dash/ https://developer.amd.com/tools-for-dmtf-dash/ AMD hasn't really had any hardware for the enterprise for a long time so they are quite behind on many things. This is their free remote admin tool : https://community.amd.com/community/devgurus/dmtf-dash/blog/2017/06/08/amc-25-amd-management-console-release-announcement https://community.amd.com/community/devgurus/dmtf-dash/blog/... It can basically do quite a few things, change firmware, boot an image, redirect USB input and likely quite a few of other undocumented things. With Ryzen Pro launching soon I guess AMD would release a new suite of remote management software.

Yes, AMD's PSP runs a full OS which was made by Trustonic.

  Trustonic is about as trustworthy a name as "Safecorp" or something similar. The name itself is just one big red flag.

    They are probably the largest TEE* supplier AFIK even bigger than Intel; they are pretty much the Java of the TEE world. It’s a joint venture between ARM, Gemalto and a few other companies iirc. *Trusted Execution Environment

      Ahhh, okay. Thanks for the clarification!

  It must feel weird to create an operating system that runs on a CPU inside a bigger CPU.

    Technically if you count virtual machines as CPUs then every piece of Javascript etc. code runs in a CPU inside a CPU :P
