The PSP is not the same as SGX. That's more like the management engine, and while I agree that both Intel and AMD are shipping that antiuser "feautue" and that AMD had its own implementation of a trusted execution environment like SGX, the current AMD chips do not ship with it. AMD is not perfect, but it's sad that people can choose one or the other and still prefer to hand Intel their money when Intel goes out of their way to take advantage of their users.

- Intel wanted to lock users to RamBus RDRAM which was incompatible with AMD chips and a patented technology which AMD would not be able to use.

- Intel shipped the aforemtioned CPU identifier. Intel did the management engine first.

- Intel locks its chips from frequency tuning so they can charge more for overclocking.

- Intel locks the amount of RAM that is addressable by their chips arbitrarily rather than basing it on hardware support in order to squeeze more money out of you.

- Intel and NVIDIA locked their GPU linking technology (SLI) while AMD allows Crossfire to run on both Intel and AMD processors.

These are just the ones I remember off the top of my head. Not all of them may be current, but it's obvious that Intel has no problem extorting money from their customers in a million ways where AMD doesn't play this disgusting game.

As far as I can tell, AMD does currently ship a trusted execution environment supporting remote attestation, namely SEV. However, it’s only supported on server-class processors, so it’s unlikely to be used for DRM.

But AMD is fully on-board of the Microsoft Pluton platform, while even Intel is not. So again, the only difference was that AMD didn't have the means for these types of schemes. Now they do and they are also growing in the enterprise/datacenter market, so they will inevitably build more and more of this.

Are you sure about that? Ten years ago or so I had an ASUS motherboard for AMD processors that explicitly supported SLI.

- Intel disables ECC Ram support for their consumer CPUs, AMD does not
