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.
