Intel really likes making things exclusive. Especially with the threats to x86 from ARM and RISC-V, I’m worried that it’ll quickly become an Intel CPU only thing. Or worse, an Intel Xeon only thing since it’s industrial/enterprise. They’ve done this with everything from ECC memory support, to Optane acceleration, to booting from special volumes like RAID, to enterprise fleet management features and advanced security instructions, most of which you can only get on Xeon enterprise chips and not Core consumer chips (or, only Intel CPUs in general in the case of Optane drive caching).

They even made their C compiler take advantage of advanced processor features only with their own CPUs, which translated to a definite difference in performance between Intel and AMD chips when running the same binary. Despite AMD CPUs being capable of the same or similar performance tricks, proven by the fact that open source compilers produced similarly performant binaries for all chips.
