Intel really likes making things exclusive to themselves. 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 enterprise features and advanced security instructions.

They even made their C compiler take advantage of advanced processor features only with their own CPUs, which translated to a very noticeable difference in performance between Intel and AMD chipd, 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.
