Versus the competition? Modern x86 and ARM chipsets are not only proprietary from the ISA-up, they have the same proprietary extensions.

"RISC chipset adds in proprietary CISC features" has been in my headlines so often that I assumed nobody cared. Helluva time to go up-in-arms, in Q3 2025.



In the end a small distinction that hardly matters when buying OEM boards.


Obviously. But that has nothing to do with what your comment said.


Usually those boards come with RISC-V CPUs using proprietary extensions, for dismay of RISC-V FOSS advocates, it has everything to do with it.


Well then you probably should have said "RISC-V isn't entirely open" rather than "as open" because now your responses make nearly no sense.
