All the RISC architectures had superior performance over x86-32 in the '90s.
MIPS is much larger than SGI, and POWER [1] is much larger than PPC (or Apple). MIPS and POWER have been used in consoles, for example. That is volume! Especially MIPS, is used in embedded chips (together with predominantly ARM). Those are found on every mainboard, laptop, console even though the latest gen consoles run on AMD64.
Alpha however, died somewhere within DEC/Compaq/HP.
My friend argued the NSA was using Alpha processors internally, and had their own fab. I have no clue about that though.
