For Silicon Graphics, the Iris 4D series marked a shift from Motorola microprocessors to RISC ("reduced instruction set computing") processors built by MIPS Technologies, Inc. Five years later, in 1992, SGI acquired MIPS for $333M. But in 1998 it abandoned MIPS processors in favor of Intel’s Itanium.
