Legends of the RISC Wars

RISC (Reduced Instruction Set Computer) architecture emerged in the 1970s-80s as an alternative to CISC, promising faster performance through simpler instruction sets. Companies like Sun (SPARC), MIPS, HP (PA-RISC), IBM (PowerPC), and DEC (Alpha) competed intensely through the late 1980s and early 1990s, achieving impressive benchmark numbers. However, RISC's advantages diminished as both architectures adopted superscalar processing, adding complexity to RISC while Intel made x86 more RISC-like internally. Combined with x86's massive software ecosystem and Moore's Law, Intel ultimately won the workstation and server markets by the mid-2000s, though RISC concepts influenced modern processor design and succeeded in mobile computing through ARM.
