IBM Power Chips/PowerPC - Moore's Law In Pictures
ARM wasn’t the only processor type to be developed out of the nascent RISC architecture. IBM had been toying with RISC since the 1970s, and the company became known for a powerful CPU called the 801. By 1990 IBM’s RS/6000 workstation and server computers ran multi-chip Power microprocessors (Performance Optimized With Enhanced RISC), and two years later there were single-chip versions. The Power line (through seven iterations, as well as PowerPC) continued, and Apple helped make a name for the IBM microprocessor architecture within its own product branding scheme (PowerBook, etc.).
