PowerPC is a type of microprocessor architecture developed in the early 1990s by the Apple, IBM, and Motorola alliance, known as the AIM alliance. It was designed to provide high performance and efficiency for a variety of computing applications, including personal computers, servers, and embedded systems. The PowerPC architecture is based on a reduced instruction set computing (RISC) design, which simplifies the instructions that the processor must execute. This allows for faster processing speeds and better energy efficiency compared to other architectures. Over the years, PowerPC has been used in various devices, including gaming consoles like the Nintendo GameCube and Microsoft Xbox.
