Motorola PowerPC 604

The PowerPC 604 was introduced in December 1994 alongside the 603 and was designed as a high-performance chip for workstations and entry-level servers and as such had support for symmetric multiprocessing in hardware. The 604 was used extensively in Apple's high-end systems and was also used in Macintosh clones, IBM's low-end RS/6000 servers and workstations, Amiga accelerator boards, and as an embedded CPU for telecom applications.
