![]() ![]() PowerPC 604 An IBM PowerPC 604e processor PowerPC 603 A Motorola PowerPC 603 processor Processor The PowerPC 601 was the first Mac processor to support the 32-bit PowerPC instruction set architecture. PowerPC PowerPC 601 An IBM PowerPC 601 processor The MC68LC040 version was less expensive because it omitted the floating-point unit. The Motorola 68040 has improved per-clock performance compared to the 68030, as well as larger instruction and data caches, and was the first Mac processor with an integrated floating-point unit. Motorola 68040 A Motorola 68040 processor ![]() Another improvement over the 68020 was the addition of a data cache. The Motorola 68030 was the first Mac processor with an integrated paged memory management unit, allowing for virtual memory. Motorola 68030 A Motorola 68030 processor The Macintosh LC configured the 68020 to use a 16-bit system bus with ASICs that limited RAM to 10 MB (as opposed to the 32-bit limit of 4 GB). The 68020 has many improvements over the 68000, including an instruction cache, and was the first Mac processor to support a paged memory management unit, the Motorola 68851. The Motorola 68020 was the first 32-bit Mac processor, first used on the Macintosh II. Motorola 68020 A Motorola 68020 processor It has 32-bit CPU registers, a 24-bit address bus, and a 16-bit data path Motorola referred to it as a "16-/32-bit microprocessor." Processor The Motorola 68000 was the first Apple Macintosh processor. Motorola 68k Motorola 68000 A Motorola 68000 processor in a dual in-line package, as the early Macintosh models used It is grouped by processor family, processor model, and then chronologically by Mac models. ![]() This list of Mac models grouped by CPU type contains all central processing units (CPUs) used by Apple Inc. ![]()
