2011 macbook pro geekbench 412/1/2023 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.
