The PowerPC 604e was the first Mac processor available in a symmetric multiprocessing (SMP) configuration. The PowerPC 601 was the first Mac processor to support the 32-bit PowerPC instruction set architecture.Ī Motorola PowerPC 603 processor Processor The MC68LC040 version was less expensive because it omitted the floating-point unit. ![]() The Motorola 68040 had 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. Another improvement over the 68020 was the addition of a data cache. The Motorola 68030 was the first Mac processor with an integrated memory management unit, allowing for virtual memory. It had 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 Apple MacBook 'Core 2 Duo' 2.0 13-Inch (White - Mid-2007) features a 2.0 GHz Intel 'Core 2 Duo' processor (T7200), with two independent processor 'cores' on a single silicon chip, a 4 MB shared 'on chip' level 2 cache, a 667 MHz frontside bus, 1 GB of 667 MHz DDR2 SDRAM (PC2-5300) installed in pairs (two 512 MB modules), an 80.0 GB Serial. The Motorola 68000 was the first Apple Macintosh processor. A Motorola 68000 processor in a dual in-line package, as the early Macintosh models used
