Motorola 68020

Thumb
A Motorola 68020 processor

The Motorola 68020 was the first 32-bit Mac processor, first used on the Macintosh II. 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 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).

A Motorola 68030 processor

The Motorola 68030 was the first Mac processor with an integrated paged memory management unit, allowing for virtual memory. Another improvement over the 68020 was the addition of a data cache.

Motorola 68040

Thumb
A Motorola 68040 processor

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.

The MC68LC040 version was less expensive because it omitted the floating-point unit.

M1

Thumb
An Apple M1 processor

The M1 is a system on a chip fabricated by TSMC on the 5 nm process and contains 16 billion transistors. Its CPU cores are the first to be used in a Mac processor designed by Apple and the first to use the ARM instruction set architecture. It has 8 CPU cores (4 performance and 4 efficiency), up to 8 GPU cores, and a 16-core Neural Engine, as well as LPDDR4X memory with a bandwidth of 68 GB/s. The M1 Pro and M1 Max SoCs are fabricated by TSMC on the 5 nm process and contain 33.7 and 57 billion transistors respectively. Both have 10 CPU cores (8 performance and 2 efficiency) and a 16-core Neural Engine.

The M1 Pro and M1 Max have a 16-core and 32-core GPU, and a 256-bit and 512-bit LPDDR5 memory bus supporting 200 and 400 GB/s bandwidth respectively.[20] Both chips were first introduced in the MacBook Pro in October 2021.[21]

The M1 Ultra is a processor combining two M1 Max chips in one package.[22] It was available exclusively in the highest-end variants of the Mac Studio, released on March 18, 2022. All parameters of the M1 Max processors are doubled in M1 Ultra processors, as they are essentially two M1 Max chips operating in parallel; they are, however, packed as one processor package (in size being bigger than Socket AM4 AMD Ryzen processor)[22] and seen as one M1 Ultra processor in macOS.
