Most important CPU's Chronological Order:
1) Intel 4004 (1971) - The first commercially viable cpu.
2) Intel 8088 (1972) - The Grandfather of the modern PC CPU.
3) Motorola MC6800 (1974) - Grandfather of the MC68000 series.
4) Zilog Z80 (1976) - Z80 instruction set, used in the Radio Shack TRS-80.
5) MC68000 (1979) - The first of the incredible Motorola 68xxx series of processors.
6) 80186 (1981) - The first x86 compatible chip.
7) 80286 (1982) - The CPU used in the IBM PC-AT. Introduces protected mode.
8) Motorola MC68020 (1984) - The first 32 bit microprocessor.
9) R2000 (1985) - First MIPS processor.
10) 80386 (1986) - 32 bit cpu for Intel. Introduces virtual mode (one or more real mode programs can be run in a protected environment) 4GB flat memory model. Also paging translation for simpler virtual memory management.
11) SPARC v7 (1986) - The CPU that makes Sun Microsystems a major technology player for years to come.
12) 80486 (1989) - dominates the CPU market for years which is eons in technological terms.
13) IBM RS6000 (1990) - This CPU was the predecessor to IBM's PowerPC line.
14) AMD Am386 (1991) - Marks AMD's first foray into direct competition with Intel. 386 Clone.
15) Pentium (1993) - Intel's first superscalar (more than one instruction per clock cycle), 64 bit data bus.
16) Pentium Pro (1995) - Introduces on-package L2 cache, new micro architecture.
