List of Intel x86 Families

The following is a list of the Intel x86 processor families by year of creation:

x86-16

• (1978) 8086
• (1982) 80286

x86-32

• (1985) 80386
• (1989) 80486
• (1993) Pentium

• (1997) Pentium II
• (1999) Pentium III
• (2000) Pentium 4
• (2003) Pentium M
• (2006) Core

x86-64

Starting with Intel Core 2, Intel started releasing processors with different tradeoffs between wattage and performance, to better support mobile and desktop devices. Presumably the x86 architectures order from lowest-wattage to highest-performance was denoted with the following brands: Atom, Celeron, Pentium, i3,i5,i7, Xeon, and i9, where atom was the lowest-wattage/lowest-performance and i9 was the highest-performance/highest-power CPU. Initially, the i-nomenclature included both desktop and mobile versions, but later the mobile CPUs were renamed using m-nomenclature: m3, m5, and m7 making the lineup: m3, m5, m7, Atom, Celeron, Pentium, i3, i5, i7, Xeon, i9.
