The x86 architecture is almost 50 years old. Intel 8086 processor was introduced on June 8, 1978

The Intel 8086 processor influenced the computer industry, laying the foundation for the x86 architecture, which is still used in most computers today. Introduced on June 8, 1978, this processor ushered in Intel’s era of dominance in the microprocessor world.

Developed by a team led by Stephen Morse, the Intel 8086 appeared in tough competition from Motorola, whose 6800 processor was very popular. Unlike the 6800, which used a flat address space, the 8086 used segmented memory addressing, which allowed for more powerful and versatile computing devices. This processor launched a whole line of chips, including the 80286, 80386, 80486, and the legendary Pentium series, which replaced the 80486.

One of the most significant aspects of the 8086’s legacy is its instruction set architecture (ISA), which has been maintained and expanded over the decades. In recognition of its importance, in 2018, the fortieth anniversary of the 8086, Intel released the Core i7-8086K processor, emphasizing the continuation of its legacy in modern technology.
