It also permits the use of cheap 8080-family ICs, where the 8254 CTC, [[Intel 8255|8255]] PIO, and 8259 PIC were used in the IBM PC design. In addition, it makes PCB layout simpler and boards cheaper, as well as demanding fewer (1- or 4-bit wide) DRAM chips.</ref> and is notable as the processor used in the original [[IBM Personal Computer|IBM PC]] design.

The 8086 gave rise to the [[x86]] architecture, which eventually became Intel's most successful line of processors. On June 5, 2018, Intel released a limited-edition CPU celebrating the 40th anniversary of the Intel 8086, called the [[Coffee Lake|Intel Core i7-8086K]].<ref name="Intel"/>
