Intel 805xx product codes
Intel discontinued the use of part numbers such as 80486 in the marketing of mainstream x86-architecture microprocessors with the introduction of the Pentium brand in 1993. However, numerical codes, in the 805xx range, continued to be assigned to these processors for internal and part numbering uses. The following is a list of such product codes in numerical order:
