The Intel 80386 is a 32-bit microprocessor containing over 275,000 transistors on a single chip. The 80386 (commonly known as the "386 chip") could handle four million operations per second and handle memory up to four gigabytes (4,294,967,296). The 386 was ... compatible with Intel's earlier processor line for the IBM PC and compatibles and could run software designed for those processors as well. The 386 chip brought desktop personal computing power to a new level. John Crawford was the architecture manager for the Intel 386 and the Intel 486 microprocessors, and co-manager of Pentium microprocessor development.
