KembaraXtra–Computer Terms – 386SX
386SX refers to a cost-reduced version of the Intel 80386 microprocessor. While it retains a 32-bit internal architecture and instruction set, it uses a 16-bit external data bus and often a narrower address bus. This made it cheaper to integrate into computer systems, as it could be paired with less expensive support chips and memory subsystems. As a result, 386SX-based systems offered many of the programming advantages of 32-bit processors at a lower overall cost, although with somewhat reduced performance compared to 386DX systems.
