Additional Details:

The NG80386SX-16 utilized a 16-bit external data bus to reduce the complexity and cost of motherboard designs, making it a popular choice for entry-level 32-bit systems. It supported a maximum of 16MB of physical memory. This processor paved the way for more advanced 32-bit processors and played a significant role in the transition from 16-bit to 32-bit computing. The NG80386SX-16 was typically paired with a math coprocessor (like the 80387SX) for improved floating-point performance.
