The real difference is: a 386 SX has a 24 bit address path and a 16 bit data path. This allows it to address 24 MB and plug into existing '286-like' boards. Its I/O is very similar if not identical to the 286. The 386 DX of course has a 32 bit address and 32 bit data path. This gives addressability over 4 GB of memory. The speed differences between a 386 DX and 386 SX at the same frequency are all attributable to the multiple memory and I/O bus accesses.
