In my experience, running MS-DOS an SX is equally fast as a full 386. I
think that is because MS-DOS is a 16-bit system, and runs in 16 bit real
mode of 386's. Therefore there is no speed advantage from the 32 bit
bus. I may be wrong, and I'm sure someone will correct me if I am.

The SX can address 16 Mb of RAM vs. the full 386's 4gigabytes.
