386sx is a pure 16 bit version of the 386. 100% compatible software-wise,
ie. supports all 386 instructions.  However, the 16 bit bus means at least 
twice as slow (for same MHz) in all I/O including memory read/write.
Fastest version available is 16 MHz (or may be there are some 20 MHz ones).
Whereas the 386 can run from 16 MHz to 33 MHz.

This is generally not correct. In most situation, a 286 machine will run
faster than a 386sx machine (at same MHz). But 386sx can run 386 specific
software.

So, the 386sx is a dead end in speed but has a bright future in term of
software compatibility now that we are seeing more and more 386 specific
programs coming out.
