If you run benchmarks using 32 bit software you will find that most programs run about twice as fast as a 286 on a 386, about 30% faster on an SX. The SX is also slower (at the rated 16MHz speed) than a 16 or 20MHz 286. I would say the SX is a bad deal. It is not as fast at DOS as a 286, or as fast for UNIX or OS/386 as a real 386. It is slightly cheaper than a 386 (and that's probably a marketing decision, I bet it costs more to build) and not as good as either the 386DX or 286 in terms of price/performance. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
