Of course it does; at least twice as fast. This is because the '286 accesses memory 16 bits at a time (fetch), as opposed to 8 bits at a time (fetch fetch). A '386 (not an sx) will access a full 32 bits at a time (FETCH!), and so if it runs at the same clock rate it will be roughly twice as fast again. Of course, if you take advantage of the enhanced instruction set, you can get even greater speedup. In the rare case that original ideas Kenneth J. Hendrickson N8DGN are found here, I am responsible.
