To the best of my knowledge, there are 2 differences.  One is the strain of
yeast.  Some are more vigorous than others, and just about every yeast
manufacturer has it's own, which is why you'll find that the "same" yeast
from different companies will act differently.  Next is the process by which
the yeast is deactivated, to keep it dormant till you wake it up when
_you're_ ready for it to work.  The process often used is a heat drying
process.  This does, however, kill off some of the yeast.  Instant yeast is
dried at lower temps than active dry, killing fewer yeasties in the process,
so you get a faster start, and generally more bang for your buck.

Not Adamantius, nor Bear, but a baking freak, nevertheless.
