Centaur measured the most frequently used instructions used by
Windows, and optimised the CPU for those.  Or at least that
was the theory.  Performance-wise, it didn't really change the
world, as the AMD K6 was around at pretty much the same time
which wiped the floor with it, whilst only being slightly
more expensive.
