The argument is that :

" The Z-100 is faster than the AT because the AT requires that one wait state
  on its memory cycle and the Z-100 doesn't."

Now both Z-100 and AT use 150ns RAMS.  Why did the AT designers have to
insert that 1 wait state?  The reason is that the 80286 was just too fast
for those 150ns RAMS.  If the claim is that an 8088 running at 8 Mhz is
faster than a 6 Mhz 80286 then it too must have that 1 wait state.  If it
doesn't need 1 wait state, then it must obviously be slower than the 80286.
