I would have guessed that the 8088 is much faster at aboutthe same clock speed, because it has more 16-bit operationsand does multiplication and division in hardware. Of coursethe compiler back ends also play a role, but the Z80 backendtypically emits *more* instructions for the same program. In case you have,what was your experience? Any technical explanation for myresults? > I would have guessed that the 8088 is much faster at about> the same clock speed, because it has more 16-bit operations> and does multiplication and division in hardware.

The 8088 gives up a substantial portion of any 16-bit advantage to its8-bit external bus. > The 8088 gives up a substantial portion of any 16-bit advantage to its> 8-bit external bus.
