three. The latest PC designs with high-end memory or aggressive caching might be able to operate with no (zero) wait states.
As you might imagine, await state is basically a waste of time, so more wait states result in lower system performance. Zero wait states allow optimum system performance. Table 23-9 illustrates the general relationship between
CPUs,
wait states, and memory speed. It is interesting to note that some of the fastest systems allow the most wait states. This flexibility lets the system support old, slow memory,
