Explanation
In a cache-independent system, different system components have a close
match. No particular system component strongly limits the
system performance. The processor speed matches closely with
the memory bandwidth, interconnection network (if present) and
input-output system. In the above graph, there is a significant dip
in the QUIPS for unbalanced system during the memory level change
(primary cache to secondary cache, secondary cache to main memory).
In contrast, for the cache-dependent system, the dip in the curve
(from primary cache to main memory) is not significant. It suggests
that performance will not drop significantly once the application
size is increased from primary cache to main memory.
