WebOne advantage of inclusive cache is its snoop filtering capability, i.e., external snoops from another sockets or chipset do not require L2 lookup if a miss occurs in L3. WebAnother advantage of inclusive caches is that the larger cache can use larger cache lines, which reduces the size of the secondary cache tags. (Exclusive caches require both caches to have the same size cache lines, so that cache lines can be swapped on a L1 miss, L2 hit). If the secondary cache is an order of magnitude larger than the primary ...
