Exclusive cache hierarchy as used on AMD processors is an effective solution to allow processor cores to have a large private cache while still benefitting from shared cache. The shared cache stores the "victims" (i.e., data evicted from private caches). The performance depends on how victims of co-run programs interact in shared cache. 收起
