what else do u want.. intel does't want to increase the cache size.. beside that.. bigger cache are slower and more expensive to manufacture

hint...

y do u need 4mb L2 cache.. and not 4MB L1 cache???

think of it as waterfall effect.. L1 overflows to L2 overflows to L3 overflows to RAM overflows to HDD

isn't is always like that??

the fastest memory in CPU is called the register..

small & fast cache is nearer to the core while bigger and slower is further..

with the exception of duron.. its second level is half the size of its L1 cache.. coz its exclusive cache

exclusive cache means content of L1 is not duplicated into L2.. eg

if exclusive = 128KB L1 + 256 KB L2 = 384KB effective cache or in the case of duron, its 128KB L1 + 64KB L2 = 192KB effective cache..

if inclusive = 128KB L1 + 256 KB L2 = 256KB effective cache.. of coz.. whatever reside in L1 will still be accessed quicker.
