Također CPU uvijek koristi sav svoj L2 cache

To baš nije istina. Q6600, o kojem je bilo govora ne može iskoristiti u igrama 8MB cachea. Bila je jedna lijepa rasprava davno, dok je još Drago bio na forumu. Neda mi se sada tražiti
, ali zaključak je bio da zbog spajanja dva E6600 procesora, nije moguće koristiti u single aplikaciji sav cache. U tom threadu je bilo sve lijepo objašnjeno...al ga ne mogu naći preko tražilice.
Super pi je odličan pokazatelj da Q6600 koristi 4MB cache, tj rez uz istu frekvu i istom kompu će biti isti kao i s E6600.
Evo nešto kaj sam na brzinu našao:

Although the Kentsfield does include two 4MB Core 2 processors, it also means that many Core 2 features are not fully realized. Core 2 processors feature either 2MB or 4MB of Advanced Smart Cache, which is shared between the two cores. This allows the Core 2 processor a great deal of flexibility, and it could allocate all 4MB of L2 cache to a single core in gaming scenarios, while dynamically shifting the L2 cache between cores in a multi-threading environment. This type of flexibility is not present in the Kentsfield core, there is no facility for sharing of the 8MB of total L2 cache, and instead it acts like dual Core 2 processors, each sharing 4MB of L2 cache. This also affects the entire processor, with absolutely no shared resources between the dual processor dies, resulting in duplication between the two distinct processors.
There are still some advantages to the architecture. The entire L2 cache is not shared, but there is still a total of 8MB, with each Core 2 unit able to dynamically allocate its own 4MB share.
