Why has the shared cache size of the Intel Core i7 processor been reduced compared to the Intel Core2 Quad processor?
– Answer: Although the total amount of shared cache has been reduced for the Intel Core i7 processor, it now has one shared L3 cache vs. two separate L2 caches. The new L3 cache is inclusive which improves efficiency by reducing the amount of snoops needed. A 256K L2 data and instruction cache also has been added to each core of the Intel Core i7 processor, further improving overall cache performance.
