Why has the shared cache size of the Intel® Core™ i7 processor and Intel® Core™ i5 processor been reduced when compared to the Intel® Core™2 Quad processor?
Although the total amount of shared cache has been reduced for the Intel® Core™ i7 and Intel® Core™ i5 processor families, it now has one shared L3 cache instead of 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 these processors, further improving overall cache performance.
