"Each core on 32 +32 KB L1 and 256kB L2 cache access, with the size of the L2 cache, inclusive (i.e. the L1 cache is mirrored in L2 cache) compared to the Core 2 processors with 2-6MB relatively low impact. This is a 8MB large L3 cache will be compensated on the all four cores together and can access the full processor clock is running.

Returned by the famous Pentium 4 Hyper-Threading, which for better utilization of the processing units to be sure. For four real cores thus obtained four additional logical cores in the optimal case for an additional rate increases can boost it."
