Much more l2 cache 3 MB vs 0.5 MB 6x more l2 cache; more data can be stored in the l2 cache for quick access later
More cores 6 vs 2 Three times as many cores; run more applications at once
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
More l3 cache 6 MB vs 3 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Lower typical power consumption 28.44W vs 44.69W More than 35% lower typical power consumption
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
More threads 6 vs 4 2 more threads
Lower annual home energy cost 8.43 $/year vs 13.25 $/year More than 35% lower annual home energy cost
Lower annual commercial energy cost 30.66 $/year vs 48.18 $/year More than 35% lower annual commercial energy cost
