Report a correction
Much more l3 cache 6 MB vs 1 MB 6x more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much lower typical power consumption 60.94W vs 96.69W More than 35% lower typical power consumption
Much more l3 cache per core 1.5 MB/core vs 0.5 MB/core 3x more l3 cache per core
More threads 4 vs 2 Twice as many threads
Much lower annual commercial energy cost 65.7 $/year vs 104.24 $/year More than 35% lower annual commercial energy cost
Much lower annual home energy cost 18.07 $/year vs 28.67 $/year More than 35% lower annual home energy cost
Newer Feb, 2009 vs Aug, 2007 Release date over 1 years later
