Report a correction
Much lower typical power consumption 32.5W vs 135.63W 4.2x lower typical power consumption
Much newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More l3 cache 12 MB vs 8 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Significantly more l3 cache per core 3 MB/core vs 2 MB/core 50% more l3 cache per core
Much lower annual home energy cost 9.64 $/year vs 48.38 $/year 5x lower annual home energy cost
Much lower annual commercial energy cost 35.04 $/year vs 134.55 $/year 3.8x lower annual commercial energy cost
Newer Mar, 2010 vs Oct, 2008 Release date over 1 years later
Better performance per watt 1.92 pt/W vs 1.21 pt/W Around 60% better performance per watt
