Report a correction
Much more l2 cache 6 MB vs 2 MB 3x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3 GHz vs 1.6 GHz More than 85% higher clock speed
Much more l2 cache per core 3 MB/core vs 1 MB/core 3x more l2 cache per core
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much lower typical power consumption 52.81W vs 84.5W Around 40% lower typical power consumption
Much lower annual home energy cost 15.66 $/year vs 25.05 $/year Around 40% lower annual home energy cost
Much lower annual commercial energy cost 56.94 $/year vs 91.1 $/year Around 40% lower annual commercial energy cost
