Much more l2 cache 8 MB vs 2 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 2.33 GHz vs 2 GHz More than 15% higher clock speed
More cores 4 vs 2 Twice as many cores; run more applications at once
Much more l2 cache per core 2 MB/core vs 1 MB/core 2x more l2 cache per core
Newer manufacturing process 65 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More threads 4 vs 2 Twice as many threads
Lower typical power consumption 65W vs 77.19W More than 15% lower typical power consumption
Lower annual commercial energy cost 70.08 $/year vs 83.22 $/year More than 15% lower annual commercial energy cost
Lower annual home energy cost 19.27 $/year vs 22.89 $/year More than 15% lower annual home energy cost
