Report a correction
Much more l3 cache per core 9 MB/core vs 2 MB/core 4.5x more l3 cache per core
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly more l3 cache 18 MB vs 8 MB 2.2x more l3 cache; more data can be stored in the l3 cache for quick access later
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Higher Maximum operating temperature 76 °C vs 64 °C Around 20% higher Maximum operating temperature

Report a correction
Much newer manufacturing process 14 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 4 GHz vs 1.6 GHz Around 2.5x higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Newer Jul, 2015 vs Oct, 2007 Release date over 7 years later
Lower typical power consumption 73.94W vs 84.5W Around 15% lower typical power consumption
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 8 vs 4 Twice as many threads
Lower annual home energy cost 21.92 $/year vs 25.05 $/year More than 10% lower annual home energy cost
Lower annual commercial energy cost 79.72 $/year vs 91.1 $/year Around 15% lower annual commercial energy cost
