More l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Significantly better overclocked clock speed (Air) 3.2 GHz vs 1.9 GHz Around 70% better overclocked clock speed (Air)
Better PassMark (Single core) score 820 vs 242 Around 3.5x better PassMark (Single core) score
Better PassMark score 1,901 vs 297 Around 6.5x better PassMark score
Much better overclocked clock speed (Water) 3.2 GHz vs 1.67 GHz More than 90% better overclocked clock speed (Water)

Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Higher clock speed 1.66 GHz vs 1.3 GHz Around 30% higher clock speed
Lower typical power consumption 4.47W vs 17.06W 3.8x lower typical power consumption
Newer Jan, 2010 vs Jun, 2005 Release date over 4 years later
Lower annual home energy cost 1.32 $/year vs 5.06 $/year 3.8x lower annual home energy cost
Lower annual commercial energy cost 4.82 $/year vs 18.4 $/year 3.8x lower annual commercial energy cost
