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 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
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
Much better overclocked clock speed (Air) 4.22 GHz vs 2.48 GHz More than 70% better overclocked clock speed (Air)
Significantly better PassMark (Single core) score 1,251 vs 513 Around 2.5x better PassMark (Single core) score
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Better PassMark score 2,160 vs 951 More than 2.2x better PassMark score
Much better overclocked clock speed (Water) 4.23 GHz vs 2.48 GHz More than 70% better overclocked clock speed (Water)
