Much 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
Much better overclocked clock speed (Air) 3.87 GHz vs 2.8 GHz Around 40% better overclocked clock speed (Air)
Higher clock speed 3 GHz vs 2.8 GHz More than 5% higher clock speed
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Lower typical power consumption 52.81W vs 59.31W More than 10% lower typical power consumption
Much better overclocked clock speed (Water) 4.2 GHz vs 2.8 GHz Around 50% better overclocked clock speed (Water)
Higher Maximum operating temperature 74.1 °C vs 72.6 °C Almost the same
Lower annual commercial energy cost 56.94 $/year vs 63.95 $/year More than 10% lower annual commercial energy cost
Lower annual home energy cost 15.66 $/year vs 17.59 $/year More than 10% lower annual home energy cost
