Higher clock speed 3.4 GHz vs 3.2 GHz More than 5% higher clock speed
Lower typical power consumption 52.81W vs 59.31W More than 10% lower typical power consumption
Higher Maximum operating temperature 74 °C vs 72.6 °C Almost the same
Better overclocked clock speed (Water) 3.4 GHz vs 3.2 GHz More than 5% better overclocked clock speed (Water)
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
Newer Dec, 2010 vs Apr, 2010 Release date 8 months later
