Intel Xeon E3-1220 v2

Report a correction
Much better performance per dollar 4.66 pt/$ vs 1.14 pt/$ More than 4x better performance per dollar
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
Significantly newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much lower typical power consumption 56.06W vs 98.28W Around 45% lower typical power consumption
Much better performance per watt 13.51 pt/W vs 1.41 pt/W More than 9.5x better performance per watt
More l3 cache 8 MB vs 3 MB Around 2.8x more l3 cache; more data can be stored in the l3 cache for quick access later
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
More cores 4 vs 2 Twice as many cores; run more applications at once
Better PassMark score 6,602 vs 3,664 More than 80% better PassMark score
More l3 cache per core 2 MB/core vs 1.5 MB/core Around 35% more l3 cache per core
Much lower annual home energy cost 16.62 $/year vs 37.88 $/year 2.3x lower annual home energy cost
Better PassMark (Single core) score 1,806 vs 1,583 Around 15% better PassMark (Single core) score
Newer May, 2012 vs Jan, 2011 Release date over 1 years later
Significantly lower annual commercial energy cost 60.44 $/year vs 93.47 $/year More than 35% lower annual commercial energy cost
Better overclocked clock speed (Air) 3.45 GHz vs 3.23 GHz More than 5% better overclocked clock speed (Air)
