Reasons to consider the
Intel Pentium G2020

Report a correction
Much newer manufacturing process 22 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much lower typical power consumption 44.69W vs 77.19W More than 40% lower typical power consumption
Significantly more l3 cache per core 1.5 MB/core vs 0.5 MB/core 3x more l3 cache per core
Significantly better PassMark (Single core) score 1,560 vs 951 Around 65% better PassMark (Single core) score
Slightly more l3 cache 3 MB vs 1 MB 3x more l3 cache; more data can be stored in the l3 cache for quick access later
Newer Jan, 2013 vs Aug, 2007 Release date over 5 years later
Much lower annual home energy cost 13.25 $/year vs 22.89 $/year More than 40% lower annual home energy cost
Much lower annual commercial energy cost 48.18 $/year vs 83.22 $/year More than 40% lower annual commercial energy cost
Better performance per watt 2.11 pt/W vs 1.3 pt/W More than 60% better performance per watt
Better overclocked clock speed (Water) 3.1 GHz vs 2.8 GHz More than 10% better overclocked clock speed (Water)
