Reasons to consider the
Intel Core i3 2375M

Report a correction
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Much newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
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
Higher clock speed 1.5 GHz vs 1.3 GHz More than 15% higher clock speed
Better performance per watt 5.16 pt/W vs 3.07 pt/W Around 70% better performance per watt
Better performance per dollar 0.39 pt/$ vs 0.2 pt/$ More than 90% better performance per dollar
Newer Jan, 2013 vs Sep, 2010 Release date over 2 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
Better PassMark score 1,778 vs 271 More than 6.5x better PassMark score
More threads 4 vs 2 Twice as many threads
Slightly better overclocked clock speed (Air) 1.5 GHz vs 1.3 GHz More than 15% better overclocked clock speed (Air)
Slightly better overclocked clock speed (Water) 1.5 GHz vs 1.3 GHz More than 15% better overclocked clock speed (Water)
