Reasons to consider the
Intel Core2 Duo SU9300

Report a correction
Much better 3DMark06 CPU score 1,028 vs 23.1 More than 44.5x better 3DMark06 CPU score
Significantly more l2 cache 3 MB vs 2 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Much more l2 cache per core 1.5 MB/core vs 0.5 MB/core 3x more l2 cache per core
