Reasons to consider the
Intel Core i3 2100

Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.1 GHz vs 1.8 GHz More than 70% higher clock speed
Much better geekbench 2 (32-bit) score 4,738 vs 1,427 More than 3.2x better geekbench 2 (32-bit) score
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Significantly more l3 cache per core 1.5 MB/core vs 0.5 MB/core 3x more l3 cache per core
