Reasons to consider the
Intel Core2 Duo E8400

Report a correction
Much more l2 cache 6 MB vs 0.5 MB 12x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 3 GHz vs 1.6 GHz More than 85% higher clock speed
Much better geekbench 2 (32-bit) score 2,826 vs 586 More than 4.8x better geekbench 2 (32-bit) score
Much newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache per core 3 MB/core vs 0.5 MB/core 6x more l2 cache per core
Much better overclocked clock speed (Air) 4.22 GHz vs 1.79 GHz More than 2.2x better overclocked clock speed (Air)
Significantly better PassMark (Single core) score 1,251 vs 433 Around 3x better PassMark (Single core) score
Much better overclocked clock speed (Water) 4.23 GHz vs 1.6 GHz Around 2.8x better overclocked clock speed (Water)
Better PassMark score 2,160 vs 407 More than 5.2x better PassMark score
More cores 2 vs 1 Twice as many cores; run more applications at once
