Reasons to consider the
Intel Core2 Quad Q8200

Report a correction
Much more l2 cache 4 MB vs 1 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 2.33 GHz vs 1.06 GHz Around 2.2x higher clock speed
Much better overclocked clock speed (Air) 3.07 GHz vs 1.07 GHz More than 2.8x better overclocked clock speed (Air)
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
More cores 4 vs 2 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 3.5 GHz vs 1.07 GHz More than 3.2x better overclocked clock speed (Water)
