Reasons to consider the
Intel Pentium 4 662

Report a correction
Significantly higher clock speed 3.6 GHz vs 2.4 GHz More than 50% higher clock speed
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l2 cache per core 2 MB/core vs 0.5 MB/core 4x more l2 cache per core
Much better overclocked clock speed (Air) 4.18 GHz vs 2.68 GHz More than 55% better overclocked clock speed (Air)
Significantly better overclocked clock speed (Water) 3.6 GHz vs 2.4 GHz More than 50% better overclocked clock speed (Water)

Intel Core i5 450M

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
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much lower typical power consumption 28.44W vs 93.44W 3.3x lower typical power consumption
Newer Jun, 2010 vs Nov, 2005 Release date over 4 years later
Much lower annual home energy cost 8.43 $/year vs 27.7 $/year 3.3x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 100.74 $/year 3.3x lower annual commercial energy cost
More cores 2 vs 1 Twice as many cores; run more applications at once
More threads 4 vs 2 Twice as many threads
