Reasons to consider the
Intel Pentium 4 672

Report a correction
Much higher clock speed 3.8 GHz vs 1.1 GHz Around 3.5x 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) 3.8 GHz vs 1.1 GHz Around 3.5x better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 5.74 GHz vs 1.1 GHz Around 5.2x better overclocked clock speed (Water)

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 lower typical power consumption 13.81W vs 93.44W 6.8x lower typical power consumption
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much higher Maximum operating temperature 100 °C vs 70.8 °C More than 40% higher Maximum operating temperature
Newer Jun, 2011 vs Nov, 2005 Release date over 5 years later
Much lower annual home energy cost 4.1 $/year vs 27.7 $/year 6.8x lower annual home energy cost
Much lower annual commercial energy cost 14.89 $/year vs 100.74 $/year 6.8x lower annual commercial energy cost
More cores 2 vs 1 Twice as many cores; run more applications at once
