Reasons to consider the
Intel Pentium E5200

Report a correction
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
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
Significantly better overclocked clock speed (Air) 3.78 GHz vs 2.73 GHz Around 40% better overclocked clock speed (Air)
Newer Jul, 2008 vs Feb, 2005 Release date over 3 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
Higher Maximum operating temperature 74.1 °C vs 67 °C More than 10% higher Maximum operating temperature
Better performance per watt 1.6 pt/W vs 0.46 pt/W More than 3.5x better performance per watt
Significantly better overclocked clock speed (Water) 3.9 GHz vs 2.6 GHz More than 50% better overclocked clock speed (Water)
