Intel Core2 Duo P9500

Report a correction
Much more l2 cache 6 MB vs 1 MB 6x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 45 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly higher clock speed 2.53 GHz vs 1.4 GHz More than 80% higher clock speed
Much more l2 cache per core 3 MB/core vs 1 MB/core 3x more l2 cache per core
Much better overclocked clock speed (Air) 2.9 GHz vs 1.4 GHz More than 2x better overclocked clock speed (Air)
Newer Jul, 2008 vs Feb, 2004 Release date over 4 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
Slightly lower typical power consumption 20.31W vs 24.38W More than 15% lower typical power consumption
Significantly better overclocked clock speed (Water) 2.53 GHz vs 1.4 GHz More than 80% better overclocked clock speed (Water)
Slightly lower annual commercial energy cost 21.9 $/year vs 26.28 $/year More than 15% lower annual commercial energy cost
Slightly lower annual home energy cost 6.02 $/year vs 7.23 $/year More than 15% lower annual home energy cost
