Intel Core2 Duo L7400

Report a correction
Much more l2 cache 4 MB vs 2 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 65 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 68.25W 4.9x lower typical power consumption
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much lower annual home energy cost 4.1 $/year vs 20.24 $/year 4.9x lower annual home energy cost
Much lower annual commercial energy cost 14.89 $/year vs 73.58 $/year 4.9x lower annual commercial energy cost
More cores 2 vs 1 Twice as many cores; run more applications at once
Newer Jul, 2006 vs Oct, 2005 Release date 9 months later
