Report a correction
Much more l2 cache 4 MB vs 1 MB 4x 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 better geekbench 2 (32-bit) score 2,396 vs 961 Around 2.5x better geekbench 2 (32-bit) score
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
More cores 2 vs 1 Twice as many cores; run more applications at once
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Much better performance per watt 1.69 pt/W vs 1.1 pt/W Around 55% better performance per watt
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Significantly lower typical power consumption 52.81W vs 68.25W Around 25% lower typical power consumption
Significantly better overclocked clock speed (Water) 3.6 GHz vs 3.2 GHz More than 10% better overclocked clock speed (Water)
Significantly lower annual home energy cost 15.66 $/year vs 20.24 $/year Around 25% lower annual home energy cost
Significantly lower annual commercial energy cost 56.94 $/year vs 73.58 $/year Around 25% lower annual commercial energy cost
Newer Jul, 2006 vs Feb, 2004 Release date over 2 years later
