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
Much better geekbench 2 (32-bit) score 2,197 vs 838 More than 2.5x better geekbench 2 (32-bit) score
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
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
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 lower typical power consumption 28.44W vs 68.25W 2.4x lower typical power consumption
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Newer Oct, 2010 vs Nov, 2000 Release date over 10 years later
Much higher Maximum operating temperature 100 °C vs 67.7 °C Around 50% higher Maximum operating temperature
More cores 2 vs 1 Twice as many cores; run more applications at once
Much lower annual home energy cost 8.43 $/year vs 20.24 $/year 2.4x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 73.58 $/year 2.4x lower annual commercial energy cost
