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 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better geekbench 2 (32-bit) score 2,826 vs 838 More than 3.2x 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
More threads 2 vs 1 Twice as many threads
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
Higher clock speed 3 GHz vs 2.8 GHz More than 5% higher clock speed
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 higher Maximum operating temperature 72.4 °C vs 67.7 °C More than 5% higher Maximum operating temperature
Newer Jan, 2008 vs Nov, 2000 Release date over 7 years later
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
