Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Higher clock speed 3.3 GHz vs 3 GHz Around 10% higher clock speed
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
More threads 4 vs 2 Twice as many threads
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
Newer Jan, 2011 vs Oct, 2004 Release date over 6 years later
Higher Maximum operating temperature 69.1 °C vs 67.7 °C Almost the same
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
