Report a correction
Much newer manufacturing process 22 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 2 MB vs 0.5 MB 4x 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
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much lower typical power consumption 1.79W vs 66.54W 37.2x lower typical power consumption
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
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
Newer Apr, 2014 vs Apr, 2003 Release date over 11 years later
More cores 4 vs 1 3 more cores; run more applications at once
Significantly higher Maximum operating temperature 90 °C vs 70 °C Around 30% higher Maximum operating temperature
Much lower annual home energy cost 0.53 $/year vs 19.73 $/year 37.2x lower annual home energy cost
Much lower annual commercial energy cost 1.93 $/year vs 71.74 $/year 37.2x lower annual commercial energy cost
More threads 4 vs 2 Twice as many threads
