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
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 27.63W vs 68.25W 2.5x lower typical power consumption
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much more l2 cache per core 2 MB/core vs 1 MB/core 2x more l2 cache per core
More cores 2 vs 1 Twice as many cores; run more applications at once
Much lower annual home energy cost 8.19 $/year vs 20.24 $/year 2.5x lower annual home energy cost
Much lower annual commercial energy cost 29.78 $/year vs 73.58 $/year 2.5x lower annual commercial energy cost
