Much newer manufacturing process 45 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 3 MB vs 0.25 MB 12x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 2.4 GHz vs 0.6 GHz 4x 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
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 more l2 cache per core 1.5 MB/core vs 0.25 MB/core 6x more l2 cache per core
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 Jul, 2008 vs Oct, 1999 Release date over 8 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
