Reasons to consider the
Intel Core i3 330M

Report a correction
Much newer manufacturing process 32 nm vs 250 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 2.13 GHz vs 0.53 GHz More than 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
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
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 l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
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 Jan, 2010 vs Sep, 1999 Release date over 10 years later
More threads 4 vs 1 3 more threads
More cores 2 vs 1 Twice as many cores; run more applications at once
