Front view of Intel Pentium 1403

Reasons to consider the
Intel Pentium 1403

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
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
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Newer May, 2012 vs Oct, 2004 Release date over 7 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
