Report a correction
Newer manufacturing process 22 nms vs 250 nms A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.5 GHz vs 0.27 GHz Around 13x higher clock speed
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
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
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Slightly newer Jun, 2013 vs Apr, 1999 Release date over 14 years later
More cores 4 vs 1 3 more cores; run more applications at once
More threads 8 vs 1 7 more threads
