Report a correction
Much newer manufacturing process 32 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 4 MB vs 0.25 MB 16x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly higher clock speed 1.4 GHz vs 0.6 GHz More than 2.2x 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
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 Jun, 2011 vs Oct, 1999 Release date over 11 years later
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
More cores 4 vs 1 3 more cores; run more applications at once
Significantly higher Maximum operating temperature 100 °C vs 82 °C More than 20% higher Maximum operating temperature
More threads 4 vs 1 3 more threads
