Much more l2 cache 12 MB vs 0.25 MB 48x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 90 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache per core 6 MB/core vs 0.25 MB/core 24x more l2 cache per core
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
Supports more CPUs in SMP configuration 4 vs 2 Twice as many CPUs in SMP configuration
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Newer Jul, 2006 vs Oct, 1999 Release date over 6 years later
More threads 4 vs 1 3 more threads
More cores 2 vs 1 Twice as many cores; run more applications at once
