Reasons to consider the
Intel Pentium D 820

Report a correction
Much newer manufacturing process 90 nm vs 250 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 2 MB vs 0.5 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 2.8 GHz vs 0.6 GHz Around 4.8x 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
More cores 2 vs 1 Twice as many cores; run more applications at once
More threads 2 vs 1 Twice as many threads
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Newer Apr, 2005 vs Sep, 1999 Release date over 5 years later
