Reasons to consider the
Intel Pentium D 820

Report a correction
Much more l2 cache 2 MB vs 0.25 MB 8x more l2 cache; more data can be stored in the l2 cache for quick access later
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
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much better overclocked clock speed (Water) 4.25 GHz vs 2.8 GHz More than 50% better overclocked clock speed (Water)
Newer Apr, 2005 vs Jun, 2004 Release date 9 months later
