Differences What are the advantages of each

Front view of Intel Pentium D 820

Reasons to consider the
Intel Pentium D 820

Report a correction
Much newer manufacturing process 90 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 2.8 GHz vs 0.85 GHz More than 3.2x higher clock speed
Much more l2 cache 2 MB vs 0.06 MB More than 33.2x more l2 cache; more data can be stored in the l2 cache for quick access later
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 0.06 MB/core Around 16.8x more l2 cache per core
Much better overclocked clock speed (Air) 3.52 GHz vs 1.26 GHz More than 2.8x better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 4.25 GHz vs 0.85 GHz More than 5x better overclocked clock speed (Water)
More cores 2 vs 1 Twice as many cores; run more applications at once
