Reasons to consider the
Intel Pentium D 945

Report a correction
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
Much higher clock speed 3.4 GHz vs 1.67 GHz More than 2x higher clock speed
Much newer manufacturing process 65 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 4.22 GHz vs 2.17 GHz Around 95% better overclocked clock speed (Air)
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 2 MB/core vs 0.25 MB/core 8x 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) 4.59 GHz vs 1.67 GHz More than 2.8x better overclocked clock speed (Water)
Newer Jul, 2006 vs Jul, 2004 Release date over 1 years later
