Reasons to consider the
Intel Pentium D 945

Report a correction
Much more l2 cache 4 MB vs 1 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 3.4 GHz vs 1.2 GHz More than 2.8x 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
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Much better overclocked clock speed (Air) 4.22 GHz vs 1.33 GHz Around 3.2x better overclocked clock speed (Air)
Much more l2 cache per core 2 MB/core vs 1 MB/core 2x more l2 cache per core
Much better overclocked clock speed (Water) 4.59 GHz vs 1.2 GHz More than 3.8x better overclocked clock speed (Water)
More cores 2 vs 1 Twice as many cores; run more applications at once
