Reasons to consider the
Intel Pentium 4 670

Report a correction
Much higher clock speed 3.8 GHz vs 1 GHz More than 3.8x higher clock speed
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
Much newer manufacturing process 90 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
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
