Front view of Intel Pentium 4 631

Reasons to consider the
Intel Pentium 4 631

Report a correction
Much higher clock speed 3 GHz vs 1.8 GHz More than 65% higher clock speed
Much more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 65 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 4.36 GHz vs 2.25 GHz Around 95% better overclocked clock speed (Air)
Much more l2 cache per core 2 MB/core vs 0.5 MB/core 4x more l2 cache per core
Much better overclocked clock speed (Water) 4.64 GHz vs 1.8 GHz More than 2.5x better overclocked clock speed (Water)
