Front view of Intel Pentium D 945

Reasons to consider the
Intel Pentium D 945

Report a correction
Much more l2 cache 4 MB vs 0.13 MB 32x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 3.4 GHz vs 1.8 GHz Around 90% higher clock speed
Much newer manufacturing process 65 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
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 0.13 MB/core 16x more l2 cache per core
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
