AMD Phenom II X4 965

Report a correction
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 45 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.4 GHz vs 1.4 GHz Around 2.5x higher clock speed
More cores 4 vs 1 3 more cores; run more applications at once
More threads 4 vs 1 3 more threads
Much better overclocked clock speed (Air) 4.05 GHz vs 2.05 GHz More than 95% better overclocked clock speed (Air)
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much more l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Much better overclocked clock speed (Water) 4.22 GHz vs 1.4 GHz More than 3x better overclocked clock speed (Water)
