Report a correction
Much newer manufacturing process 32 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 4 MB vs 0.25 MB 16x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Higher clock speed 1.9 GHz vs 1.6 GHz Around 20% higher clock speed
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
More cores 4 vs 1 3 more cores; run more applications at once
Better PassMark (Single core) score 848 vs 467 More than 80% better PassMark (Single core) score
Better PassMark score 2,657 vs 305 Around 8.8x better PassMark score
More threads 4 vs 1 3 more threads
Better overclocked clock speed (Air) 2.34 GHz vs 1.81 GHz Around 30% better overclocked clock speed (Air)
Better overclocked clock speed (Water) 1.9 GHz vs 1.6 GHz Around 20% better overclocked clock speed (Water)
