Report a correction
Much higher clock speed 2.9 GHz vs 1.3 GHz Around 2.2x higher clock speed
Much more l2 cache 2 MB vs 0.5 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Much better overclocked clock speed (Air) 3.64 GHz vs 1.3 GHz More than 2.8x better overclocked clock speed (Air)
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Much better overclocked clock speed (Water) 4 GHz vs 1.3 GHz More than 3x better overclocked clock speed (Water)
More cores 2 vs 1 Twice as many cores; run more applications at once
Better PassMark score 1,690 vs 271 Around 6.2x better PassMark score
