Much better performance per dollar 7.87 pt/$ vs 0.53 pt/$ Around 14.8x better performance per dollar
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
Much better performance per watt 60.81 pt/W vs 14.35 pt/W Around 4.2x better performance per watt
More cores 4 vs 2 Twice as many cores; run more applications at once
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Better overclocked clock speed (Water) 1.83 GHz vs 1.5 GHz More than 20% better overclocked clock speed (Water)
