Report a correction
Much better geekbench 3 AES single core score 79,500 MB/s vs 50,100 MB/s Around 60% better geekbench 3 AES single core score
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher clock speed 1.86 GHz vs 1.2 GHz More than 55% higher clock speed
Much better overclocked clock speed (Air) 3.19 GHz vs 1.27 GHz More than 2.5x 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) 3.45 GHz vs 1.2 GHz Around 3x better overclocked clock speed (Water)
