Much better geekbench 3 AES single core score 307,700 MB/s vs 24,300 MB/s Around 12.8x better geekbench 3 AES single core score
Much better performance per watt 73.77 pt/W vs 6.04 pt/W Around 12.2x better performance per watt
Much higher turbo clock speed 1.86 GHz vs None Compared to all cpus, 1.86 GHz turbo clock speed is just OK
Much better geekbench 2 (32-bit) score 2,448 vs 1,048 More than 2.2x better geekbench 2 (32-bit) 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
Much newer manufacturing process 22 nm vs 40 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 1.33 GHz vs 1 GHz Around 35% higher clock speed
Better geekbench 3 Multi-Core score 2,572 vs 708 Around 3.8x better geekbench 3 Multi-Core score
More cores 4 vs 2 Twice as many cores; run more applications at once
Better overclocked clock speed (Air) 1.55 GHz vs 1 GHz More than 55% better overclocked clock speed (Air)
Newer Oct, 2013 vs Jun, 2011 Release date over 2 years later
More threads 4 vs 2 Twice as many threads
Slightly higher GPU clock speed 311 MHz vs 276 MHz Around 15% higher GPU clock speed
Better overclocked clock speed (Water) 1.33 GHz vs 1 GHz Around 35% better overclocked clock speed (Water)
