Reasons to consider the
Intel Celeron J1900

Report a correction
Much better geekbench 3 AES single core score 56,900 MB/s vs 33.3 MB/s Around 1708.8x 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
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Significantly newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
More cores 4 vs 2 Twice as many cores; run more applications at once
Newer Oct, 2013 vs Sep, 2011 Release date over 2 years later
Higher GPU clock speed 688 MHz vs 640 MHz Around 10% higher GPU clock speed
Better performance per watt 4.31 pt/W vs 2.89 pt/W Around 50% better performance per watt
Slightly better PassMark score 1,863 vs 839 Around 2.2x better PassMark score
Better overclocked clock speed (Air) 2.42 GHz vs 2.13 GHz Around 15% better overclocked clock speed (Air)
Better overclocked clock speed (Water) 2.42 GHz vs 2.13 GHz Around 15% better overclocked clock speed (Water)
