Reasons to consider the
Intel Celeron J1800

Report a correction
Significantly higher clock speed 2.41 GHz vs 1.46 GHz More than 65% higher clock speed
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
More l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher GPU clock speed 688 MHz vs 400 MHz More than 70% higher GPU clock speed
Significantly better overclocked clock speed (Air) 2.58 GHz vs 1.47 GHz More than 75% better overclocked clock speed (Air)
Better geekbench 3 Multi-Core score 1,661 vs 627 Around 2.8x better geekbench 3 Multi-Core score
Better PassMark (Single core) score 554 vs 316 More than 75% better PassMark (Single core) score
More cores 2 vs 1 Twice as many cores; run more applications at once
Significantly better overclocked clock speed (Water) 2.58 GHz vs 1.47 GHz More than 75% better overclocked clock speed (Water)
