Electronic chartplotters are by nature [[Central Processing Unit|CPU]] (and [[General-purpose computing on graphics processing units|GPU]]) intensive applications. Chartplotters need to retrieve the Navigation Signal ([[Galileo (satellite navigation)|Galileo]], GPS, [[GLONASS]], [[Wide Area Augmentation System|WAAS]] etc.) signal and overlay that on a map. Map updates on dedicated hardware typically have screen refresh rates from 5 Hz to 30 Hz.

Some navigation software can run on standard computers (and mobile phones, etc.) but most higher end systems are dedicated hardware. Especially when the chartplotter generates three-dimensional displays, as used for fishing, considerable processing power and video memory may be required.
