The shared number
Both list 70 pints per day at the same warm rating point. Cooler-condition figures use different temperatures, so they are shown separately rather than turned into a score.
The space you actually need
Compact70 is listed at 21 inches deep. Ultra70 is 28 inches with duct collars and 22 inches without them. Both list 12-inch cabinet height and width. Add airflow, service and drain space from the exact manual; the cabinet dimensions alone do not decide the installed footprint.
