The Garmin GTN-750 is more than a "super-sized" GTN-650, although that is the most obvious difference.
This larger size not only allows the GTN-750 to show more information, it allows that information to be more usable and digestible.

GTN-650: The GTN-650 is 2.65" tall, and the display measures 4.9" diagonally. The display shows 600 x 266 pixels.
GTN-750: The GTN-750 is significantly taller, at 6". This accommodates a display which measures 6.9" diagonally. The display shows 600 x 708 pixels.

The GTN-750 display measures "only" 41% larger in corner-to-corner size.
However, the true measurement is the information it conveys to the pilot.
The GTN-750 shows 166% more information, more than twice as much as the GTN-650.
In fact, the GTN-750 is closer to triple the GTN-650's content than double.

This larger display size allowed Garmin to format the GTN-750's display for greater effectiveness.
For example, the GTN-750 feature include:

The COMM and NAV frequencies are at the top of the display (rather than the side),
which opens up a dramatically wider and more informative Moving Map / MFD.
The larger touchscreen display allows direct data entry, rather than scrolling on the GTN-650.
The display can show FliteCharts, which are reproduced AeroNav Services terminal procedures charts. (Please note that the aircraft position is not shown.)
The display can also show Garmin ChartView, which are reproduced Jeppesen terminal procedures charts.
The aircraft position is shown with ChartView for better awareness.
The GTN-750 is capable of acting as a Weather Radar Indicator for the Garmin GWX-68 / GWX-70 / GWX-75 Transmitter / Receiver.
