Essentially a 92 percent AFUE furnace far more efficiently converts the energy input (gas, oil, etc.) into heat. For example, gas is measured in BTUs so a 92 percent AFUE converts 92 of 100 BTUs into heat. An 80 percent furnace converts 80 out of every 100.

This is rather simplified, but should demonstrate that there is a significant difference in efficiency between an 92 AFUE and 80 AFUE furnace in terms of energy and money savings. By the way, a 95 percent AFUE may qualify for state and federal tax rebates.

A 92% furnace is a condensing furnace, which means that the furnace produces condensate which must be drained away. Also, the flue requirements and intake air requirements are going to be different than an 84% efficient furnace. It probably has an ECM (electrically computating motor) for the blower motor, too.
