2 unrelated signals and a clock. Real signal takes some time to settle down at the correct output while the ideal signal always does so instantly.

An ideal logic gate is a logic gate performing operations on boolean values in an abstraction - dissipating no power and changing states instantaneously, similar to a step function. Such gates operate on discrete logic inputs and ignore most physical characteristics such as propegation delay, maximum fan-out, and various other electrical characteristics.

Usage

Ideal logic gates are used in a wide variety of settings since it allows a person to make key observations about a particular circuit without diving into the full specifications.
