GBW (Gain-Bandwidth Product)
For a single-pole amplifier, the constant product of closed-loop gain and the resulting bandwidth, equal to the unity-gain frequency. It tells you immediately how much bandwidth remains once a given gain is demanded.

Notes
A large-signal step is limited by slew rate instead, so GBW alone never predicts settling time.
