leistungsfähige

Leistungsfähig is a German adjective meaning capable of performing at a given level, efficient, or high-performing. The attributive form leistungsfähige is used before feminine singular nouns in the nominative or accusative case and before plural nouns. The base form can also appear after a definite article or in other declension patterns as leistungsfähige, leistungsfähiger, or leistungsfähiges depending on gender, number, and case. The corresponding predicative form is leistungsfähig, as in Der Motor ist leistungsfähig.

Etymology and usage notes: leistungsfähig is formed from Leistung (performance, power) and fähig (able). It is widely used in technical, engineering, and business contexts to describe systems, components, or processes that meet required performance levels. The phrase leistungsfähige Systeme, leistungsfähige Komponenten or leistungsfähige Rechenleistung is common in descriptions of capability and capacity.

Contexts and nuance: The term emphasizes capability rather than an extreme performance level. It is often contrasted with formulations such as hochleistungsfähig (high-performance capable) to stress a particularly high capability, or with leistungsstark to highlight strength of performance. In daily language, it can describe devices, infrastructure, or organizations that can operate effectively under expected conditions.

Examples: leistungsfähige Hardware, eine leistungsfähige Batterie, leistungsfähige Software, leistungsfähige Motoren. In sentence form: Die neue Serverhardware sorgt für leistungsfähige Rechenleistung. Sie benötigen eine leistungsfähige Energieversorgung.
