leistungsfähiger

Leistungsfähiger is the comparative form of the German adjective leistungsfähig, meaning capable of delivering high performance or output. The term combines Leistung (performance, output) and fähig (able, capable). It is used to compare two entities in terms of their ability to perform, produce results, or operate effectively.

The word is commonly applied to machines, devices, software, and systems where capacity, efficiency, speed, or reliability matter. For example: "Dieses System ist leistungsfähiger als jenes System." or "Ein leistungsfähigerer Motor bietet mehr Leistung und Effizienz." The nuance of leistungsfähig emphasizes overall capability rather than raw power alone; a leistungsfähiger system may be faster, more efficient, or more robust.

In practice, leistungsfähiger is often contrasted with related terms such as leistungsstark, which tends to highlight current high performance or power, rather than broader capability. The term appears in technical writing, engineering documentation, and marketing materials where improvements in capability are described. Grammatically, leistungsfähiger is the comparative form, with am leistungsfähigsten as the superlative. It can be used attributively, as in "ein leistungsfähiger Motor," or predicatively, as in "Der Motor ist leistungsfähiger als der andere." Overall, leistungsfähiger signals a higher level of functional capability relative to another item.
