computing power
The ability of a computer or processor to carry out a certain amount of calculations or process data in a given time. It is a measure of a system's performance.
Für moderne Videospiele benötigt man einen Computer mit hoher Rechenleistung.
For modern video games, you need a computer with high computing power.
'Rechenleistung' (computing power) is made up of the verb 'rechnen' (to calculate) and the noun 'Leistung' (performance/power), connected by an '-s-'. So it literally means 'performance in calculating'.
Die Rechenleistung des neuen Chips ist beeindruckend.
The computing power of the new chip is impressive.
This noun is very often combined with adjectives that describe its strength. Typical examples are 'hohe' (high), 'enorme' (enormous), 'geringe' (low), or 'ausreichende' (sufficient) Rechenleistung (computing power).
Für künstliche Intelligenz braucht man eine enorme Rechenleistung.
For artificial intelligence, you need enormous computing power.
'Rechenleistung' (computing power) is a technical term from computer science and technology. It is used mainly when talking about the speed and capacity of computers, processors, or graphics cards.
Die Grafikkarte bestimmt maßgeblich die Rechenleistung für Spiele.
The graphics card largely determines the computing power for games.
performance
'die Performance' and 'die Rechenleistung' can both describe how well a computer or technical system works. 'Performance' is broader and often refers to overall speed and usability, for example how quickly a program starts or a website loads. 'Rechenleistung' is more precise and means the ability to handle calculations and data processing. Learners may confuse the words because both have to do with technology and speed. If it is about the general impression when using something, 'Performance' fits. If it is about the power of the processor or many calculations, 'Rechenleistung' is more precise.
