[ GLOSSARY DEFINITION ] Performance

Power Efficiency

How much performance a chip delivers per watt of power; high efficiency means longer battery and cooler operation.

Also known as: Performance per Watt PPW Efficiency

Full Definition & Technical Explanation

Power efficiency measures performance per watt (e.g., Geekbench 6 Multi / Watt: 236.4 PPW). Smaller nodes and efficiency cores improve it.

CompareTech shows an Efficiency score. Efficient chips let thin devices run cool and extend battery life.
