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