With this survey, its 31st since 1993, the Top500 began measuring computer efficiency as well. The Top500 most energy efficient supercomputers are:
- IBM QS22 Cell processor blades (up to 488 Mflop/s/Watt)
- IBM BlueGene/P systems (up to 376 Mflop/s/Watt)
- Intel Harpertown quad-core blades are catching up fast
- IBM BladeCenter HS21with low-power processors (up to 265 Mflop/s/Watt)
- SGI Altix ICE 8200EX Xeon quad-core nodes, (up to 240 Mflop/s/Watt)
- Hewlett-Packard Cluster Platform 3000 BL2x220 with double density blades (up to 227 Mflop/s/Watt)
- These systems are already ahead of BlueGene/L (up to 210 Mflop/s/Watt).
- The average power consumption of a Top10 system is 1.32 Mwatt and average power efficiency is 248 Mflop/s/Watt.
- The average power consumption of a Top50 system is 908 Kwatt and average power efficiency is 193 Mflop/s/Watt.
- The average Power consumption of a Top500 system is 257 Mwatt and average power efficiency is 122 Mflop/s/Watt.
