Roadrunner is also one of the most energy efficient systems on the Top500

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

  • 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.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
