Energy-efficient quad-core Xeon chips from Intel

Intel has recently made the launch of two low-voltage, 45-nanometer server processors that are remarkable energy efficient. Energy-efficient processors are gaining more attention as companies increasingly look to go green in order to save both power and money.

The quad-core Xeon L5400 Series chips run at 50 watts -- or 12.5 watts per core -- but their performance still reaches the 2.5-GHz mark. The new Intel Xeon processors have a 50% larger cache than its previous-generation along with the low-voltage quad-core Xeon processors. These new processors also have 12MB of on-die cache and dedicated 1333-MHz front-side buses.
