Rilasciata una nuova versione dell'utility Intel SpeedStep in grado di ottimizzare il risparmio energetico sui NoteBook equipaggiati con CPU Intel della serie Mobile. Questa versione sembrerebbe ottimizzata per i NoteBook IBM ThinkPad R31, cosė come appare dalla news pubblicata da <a href="http://www.3ditalia.com/"></a>.<br><br>La tecnologia Intel SpeedStep consente di ottimizzare il consumo energetico su un NoteBook quanto questo non viene alimentato da rete elettrica, riducendo la frequenza di clock e la tensione di alimentazione della CPU; in tal modo si garantisce una maggiore autonomia di funzionamento del nostro PC.<br><br>Per meglio chiarire il concetto allego una tabella prelevata direttamene dal sito di <a href="http://www.intel.it">Intel</a>:<br><br>
