Energy Consumption: Loading the Processor to the Maximum
Things change quite a bit when the processor is loaded to its limit. The single core Sempron 64 processors now take the lead with up to 33 W; the BE processors have more computing power, and with up to 35.8 watts, are more efficient. The energy efficient CPUs’ energy intake goes to between 40.2 and 59.2 Watts, while the Athlon 64 processors hold the record high at 59.5 to 102.4 Watts.
The quad core Phenom models do better than the two core Athlon 64 processors. With programs that benefit from quad core processors, the Phenom is more efficient than the Athlon 64.
